Hi All,
I was just wandering if the issue that affects NFS availability when
deleting large snapshots on ZFS data sets with dedup enabled was fixed.
There is a fix for this in b141 of the OpenSolaris source product. We
are looking at including this fix in a forthcoming patch update/micro
update to the Nexenta product. So stay tuned for more on that.

I have similar problem - when destroying snapshot (few gigabytes in
size) on ZFS data set with dedup enabled (was enabled prior and at a
time when snapshot was taken, but disabled later) NFS hangs and
becomes unavailable to remote hosts (same gigabit LAN).
I have a decent hardware with quad core Intel Nehalem CPU, 12 GB RAM
and Intel SSD drives as read and write cache for this zfs pool
configured. I'm running Nexenta Community edition 3.0.1.
I've posted to Nexenta community support forum but they referred me to
OpenSolaris community mailing list or as they've explained it's not
Nexenta, but rather OpenSolaris issue.
Thanks,
Dmitry
