Fix Corrupted Veritas Filesystem VXFS

A Vertitas filesystem can sometimes become corrupted. This specially happens when your replicating a filesystem. So how do you fix that !? Well lets begin.

Say your importing a  diskgroup called app-dg

vxdg import app-dg

#VxVM vxdg ERROR V-5-1-10978 Disk group app-dg: import failed:
Disk is in use by another host

Now lets list all the disk groups on the system

vxdisk -o alldgs list

So how do you fix it ? You have to clear the host ID attached with that disk group

vxdg -f -C import app-dg

vxvol -g app-dg startall

Now lets mount it

mount /local/zones/app/appmount
UX:vxfs mount: ERROR: V-3-21268: /dev/vx/dsk/app-dg/appmount  is corrupted. needs checking.

Oops so now we begin the real fixing.

fsck -F vxfs -o full /dev/vx/dsk/app-dg/appmount
log replay in progress
pass0 – checking structural files
pass1 – checking inode sanity and blocks
pass2 – checking directory linkage
pass3 – checking reference counts
pass4 – checking resource maps
OK to clear log? (ynq)y
flush fileset headers? (ynq)y
set state to CLEAN? (ynq)y

Now you have repaired the file system now mount it again

mount /local/zones/app/appmount

And voila ! 😉
