Hardware :: Raid6: Disk Failure On Sdb1, Disabling Device?
Jun 9, 2010
For backup purposes, I built a RAID6 array on USB. When during the night the backup filesystem is being mounted, every so many days, a random disk fails:
Code: sd 9:0:0:0: [sdb] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE
sd 9:0:0:0: [sdb] Sense Key : Illegal Request [current]
sd 9:0:0:0: [sdb] Add. Sense: Invalid field in cdb[code].....
In other words, my RAID set fails every so many mounts, but I know how to fix it.What I want to find out is:
- Why is a random drive failed every now and then?
- How can I prevent that drive from being failed?
BTW: I have a second RAID set that has been functioning for years without error, so the setup I use must be correct. The only difference between both RAID arrays is the different vendor of the disks.

I rebooted my server and out of nowhere the RAID5 array won't assemble. I've tried everything I could think of to reassemble the thing. I fear that the array is ruined, but I can't imagine how. Here are various bits of information: The simplest failure (with and without partition numbers, which have not been needed in the past):
Code:
richard@nas:~$ sudo mdadm --assemble --verbose /dev/md0 /dev/sd[bcd]
mdadm: looking for devices for /dev/md0
mdadm: cannot open device /dev/sdb: Device or resource busy

I have an external usb disk connected to a Debian desktop. A couple of days ago these messages started appearing in dmesg
Code:

When this appears the disk becomes unavailable and I have to remove and plug it in and mount again. After that it works couple of hour and then the problem appears again. Is this a hardware problem?

I installed 10.04 on a new machine and 'tried' to create a 4 disk RAID6 array on four new 4TB drives.The build seemed to go fine, but a check on the new dev shows the following:

I have set up a server box running Ubuntu 10.04 Server 64-bit with Squeezeboxserver, ftp, apache and all the things that I need.I am running it on a Asus P5Q pro with 9 harddrives attached.I have set up 6 1tb disks that run a raid6 array but I am wondering what would happen if the motherboard would fail me.Is it possible to just replace the motherboard with a newer one and would then the raid6 array still be intact?
I used to run a raid10 with the 6 disks on a Windows 7 machine with a software raid card but the card broke and I replaced it with a new one but the array could would not work so I had to forget all my data and this is what brought me to using a Ubuntu server as OS and running the raid array on the motherboard sata instead.Also, is it possible to make an exact copy of the boot drive/partition and easily replace that is the boot hard drive would go faulty? I have heard about the dd command and I feel it would be nice to know that I'm not totally screwed if the boot drive fails.

As per [URL] I built a RAID6 array. yay. In the end it completed.
Code:
fermulator@fermmy-server:~$ cat /proc/mdstat
Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10]
md2000 : active raid6 sdo1[3] sdn1[2] sdm1[1] sdl1[0]
3907026944 blocks level 6, 64k chunk, algorithm 2 [4/4] [UUUU]
To test stability, I rebooted the system, but on reboot, the array wasn't assembled correctly. Basically it had one device in "md_d2000", as a spare. So I stopped that device with
Code:
sudo mdadm --stop /dev/md_d2000
The superblocks looked good ...
Code:
fermulator@fermmy-server:~$ sudo mdadm -E /dev/sd[lmno]
/dev/sdl:
Magic : a92b4efc
Version : 00.90.00
[code]...
I don't have any important data on the array yet ... so I zero'd the superblocks on all devices, deleted the partitions, and started over .. here I go again:
Code:
md2000 : active raid6 sdo1[3] sdn1[2] sdm1[1] sdl1[0]
3907026944 blocks level 6, 64k chunk, algorithm 2 [4/4] [UUUU]

I have a USB which I would like to make the device boot able. I have looked into fdisk and it appears that using fdisk I can only set a partition to a boot able. Please have a look at the output of fdisk command. In the following the sdb1 and sdc1 are both USB Memory Stick. As you can see the sdc1 is set as boot but the sdb1 is not.
Code: Disk /dev/sda: 80.0 GB, 80026361856 bytes

Units = cylinders of 16065 * 512 = 8225280 bytes

I have 10.10 installed and working OK. The Home directory is located on a second 1TB disk (sdb1). Recently, I've started to experience random boot failures where the start-up routine gets as far as showing the '10.10' logo with the progress dots underneath, but then throws up an error message saying that it cannot mount sdb1. I then have an option to Quit or drop into the shell to do a manual restart.
If I then do a Ctrl/Alt/Del, the system reboots, but usually fails again. Powering off and on, sometimes more than once, is the only way to eventually get a clean boot. The drive causing the problem is fairly new and all the diagnostic checks seem to indicate that it's healthy, so I'm not sure what causes the problem.

The external hard drive which contains all my photos and where I backed-up all my important documents is no longer recognized. It is a three month old 500GB Iomage Prestige Desktop Hard Drive.When I plug it in, it is recognised as a USB device, because it shows up when I type lsusb, but dmesg gives this error message.

I popped the disk out of the casing put it on a SATA connect internally and then tried the file recovery programs testdisk/photorec and SpinRite, but both failed because they couldn't recognize the external hard disk.

my Fedora 11 system is not starting anylonger. It stops with the message:
Code:
VFS: Can't find ext4 filesystem on dev dm-0
The system told me since a while, that a lot of the sectors of one disk of the (software) RAID compound are failed already. So tried to disconnect each of the disks and start them separately. Unfortunaltly this is not working (for one its is not working at all, the other wents the same far as with both), when I tried to recover the system with the Fedora DVD, it said no distribution found. I am quite new and do not know so much about linux system, so i do not know what further information you could need. Maybe it can be important, that both disks are encryped (the system wents so far, that I can type in the password).

I was using Terminal and browsing a directory in my home folder. My "home" directory is located on "/dev/sdb1". When in Terminal I typed "ls" in one of my directories and the output was garbage. The output didn't show the files in the directory. I think it said something like, "input/output error". Unfortunately, I didn't write the exact error down. Instead I rebooted.The hard disk with the problem is:

My laptop has an internal wireless device and a button to turn it on/off, but since it has bad reception I use an external USB wireless adapter.The problem is that if I turn the internal wireless device off using the button, it also turns the USB wireless adapter off.Is there anyway to use the killswitch (the button) only for the internal wireless device?This only started to happen in Ubuntu 10.04.

I installed from a live disc months ago. It worked fine for a while, don't remember what caused the change.
Now when I boot, I get this message:
Quote:
I have several hdds in this desktop box, one other has a OS on it, has the Hardy version. But i disconnected that (it all used to work with both drives connected and I was able to use that boot menu to change from one OS to the other). I can boot by getting to "boot menu" by pushing the "esc" key when the bios starts (just after the beep). It gives the option to start from, with a list of possible devices to choose from. I don't know where this menu is from, bios or other. I select hard drive, then select the correct hard drive and it starts right up. That is nonsense though. I really no longer need version 8.04 but keep it as a backup in case my preferred OS/hdd fails.

2 weeks ago, my power supply blew, during close-down. My system is a SUSE Linux 10.1 and openSUSE 11.1 dual boot with WInXP (for those family things). After replacing the power supply my system had no root partition, or loader. It said something like "Invalid Partition table". Grub had gone! So following swerdna's "How to Boot into openSUSE" tutorial I used the openSuse 11.1 install CD rescue option to get to the command prompt, su'd, went to grub and followed the stated commands. So far so good.
However the new grub entry openSUSE (Failsafe) has a problem. It starts to boot in the usual way, but I note fatal Module errors in the boot log relating to sata_nv not found, ide_pci_generic not found etc, and Fatal error inserting edd (/lib/modules/2.6.27.39-0.2-default/kernel/driver/firmware/edd.ko): no such device but uses udev as boot source until Waiting for device /dev/disk/by-id/ataST3120827AS-4M60PX7V-part6...... and then it exits to /bin/sh.

Recently installed some minor software, some games and Ubuntu Tweak, I am not sure if that's what caused this issue or not. I shutdown after the installations, then when I tried to start back up the small, white ubuntu logo appears just like it normally does, then it just goes to a black screen. I turned off the computer and restarted in (Recovery Mode). It goes about its thing then it says it is waiting for root file system, then after about 30 seconds it says "Gave up waiting for Root File System" how to fix this without reinstalling?

I'm a long time Linux user. Finally got around to upgrading my Fedora 11 system to Fedora 12 by using the 'preupgrade' tool. The upgrade appeared to go well (downloaded packages, rebooted into installer, etc). However, now that the upgrade is complete, I'm unable to boot my system.
Here's my configuration:
/dev/sda (80Gb)
200Mb /boot partition (ext3)
52Gb / partition (ext4 - managed as logical volume)
2Gb swap partition (managed as logical volume)
20Gb /spare partition (ext3 - managed as logical volume) .....
All worked fine under Fedora 11 for the last few months. Grub now presents me with 'Fedora' and 'Windows XP' boot options. The /boot/grub/menu.lst file is essentially the same as it was for Fedora 11, except for the different kernel versions, etc. The boot sequence shows the Fedora bubble (??) and gets about 80% full when the screen goes black and the message displayed is:
No root device found
Boot has failed, sleeping forever
If I boot Windows, all works fine.
Am able to boot using a SystemRescueCD disk. The disks all look okay and I can mount/modify all partitions, etc. The grub menu.lst file read as follows (sorry, typed in, not copied):
default=0
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title Fedora (2.6.32.11-99.fc12.i686.PAE)
root (hd0,0) .....

Ubuntu/Linux operating systems. It installs just fine but after it reboots I get a "disk boot failure, insert system disk". I have searched around but I can't seem to find anything that works. There is only one hard drive in my computer and no other operating systems on it.

While using my computer the other day (I was sending an email) it suddenly turned off. I didn't get any low power warning, but I was running on battery and had my iphone charging from a USB port.
As I didn't think there was low battery, I just turned it back on again. As it was booting I saw the battery light flashing, indicating low power. I went to get the charger, but before I got it, mid boot-up it turned off again.
This seemingly damaged something hard-disk-wise.
Upon turning it on again it dropped into busy box with some message similar to this:
Quote:
No init fount. Try passing init= bootarg.
BusyBox v1.13.3 (Ubuntu 1:1.13.3-1ubuntu7) built in shell (ash) Enter 'help' for a list of build in commands
(initramfs)
That's not the actual message (copy pasted from another post) but the message is VERY similar to that.
If I "exit" busy box, I get a load of message about "kernel panic" before it freezes up.
I have booted a live USB (what I am using now). I thought since it wasn't cleanly unmounted, simply mounting and unmounting would do the trick. I was wrong.
Code:
ubuntu@ubuntu:~$ sudo fdisk -l
Disk /dev/sda: 250.1 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
[Code].....
I had previously ran e2fsck (after checking it was unmounted) but it wouldn't run also because it was reporting that the device was already mounted, busy, or being exclusively used by a process.
I don't want to do any more for fear of causing further damage.
I am astounded that such damage can be caused so easily!

Here are my specs to start off...
OS: Corrupted Windows XP, Home Edition
CPU: Pentium 4 2.8GHz
RAM: 1gb
Graphic Card: nVidia GeForce 8600 GS
So I corrupted my Windows OS by doing something stupid so I decided to install Unbuntu. I tried installing it over my windows OS, but as it's scanning the disk it fails and says "Apt configuration failure" and then "installation failure". I can't upload my partitions because I can't run my OS to find them.
I know the information is limited I've considered trying to install a different linux OS or even format my entire harddrive (I would really prefer NOT to do that since I'd have to install all the drivers off the internet).

Following scenario: My server in some data center on a different continent with two disks and software raid 1.
One day I see that a disk failed (for example with /proc/mdstat). Of course I should replace the failed disk asap. Now that I think about it, I am not sure how. What should my email to the data center support guy mention to make sure that guy doesn't replace the wrong disk?
With hardware RAID it is very easy, because the controller usually has some kind of red LED indicator. But what about software raid?

I initially thought the problem had to do with the Lucid Lynx upgrade, a lot of people have been reporting similar issues with drive mapping and things along those line. My issue is that an external drive, formatted in FAT32 appears to be corrupted, and overtime begins to read or mounts as 'read-only.'
What I've read, and deduced, is that this is ultimately and issue with the drive. I've backed it up, reformatted, and been able to write to the drive successfully, but I've been moving a lot of files (backing up) and the system has been reporting input/output errors in transferring some files (through the GUI).
The only thing I can think of, is that the device itself is corrupted or damaged, and that I need to be thinking of other back-up options for the future. Any suggestions on disk-doctoring? I'm hoping to do a clean-install of the OS once I back up my files manually.
