Logical Volume Problems...

[Denton Williams]

Hi All,
I am having some problem with one of my LV's and it is showing this error:

vxfs mount: /dev/vg00/lvol5 is corrupted. needs checking

I might have forgotten to mount before I rebooted the system. Can anyone show me what my options are? any help will be greatly appreciated.

Denton.

Hi,

Try this:

# fsck -o full /dev/vg00/lvol5

This will do a complete check on the file system and will fix it if there is no hardware errors. You may mount the file system after that.

I tried the command you gave me but it gave me the following error:

fsck -o full /dev/vg00/lvol5
vxfs fsck: file system had I/O error(s) on meta-data.
vxfs fsck: file system had I/O error(s) on user data.

Thanks,
Denton.

I start with

fsck -F vxfs /dev/vg00/lvol5

This just fixes the superblock as clean.
That is normally what is needed when you reboot with out a normal shutdown.

What do you get when you do a lvdisplay -v /dev/vg00/lvol5 ? Is it possible that the drive is bad?

Hi Denton,

Your file system has hardware errors on it. You need to replace the disks. Find out the disks on this file system:

# lvdisplay -v /dev/vg00/lvol5

Contact your hardware support and get it replaced. After replacing the disk, do a 'vgcfgrestore' on the new disk. That will restore the original VG information to the new disks. Then create new file system (newfs) and restore your data from the backup.
