Ubuntu :: Drive Keeps Failing Out Of Software RAID?
Jan 26, 2010
I have 4 1.5 TB Seagate drives configured in RAID 5 via mdadm on Karmic. It seems that after a while, one drive always drops out of the array. It's a brand new drive, and after a reboot, it will come back in and rebuild just fine, so somehow I doubt the drive is actually failing. Here's a dmesg snip. The mounting that happens at the top is the mounting of the array, and as you can see, after a while, there is some kind of write failure.
[70178.385356] EXT3 FS on md0, internal journal
[70178.385373] EXT3-fs: mounted filesystem with writeback data mode.

How long does hardware Raid card (raid 1, 2 drives)take to mirror a 1 TB drive (500gb used)?Is there a general rule of thumb for this?4 hours? 12 hours? 24 hours?

extract some data off a failing drive the other day. I plugged it in, but got no response in windows or linux (partition is ntfs), but it does appear in the bios and /dev (though the hdd hung most linux liveCDs except rescue remix 9.04). I tried to analyze the drive, and found good smart data, so I figured there were just a few bad blocks in critical places. I ran spinrite against it in level 2 mode. the process crawled (40MB after 2 hours) and it updated the smart data to reflect many many reallocated sectors, putting the drive into a failing state as far as smart is concerned. so, now, in a last ditch effort I am turning to ddrescue to try to get an image of the drive. it's been running about 17 hours now, and has done several complete passes through "Splitting error areas".
here is my current output:
Code:
Disk /dev/sdb: 320.0 GB, 320072933376 bytes
255 heads, 63 sectors/track, 38913 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
[code]....
have I done all I can? can I in good conscious declare this a lost cause? I do have an image from a prior run of ddrescue, with 826 MB of data.
edit: I resumed the task from log, and now it is reporting the err size as 9223 PB. since the drive is a 320GB, I find that a bit odd.

I have 2 500gb drives in my system. One of the drives I use for swap and home is failing, good thing it is under warranty... Bad thing I have to remove the drive from my system.
I have / on the first drive taking it all up. On the drive that needs replaced I have /swap and /home taking up the whole drive.
Is there a way to shrink /dev/sda to put swap and home on that drive and to move it back when new drive arrives? Or would it be simpler to just re-install to one drive?

I have an external HD attached to my desktop and setup as a shared resource. I want to be able to access it from my laptop as well. After much trying and drinking, I ended up with this in fstab:
//crackbox/seagate /seagate -o
then began giving me an error about not recognizing the file system type. I've been reading everything I can find and trying to get it to work, and have come up with very little. My fstab now contains this line instead of the above:

Now, when I reload fstab with "sudo mount -a", I get this output:

I have a 2 Tb drive that Linux is saying is failing, the reason for this is Relocated Secotor Count, should i really worry and why is it happening to such a new drive its only 4 months old I received it on December 30th I woudl think it would not be bad at this point.

my linux server is running with an old IDE hard drive getting these hdparm results:
[code]...
i have a WD Raptor drive i'm going to install and put a fresh install of linux on it. i'm just curious, will using a much faster HD as my main drive increase the speeds of my network transfers from the raid drive? do transfers only go as fast as the system drive?

I made an attempt to backup my system (karmic koala) using this routine. cd / then sudo tar cvpzf backup.tgz --exclude=/proc --exclude=/lost+found --exclude=/backup.tgz --exclude=/mnt --exclude=/sys /
The process of backup went on for a very long time, which is probably normal. On returning to the computer in the morning, it was in suspend mode and would not power on via the usual method,tapping power button. So then I used the reset button, and after booting up a message appears on the top right that reports "Install problem! The configuration defaults for GNOME Power Manager have not been installed correctly. Please contact your computer administrator."
Is there something wrong with the statement that was used for backing up the system? Also when I attempt to login it does not work now either, it eventually returns to the login user selection. So is there a possibility the backup finished and then there may be a chance the system can be restored from the backup file? I have tried booting up with a live cd and could use some advice on how to navigate with terminal to root of the system and see if the backup file exist even, have been unable to get to the root folder(where the backup would be) with the GUI method via live cd.

I seem to have a complex issue on my hands that i can't figure out. first, i wasn't able to get access to my LVM'd hard drives via SSH without half of the content being missing or locked out (read-only or unable to open at all). the problem then went up to being unable to boot up - all i got was a long slew of [100.1234] ata1.00: error messages (they eventually DO stop once they get to around 998.234234 or whatever, and then i can log in and it seems to be "stable").
Part way through this rebooting ordeal i realized / decided to make power-on-self-test stop and wait if it finds errors (via bios) - that showed me that my 750G SATA drive is "bad" and my two (older) 120G & 250G IDE drives are "ok". i then unplugged the SATA drive, rebooted, and didn't see those error messages. however, my LVM was still obviously not coming together (since LVM was made up of the 120G, 250G, and 750G drives)
So, now it seems:
a) I can't boot smoothly with all drives in place
b) I can't do anything with lvm if i remove the 750G sata
c) With all drives hooked up, i can wait 10mins for the errors to go away, but STILL can't do anything with lvm
d) I need to recover the lvm stuff so that i can nicely migrate ALL those files (1.1TB of it) onto a new 1.5TB drive and do away with lvm
This is all running ubuntu 7.10 server edition (32-bit version on a 64-bit computer). i DID post a question on the ubuntu forum as well but so far got no replies at all.
Here's a few pics of the booting process, with one or two "fail" lines showing.

I've got an LG CD/DVD player/writer in my desktop, and it's suddenly stopped working. No error messages at all, but it doesn't acknowledge any discs any more, whether they're CDs or DVDs or CDRWs or anything. How can I diagnose what's wrong? It's only 1.5 years old so I wouldn't expect it to be a hardware problem really, but I can't think of anything else. At first I thought I'd broken something with Squeeze, but I ran a live system from USB stick and it also can't read any discs at all. Also I tried a bootable DVD and couldn't get that to boot either, so I'm pretty confident it's not a software problem. It's always worked fine before and hasn't had any shocks or moves or anything (that I know of). The green light flashes when I close the drawer, just flashes a few times and then stops. There's nothing in /var/log/messages. Are there any tricks to figure out what might be wrong or is it looking like I need to buy a replacement drive?

An external 3½" HDD seems to be in danger of failing” it's making ticking sounds when idle. I've acquired a replacement drive, and want to know the best strategy to get the data off of the dubious drive with the best chance of saving as much as possible. There are some directories that are more important than others. However, I'm guessing that picking and choosing directories is going to reduce my chances of saving the whole thing. I would also have to mount it, dump a file listing, and then unmount it in order to be able to effectively prioritize directories. Adding in the fact that it's time-consuming to do this, I'm leaning away from this approach.
I've considered just using dd, but I'm not sure how it would handle read errors or other problems that might prevent only certain parts of the data from being rescued, or which could be overcome with some retries, but not so many that they endanger other parts of the drive from being saved. I guess ideally it would do a single pass to get as much as possible and then go back to retry anything that was missed due to errors.
Is it possible that copying more slowly — e.g. pausing every x MB/GB — would be better than just running the operation full tilt, for example to avoid any overheating issues? For the "where is your backup" crowd: this actually is my backup drive, but it also contains some non-critical and bulky stuff, like music, that aren't backups, i.e. aren't backed up. The drive has not exhibited any clear signs of failure other than this somewhat ominous sound. I did have to fsck a few errors recently — orphaned inodes, incorrect free blocks/inodes counts, inode bitmap differences, zero dtime on deleted inodes; about 20 errors in all.The filesystem of the partition is ext3.

In my laptop I have a 200GB hard drive that is starting to make clicking and grinding noises and won't boot about every third try.
Code:

/dev/sdb is a usb flash drive that has pmagic (not sure of the version, but it's 2.6.32.9-pmagic kernel, so I think it's the latest version). I'm posting from pmagic right now because I don't want the failing disk to get any worse until I get this sorted. I also know there is a post here called something like 'learning the dd command' or 'mastering the dd command' or something to that effect, but I can't find it for the life of me (I have it bookmarked on the failing drive, of course). If someone could point me to that post,

Using F12 with a LVM Volume, Single disk with OS on and boot partition. The OS HDD is getting i/o errors, but will still boot to the login screen. I've removed the HDD and connected it to a Fedora Live OS on my laptop, connected the HDD and it registers as :
[root@localhost]# fdisk -l /dev/sdd
Disk /dev/sdd: 250.1 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x000e0069

Partition 1 does not end on cylinder boundary.
/dev/sdd2 26 30401 243991201 8e Linux LVM
And it tried to mount /dev/sdd2 to view and see if I can recover some files.
[root@localhost]# mount /dev/sdd2 /mnt -t ext4[root@localhost james]# mount /dev/sdd2 /mnt -t ext4
mount: wrong fs type, bad option, bad superblock on /dev/sdd2,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
Any way to mount the partition to allow me to try and get some data back, or if trying to do a full backup of the drive you can get it to ignore i/o errors.

I have a 3 weeks old PC which I've just finished getting set up with Ubuntu 11.04 and W7 in a Virtual Box. Now the drive has started making rumbling noises and doesn't always boot.The engineer from Dell is coming tomorrow to replace the drive, but what can I do about transferring the whole old drive to the new one in full working order, quickly?
I've been using rsync to keep backups of my home folder, so I've got the data side covered. But I don't really want to spend the next couple of weeks re-installing all the software, printers etc all over again. So is there a quick, easy way of replicating the old drive with partitions, VB, etc (I'm not that good at using the terminal) ?

I have an external drive that has been formatted as NTFS and I need to recover the files. For the most part, on windows, I can read the drive however When I'm copying, it interrupts with an I/O failure. Is there a way to copy the files from Linux and have it continue even if it has an error?

I'm using xubuntu on a box that has 2 drives. One is quite small mounted as / and the other larger drive is mounted as /home Both drives are IDE The /home drive has had some failure in the past & occasionally creates errors. Is there any way of identify which sectors are bad (or good) and isolating them to try & get some more use out of the drive?
It won't be used for storing valuable data.It is an old box for visitors to use. But it would be handy to use it to store some large read-only audio files. I've installed smartctl & could post output from there if you think it is useful. I can't work out how to interpret the information.

i have a Sandisk 5gig USB key that had mint 9 live on it that i was hoping to get an old brotasaurus (Dell Latitude D510) up and running again with. apparently Mint is too pretty for the beast and so I tried to get mint Fluxbox to install on to the key, then i tried Fedora, and finaly i tried DSL. Unetbootin seems to have stoped making the key bootable as three of my laps seem unable to read it.
[Update] so i tried dd'ing the iso to the usb following the instructions on the suse site
# umount /dev/sdb1
# dd if=/home/Derf/Downloads/dsl-4.4.10.iso of=/dev/sdb1 bs=4M;sync
and it is still failing to create a bootable usb. says

I have an hp laptop and i had ubuntu on it for 3 years. my hard drive started to fail a while ago (i had ubuntu 10 on it until 1 week ago) and a then it all went black...I took the laptop to a repair shop, they told me it was the disc, so i bought a new disc, installed it on my laptop and reinstalled the new ubuntu 11. so far so good. i have now a working OS, internet connection and i can in fact type this message.
The thing is: all my files are on the old drive, which doesn't load/boot/start/read anymore. I have tested it on some friends's pc, tried a few HD disgnostic tools, they all send the same message: "fail"
I then tried to mount my old drive (with all my precious files in it) on my laptop as an external drive (usb) hoping that ubuntu 11 could read it as an external usb key: it gets read by the system, but it shows no files at all. it also shows an error message saying the drive can not be mounted, with some "sdb1" thing. i am sorry but i'm really dumb when it comes to tech language.
Then i tried to boot it on start-up but i got the grub rescue> thing and nothing else, just a sad, blinking cursor to recover my files,i have also tried testdisk but couldn't understand very well how to use it, and then photorec, from which i recovered bits and pieces of files, with no name. some of them are just parts some of them are complete.
My problem is: i have to get access to my files, as I use them for work, i couldn't do a back-up recently and i have some real important deadline to meet... for which i need those files. is there any way i could solve the grub issue and have that drive load/mount again as external usb?

I am running Live 12 on my CD rom drive of my dying laptop. I have a major Windows registry error on that system and am working to recover my files. I have successfully moved a couple of folders from the laptop to my Seagate Free Agent Drive as a test.What I would like to know is, is there a way to copy my files and folders without literally dragging and dropping each one? We're talking 140 G of folders....sigh.

Could any RAID gurus kindly assist me on the following RAID-5 issue?I have an mdadm-created RAID5 array consisting of 4 discs. One of the discs was dropping out, so I decided to replace it. Somehow, this went terribly wrong and I succeeded in marking two of the drives as faulty, and the re-adding them as spare.
Now the array is (logically) no longer able to start:
mdadm: Not enough devices to start the array.Degraded and can't create RAID ,auto stop RAID [md1]
I was able to examine the disks though:
Code:
root@127.0.0.1:/etc# mdadm --examine /dev/sdb2
/dev/sdb2:
Magic : a92b4efc
Version : 00.90.00
code....
Code:
mdadm --create --assume-clean --level=5 --raid-devices=4 /dev/sda2 /dev/sdb2 /dev/sdc2 /dev/sdd2
As I don't want to ruin the maybe small chance I have left to rescue my data, I would like to hear the input of this wise community.

I am trying to create a RAID data drive for my system but I am having setting it up since I am a total linux noob.
The system has 3 physical HDD-s:
1. 320 GB (has functional Ubuntu 9.10 installation) attached to a PCI SATA card
2. 2TB on motherboard
3. 2TB on PCI SATA card
I want to create a software RAID1 of disks 2 and 3. So far I have used the Palimpsest Disk Utility:
- Created a GUID Partition table on both disks (2, 3)
- Used File -> New -> Software Array, made sure both my drives were included
- Once Palimpsest listed the RAID Drive as a Software RAID Array, I told it to create Ext3 filesystem on it
Well.. at least thats what I thought I did. At this point I have been able to mount the RAID drive and put files on it. However when I look at its information in Palimpsest, I am told that the drive is not partitioned. Both RAId components /dev/sda1 and /dev/sdc1 are reported to be in Sync, but the RAID Drive's own state is 'Running, Resyncing @ 45%' (and lowly growing).
My questions are: Is this a normal setup or did I do something incorrectly? Why is the drive reporting to have no partition? And howcome I can use it if it does not have a partition? I have found the command line based configurations to be a tad too confusing to follow, so I have tried to stick to graphical tools - is this a hopeless cause in Ubuntu or is it possible to achieve what I want to do without command line? I will list some info on my disks below - perhaps this offers more insight to those of you more familiar with Linux.
Code:
mindgamer@mind-server:~$ sudo lshw -C disk
[sudo] password for mindgamer:
*-disk:0
description: ATA Disk
product: WDC WD3200BEVT-0

I kept my movies on a 2 drive software raid1 mirror, but now I changed my mind about needing a raid and pulled one of the drives for another use. Can I convert the remaining raid drive back to a regular single drive and keep the data in place? Can I change the raid partition back to regular partition and be able to mount it?

I intend to install ubuntu server 10.04 on an IBM blade server x3550 m3. The server has two SAS and two SATA II hard drives, each configured as RAID 1 through a ServeRAID m1015 card. However, ubuntu didn't recognize any hard drives at the installation.
Is there a way that I can load raid driver (if exists) during installing Ubuntu?

I've just installed ubuntu 10.10 (64bit) on my 1TB drive where as I have my windows drives on a seperate 2x 1TB drives in RAID and am not exactly sure how to mount it.
I am not finding it under computer or under NTFS configuration tool and when I click mount under storage device manager it does nothing, although does detect the RAID array as /dev/sda2

After keeping my old (laptop) computer going for 8 years, I've finally taken the splash and ordered myself a new PC, well the compoents any way to build myself a desktop this time.
I've just got a couple of questions.
I've got a 60GB SDD and a 1TB HDD. On the SDD I was planning on partitions for Ubuntu Swap Window partition, to run a Virtulisation, not dual boot.
Performance wise, is it best to install / on the SDD and /home on the HDD or /home on the SDD as well and just move music and videos ect to the HDD.
Just to complicate things, when ordering the HDD there was an offer to get a second 1TB HDD for an extra 11, so now I have 2. I was planning to set these up as RAID 1, which I believe I can do via the alternative install.
What would be the best way to then backup / . I guess it must be possible to schedule an image of/ to be copied across to HDD is it?
I did hear that RAID was a bit iffy in ubuntu, but looking about on the net things seem to be better 9.10 → Also the boot disk isn't RAID.
Are there any RAID or SSD issues I should be aware of?

I ran into this and found a non-trivial solution so I thought I'd share in case anyone else ran into it.I have two 200GB drives so I thought I'd install my system with RAIDed partitions for /boot, / and /home. I would use RAID1 for /boot and /home because GRUB2 can load the kernel from a RAID1 and I thought the extra reliability for /home would be nice. (I may second guess /home on RAID1 once I get to test performance.) I chose RAID0 for / to provide faster application loading.I prepared the drives using a Live CD because I'm not confident that I can do what needs to be done during installation.First I partitioned the drives as:
Code:
hbarta@olive:~$ sudo fdisk -luc /dev/sda
Disk /dev/sda: 200.0 GB, 200049647616 bytes
255 heads, 63 sectors/track, 24321 cylinders, total 390721968 sectors
Units = sectors of 1 * 512 = 512 bytes
[code]....
At this point I could restart and boot from the system hard drives and proceed with configuring my system. I'm not positive that it is necessary to add the modules to /etc/initramfs-tools/modules but I do know that alone is not sufficient. An earlier attempt was to install grub (install-grub /dev/sda; install-grub /dev/sdb) within the chroot and I found that also was not sufficient. I have not listed it above because I think it was not necessary. But on these two issues, I'm not going to reinstall again from scratch just try...
[URL]
Another possibility is to install using the Alternate CD. I did not try that but it may provide better RAID handling. Last week I installed 10.04.2 LTS Server to a RAID1 and it did not experience this problem. However I do not know if it is RAID in general or RAID0 that led to the issues I encountered.
