I want to use smartd for monitoring my hard disk regularly. What is the interaction of smartd with the hard disk driver that is in use. Whether the hard disk driver should be smart enabled or only the hard disk. Will any one help me in this.
View 6 Replies2 months ago, I built a dedicated backup server using 4 2TB SATA drives for software RAID5 (6TB total). A few days ago, smartd sent out mail saying it found an unreadable sector on one of the drives. I ran selftest using smartctl and the error persisted. So far, neither software RAID nor ext4fs running on top of the RAID volume have reported errors.
MOST OPTIMISTIC: It is normal to have a few bad sectors among billions. Software RAID takes care of alternatives. Keep using the system until RAID spits a more serious warning in the future.
MOST PESSIMISTIC: It is a really bad sign to lead a disaster. No good disk drive should have bad sectors especially when it is only 2 months old. The error is simply not detected by software RAID and ext4. Replace the drive immediately and return the bad drive to the supplier.
I had a dual boot (windows 7 + debian), both of them installed in my internal hard disk, with the GRUB in it. I have recently installed a second linux distro (mint), but I put it in an external hard disk. Now the GRUB allows me to boot any of the three operating systems, but I need the external disk to do it. It seems that after the mint installation the GRUB is now working from the external disk (if the external disk is not connected, the machine does not boot.) �Is there a way to change the location of the GRUB, to the internal hard disk of my laptop?
View 2 Replies View RelatedIf you have a hard disk image (including partition table, multiple partitions,...), is it possible to let Linux treat it as a regular hard disk?
By "regular hard disk" I mean I would like to have the image show up as, for instance, /dev/hdx and its partitions as /dev/hdx1,...
(I know I can mount one of the partitions in the image using "mount -o loop,offset=x ..." but I don't really like this option.)
I've been given an old blue and white Macintosh G3 350MHz 700MB RAM and 6GB HDD. When I try to install Ubuntu Server 9.10 PowerPC the installer tells me it cannot see a HDD and that I have to select a Driver for the Disk. I have absolutely no idea which driver to pick from the very long list.

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:

View 14 Replies View RelatedI decided I needed to expand my openSUSE partition because I was running out of room. There was some unallocated space following my /home and swap partitions that I wanted to assign to my / partition.
So after taking note that bad things could happen (as I've read everywhere), I got myself a copy of GParted (since Yast! partitioner doesn't move partitions, does it?) to start getting the thing to work. Well, actually, I got PartedMagic which has GParted (I realize it could be a problem NOW if they didn't have the latest version).
So the first step was to move the swap partition. I decided to do it one step at a time and only moved the swap partition to the end. That turned out fine...no problems whatsoever.
The next step is where the problem came in. It was moving the /home partition. It took a while to move but once it got to the end, it showed a message that was similar in nature to "error detected" without giving a long list of error messages. If it did, I probably would have copied it down. There wasn't anything in the "logs" either in GParted besides what it showed. Looking back, I probably should've went into /vars/logs to get additional log information but I guess I wasn't smart enough to do so (provided that GParted does leave log messages there which I think it does).
After that, it refreshed the drive and it ended up showing no partitions with an error and saying the only thing it can do is create a new partition table. After that, openSUSE wouldn't boot. After loading, (both normal and failsafe modes) it gives me the message in the link at the bottom. I can still access those partitions fine. Nothing's corrupted. Windows also boots up fine (it's on a different drive though) and reads the affected drive fine. Linux-based LiveCDs (including openSUSE 11.3) reads the partitions fine too.
I've tried using e2fsck on my ext4 partitions with commands I found during a search and they seemed to "fix" those partitions but it still won't boot and gives me the same message. Looking at it carefully, it seems the reason it can't find a superblock is because it can't find part8 of whatever that thing under /dev/disk/by-id/ is.
I would very much prefer a failsafe (or at least mostly failsafe) solution that won't (or is unlikely) to result in requiring the restoration of a backup but I do understand that there is always the chance of something going wrong that will kill everything. Considering that I can still access the data on that drive, I don't believe the data is corrupted. Maybe the drive itself (as in whatever signatures it may leave) but not the filesystems.
This is what I end up with trying to boot into openSUSE (sorry, I don't know how to get the log when it doesn't put it in logs directory: https://docs.google.com/leaf?id=0B3A...ut=list&num=50

I want to make the transition from windows (sick of it). Im using Lenovo G530 Laptop and was wondering which would be the best Linux Os (meaning Ubuntu, fedora or something else). Keep in mind that I mostly use my laptop for college work and a lot of video and audio editing. I also want to be able to run Dual operating system (meaning that I wanna run both Linux and Windows) from the same computer as it might be easier for me to make the transition a little bit more easier. That being said I need someone to give me tutorials (video preferred) on how to make the partitions on the hard disk and step by step instruction on how to install both the two OS in my laptop.

The problem is using 'dd' the image is too big ( I have 1tb drives ) and then I am not sure how to convert these images back on to new drives so that they boot in the OS as well. i am not sure if there is a utility that would let you do that?
View 2 Replies View RelatedI have 2 IDE drives, Windows XP is on the Master drive & Fedora 12 is on a partition the other drive. I purposely installed the Linux boot loader on the same drive as Fedora because want to use NTLDR as the primary boot loader. According to a guide I found [URL], I should be able to copy the Linux boot sector to a file & put that copy on the Windows drive & then modify boot.ini, so I am prompted to with an OS choice a startup.
The problem is the command the guide gives to copy the Linux boot sector (dd if=/dev/hdb1 of=bootsect.lnx size=512 count=1) has outdated syntax and does not work. What syntax would make this command work in Fedora 12? Another guide I found ([URL]-vista-already) suggested using: Grub4Dos & modifying boot.ini. This method almost worked until grub gave an error that there was no kernel loaded. What would I type into the grub prompt to load the kernel? How would I automate the loading of the kernel, so I don't have to specify the kernel each time?
I am developing a program which can access the SATA-hard disk. I have to use the /dev/sda interface for accessing the hard disk. What are all the commands i can use to perform the sector read, write (Both DMA and PIO), sending the smart commands etc. Or is there any easier way?
I saw that i can make use of hdparm call for getting some of the attributes.
