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. More on the issue here: http://www.mail-archive.com/zfs-discuss at opensolaris.org/msg37288.html and here: http://opensolaris.org/jive/thread.jspa?messageID=474765 <http://opensolaris.org/jive/thread.jspa?messageID=474765&tstart=0> &tstart=0 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.

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
