drive corrupt - should I ask for new drive or reimage?
| Posted by MrShoop, 07-09-2007, 05:52 PM |
| I have a dedicated box and I started getting Input/output errors today.
I tried:
# fsck
fsck 1.40-WIP (14-Nov-2006)
e2fsck 1.40-WIP (14-Nov-2006)
/dev/hda2: recovering journal
fsck.ext3: unable to set superblock flags on /dev/hda2
then I tried:
# fsck -a -t ext3 /dev/hda2
fsck 1.40-WIP (14-Nov-2006)
/dev/hda2: recovering journal
fsck.ext3: unable to set superblock flags on /dev/hda2
My data is backed up, so was going to ask for a reimage, but is this an indication of bad hardware? Should I ask for a replacement drive? Is there anything else I should try on my own before going to the host?
Thanks!

| Hi,
First of all Input/Output errors can not be recovered using fsck
Second, you should never run fsck on a mounted filesystem, you will damage it
Yes, you need a replacement drive

| The superblock contains information that is global to the entire filesystem, such as the total number of blocks, and the time of the last mount.
You should contact your DC to run fsck, as it is not supposed to run on a mounted drive.

| If you can get it, of course ask for a new drive. At least, if it does not get replaced and you have a failure soon after, you will be on record as having asked for it.

| Other than that, are they any other ways to check if a hard drive is having bad sectors?

| why do you need more ways?

| unmount /dev/hda2
The command dumpe2fs will give you list of super blocks
dumpe2fs /dev/hda2 |grep superblock
try a superblock number from this
e2fsck -b /dev/hda2
