[Hans-Gunther Borrmann]

Hello all,

during the migration from TRANSARC fileservers to OpenAFS namei fileservers I 
ran into major problems. One is now:

I cannot replicat a volume:

Volume needs to be salvaged
Error in vos release command.
Volume needs to be salvaged

The FileLog:

Wed Jan 26 17:23:08 2005 VAttachVolume: Error reading smallVnode vol header /
vicepcf//V0537069092.vl; error=101
Wed Jan 26 17:23:08 2005 VAttachVolume: Error attaching volume /vicepcf//
V0537069092.vl; volume needs salvage; error=101

A salvage does not help.
I did vos remsite ... which works. And then I tried "vos zap -force" of 
537069092. This command loops forever and volser produces one core dump after 
the other.

Any help is appreciated.

Operating system AIX 5.1
OpenAFS: openafs-snap-2005-01-17
