[Veritas-vx] filesystem corrupted by NBU restore

Hi George,
 
It looks like something has gone wrong during the restore - possibly
hardware, possibly software related.  The reason that you had the problems
with the filesystem is as follows:-
 
Sep  3 04:32:28 prod2 unix: WARNING: msgcnt 34233 vxfs: mesg 037:
vx_metaioerr - vx_tran_dircompact:1 - /dev/vx/dsk/prod2dg/uat5 file system
meta data write

Sep  3 04:32:28 prod2 unix:  error in block 1988784

Sep  3 04:32:29 prod2 unix: WARNING: msgcnt 34234 vxfs: mesg 031: vx_disable
- /dev/vx/dsk/prod2dg/uat5 file system disabled

 
The filesystem experienced a write error to the metadata and as such
disabled the filesystem, anytime a filesystem gets a write error to the
metadata (filesystem structure) it will be disabled.
 
I would suggest that you open a case with VERITAS support and have this
investigated - may be too late now, but they may find something.
 
BTW, for future reference if a filesystem is disabled it will not require a
reboot, just to be umounted, fsck'd and remounted.  I would also strongly
suggest that if your filesystem requires a full fsck (with metadata write
errors this is generally the case) then you should open a support case
before running it as in a worst case a full fsck can result in loss of all
files.  VERITAS support will be able to walk you through it in the safest
way possible
 
DISCLAIMER: BUT be aware it is highly recommended that you have a full
backup to fall back on because as good as support is they can not (always
;-) work miracles.
 
Regards,
Duncan

Subject: [Veritas-vx] filesystem corrupted by NBU restore



Dear friends,

I had an issue with a filesystem, /uat5 which was restored, by an user,
using Veritas NetBackup 4.5 while some of the files in it were open by
processes owned by the same user.

What happened is that besides the filesystem has overflowed, it also became
corrupted in such a way thay it could not be "cd" into it, could not be
unmounted, etc. when running "df" was displaying I/O error, etc. The
underlaying volume was started all the time.

The only way to clear the error was to reboot the whole server, after which
the filesystem came clean without any fsck.

While it is normal to expect problems when restoring over open files, is
there a way to clear such error without rebooting the server ?

The filesystem is VXFS 3.5.
