 Linux – Check disk status
Linux
Hi, I need to know how to check for disk errors on Linux, similar to the Solaris iostat -E command. Thanks, JCD.

fsck -A will check all filesystems in the /etc/fstab file. Check the manpage for your Linux brand. Don

First mount your hd to read-only.
secondly, if you are use ext3/ext2, e2fsck /dev/hda, if you are using reiser, then use the reiserfsck command

I don’t think this is what the poster is asking for. Solaris iostat gives output similar to:
solaris9-test% iostat -E
sd0 Soft Errors: 0 Hard Errors: 0 Transport Errors: 0
Vendor: IBM Product: DDYS-T36950M Revision: S80D Serial No:
Size: 36.70GB
Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0
Illegal Request: 0 Predictive Failure Analysis: 0
sd1 Soft Errors: 0 Hard Errors: 0 Transport Errors: 0
Vendor: IBM Product: DDYS-T36950M Revision: S80D Serial No:
Size: 36.70GB
Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0
which reports disk-level errors. fsck runs a filesystem level check, and does not report disk errors.

There’s a sysstat package that can be downloaded that contains iostat for Linux: http://perso.wanadoo.fr/sebastien.godard/

Outside of gathering this info from /proc/partitions and /proc/stat, it’s probably your best option.

Thanks, Swiftd. It looks like that package still lacks the crucial ‘-e’ flag to report disk errors. I posted this questing back in April and received similar results – I just don’t think Linux has a way to report disk errors. It seems filesystem errors are as far as we can go.

For S.M.A.R.T. Hard drives, there’s Smart support.

It’s probably not what you are looking for, but it does provide a lot of information.
