The VxFS Admin Guide has more details on the OLT and the importance it
plays.

acceptfsck command
Hi All,
In my original email I used the block device for my fsck command instead
of the raw device. I would just like to clarify that when I use the raw
device I get the same error.
# fsck -o full -F vxfs /dev/vx/rdsk/dg-ovpidb/vol-ovpidb-data
UX:vxfs fsck: ERROR: V-3-20729: OLT extents conflict
read of primary OLT failed
UX:vxfs fsck: ERROR: V-3-20727: OLT extent 1 has bad magic
read of OLT copy failed
UX:vxfs fsck: ERROR: V-3-20718: no valid OLT, cannot continue
file system check failure, aborting ...
Regards,
Rick

Subject: Help ... vx volume is corrupted and doesn't accept fsck command
Hi All,
One of my VX volumes is unable to mount. When I try to mount the volume
I get:
# mount -F vxfs /dev/vx/dsk/dg-ovpidb/vol-ovpidb-data /mnt
UX:vxfs mount: ERROR: V-3-21268: /dev/vx/dsk/dg-ovpidb/vol-ovpidb-data
is corrupted. needs checking
If I do a fsck on the volume I get:
# fsck -o full -F vxfs /dev/vx/dsk/dg-ovpidb/vol-ovpidb-data
UX:vxfs fsck: ERROR: V-3-20729: OLT extents conflict
read of primary OLT failed
UX:vxfs fsck: ERROR: V-3-20727: OLT extent 1 has bad magic
read of OLT copy failed
UX:vxfs fsck: ERROR: V-3-20718: no valid OLT, cannot continue
file system check failure, aborting ...
Is this error terminal or is there a way that I can recover the volume
so that it can be mounted?
The state of the volume and plex is ACTIVE ENABLED
v vol-ovpidb-data - ENABLED ACTIVE 134217728 SELECT
ovpidb-data-01 fsgen
pl ovpidb-data-01 vol-ovpidb-data ENABLED ACTIVE 134217728 STRIPE 2/128
RW
sd dg-ovpidb01-01 ovpidb-data-01 dg-ovpidb01 0 67108864 0/0

sd dg-ovpidb03-01 ovpidb-data-01 dg-ovpidb03 0 67108864 1/0
SUN35100_17 ENA
Any help would be greatly appreciated.
Thanks,
Rick
