Hello Managers,
The following AdvFS exception reared its ugly head on one of our
systems today. The system will come up in multiuser mode for a few
minutes then panic. I found in the archives a reference to an identical
problem described in Dec 1997 in which the poster indicates a resolution
that involved removing the fileset and restoring from backup to the same
location. He was seeking clarification on possible causes and alternative
ways of handling, but there was never a summary. Is the approach he took
the best one and am I correct in interpreting this error to mean that the
filesystem is corrupted but the media is likely okay?
The system in question is an AlphaStation 500 5/333 running DU 4.0B at
Patch Level 6.
Thanks much.
