vxfs mount: /dev/vg00/lvol6 is corrupted

[Achilles_2]

Hello there,

After I reboot the A900 HP server, the /opt parition couldn't auto mount. And it shows the error :

Mount file systems
Output from "/sbin/rc1.d/S100localmount start":
----------------------------
mountall: cannot mount /dev/vg00/lvol6
mountall: diagnostics from mount
vxfs mount: /dev/vg00/lvol6 is corrupted. needs checking
checking quotas

Do anyone explain why and how to fix?

Thanks

hi,

basically, could be your system not properly shutdown ..

just perform fsck -y it will do the fix and mountall.

#fsck -y
#mountall

No, the server is normal shutdown without any error. And I tried your given method but it has the same result

# fsck -y

fsck -y /dev/vg00/lvol6

If the o/p is same, you can try running same in single user mode.

Hi,

What is the version of OS ?
What is the size of the filesystem, i mean the exact size ??

Try this command..

fsck -F vxfs -o full -y /dev/vg00/lvol6
mount -F vxfs /dev/vg00/lvol6 /

Best Regards,

It got the same error message and /opt couldn't mount.

It uses HP 11.00 and the size of /opt filesystem is ~4000M.

fsck CANNOT fix a broken disk. The word I/O error means that data needed by fsck to make sense out of the directory structures is not available or corrupt. The disk is indeed toast and will have to be replaced. If the data is very important, There are several companies that specialize in data recovery but make absolutely sure they can handle HP-UX disks.

Sounds like a bad disk to me. Try running diskinfo and dd against it:

diskinfo /dev/rdsk/

dd if=/dev/rdsk/ of=/dev/null bs=1024k

If any of this fails or gives error then it is sure that disk is faulty and needs replacement.
