Thanks for the reply but this seems to be a bit different.
a couple of things I failed to mention;
1) this is a secondary pool and not the root pool.
2) the snapshot are trimmed to only keep 80 or so.
The system boots and runs fine. It's just an issue for this secondary pool
and filesystem.
Hello all,
I have a situation where zpool status shows no known data errors but all
processes on a specific filesystem are hung. This has happened 2 times before
since we installed Opensolaris 2009.06 snv_111b. For instance there are two
files systems in this pool 'zfs get all' on one fil
s as the
zfs send stream. It does not verify the ZFS format/integrity of the
stream - the only way to do that is to zfs recv the stream into ZFS.
