As part of my nightly backups, I clonefset each advfs filesystem, mount
the clone, vdump the clone, unmount the clone, then rmfset the clone.
After "upgrading" from 4.0B to 4.0D (patch kit 2:
DUV40DAS00002-19980717), we noticed that the cloned fileset is
inaccessible when a clone is being removed. In fact, this is a fairly
busy NFS server and when a clone is being removed, even NFS requests
for filesytems not involved in the clone removal hang until the rmfset
completes. Over the last year, our storage requirements have grown
much larger (making the clone removal take much longer) and this
problem has grown from being merely annoying to becoming nearly
unacceptable.
Other than this behavior (and the NFSv3 dupreq problem) this version
of DU has been reasonably stable. Before I blindly attempt an upgrade
(to either the latest jumbo patch kit for 4.0d, or to the latest patch
revs of 4.0e or 4.0f), I was hoping somebody could tell me which
versions of DU this problem does not affect.
Thanks in advance,
Drew
