I was wondering if anyone out there has noticed a bug that we've been
experiencing since we went to AFS 3.1:
For some reason, many of our backup volumes don't seem to exist. They
are there according to the vldb, but they aren't really there. Vos
listvol knows nothing about them. This wouldn't really be a big deal,
except that when we run vos backupsys, it says "Creating backup volume...",
but never does create the volume. The message about Re-cloning the volume
never shows up. The only way to bring the volume back is to explicitly
remove the .backup volume. You then get a warning about the volume not
being on the disk.
All of our servers are either rt_aos4 or rs_aix31 systems...
This hasn't been a big deal in the past because we were using my own
home-grown back system which died when it couldn't dump a volume. Now
we're using y'all's backup system, which skips volumes it can't find.
The end-result is we're not getting volumes backed up that we thought
we were.
I don't know why the backup volumes are disappearing -- I suppose if
there's a bug in AFS causing that it would be good have a fix. What's
also needed to really fix this is for "vos backupsys" to notice that
there's no existing backup volume even though the vldb says there is
one, and to build one from scratch.
