[OpenAFS] OpenAFS Backup Trouble (volume loss) on SuSE Linux 7.3 / Kernel 2.4.18

Ok - the following entries look interesting (to me, that is;-)):

Mon Apr 22 01:07:02 2002 CB: RCallBackConnectBack (host.c) failed for 
host 213.178.69.42:7001
Mon Apr 22 09:02:27 2002 CopyOnWrite failed: volume 536871180 in 
partition /vicepa  (tried reading 8192, read 0, wrote 0, errno 2) volume 
needs salvage

The first host mentioned (69.42) was most probably offline during that 
time.
The second is the CopyOnWrite message.

Neither of the two occurs during backup though. Backup is running from 
22:55 to 23:55 (approx.)

Best regards,
and thank you,
Carsten
