We have a strange intermittent problem doing AFS backups ever since
we moved to AFS 3.6. Has anyone else experienced this problem?
Any input would be appreciated.
We do backups from our Sun E250's to Sun standalone DLT 7000 tape
drives. We are running Solaris 2.7 with AFS Base configuration
"afs3.6 2.3".
Our full backups require 2 tapes. The first tape always completes
fine. The second tape always continues fine. But, sometimes the second
tape "freezes". That is the backups stop running on the second tape.
There are no messages in the butc window, we run butc
with a debug level of 1. There are no messages in the
/usr/afs/backup/TE_rmt_0u or TL_rmt_0u logs. There are no messages on
the console or the system log /var/adm/messages. The only clue is
in the backup prompt:
backup> status
Task 1: Dump: 11033914 Kbytes transferred, volume
D1.prj.stm.da.gt.nM.fi.backup
Task 2: Dump: [drive wait]
We start the entire dump over and it usually works the next time.
I realize there is a new AFS 3.6 patch release. I read the
readme.txt and it did not indicate a fix for this. Any ideas?
