zfs discuss - Aug 2008 - Live resize/grow of iscsi shared ZVOL

I have created a zvol. My client computer (windows) has the volume connected
fine.
But when I resize the zvol using:
zfs set volsize=20G pool/volumes/v1
.. it disconnects the client. Is this by design?

Did anyone reply to this question?

We have the same issue and our Windows admins do see why the iSCSI target should
be disconnected when the underlying storage is extended

Is there any iscsi target that can be extended without disconnecting
the target? AFAIK Linux''s iscsi target does the same thing, the size
change is only recognized when the iscsi daemon was restarted.

My EqualLogic arrays do not disconnect when resizing volumes.

When I need to resize, on the Windows side I open the iSCSI control panel, and
get ready to click the ''logon'' button. I then resize the
volume on the OpenSolaris box, and immediately after that is complete, on the
Windows side, re-login to the target. Since the Windows initiator can tolerate
brief disconnects, IO is not stopped or adversely affected, just paused for
those few seconds. It works fine. Multi-path is a little more complicated as you
would have to re-logon to all of your paths, but if you have at least one path
active, you should be fine.

I am certainly a little late to this post, but I recently began using ZFS and
had to figure this all out.

There are ways to do this without disturbing the volume or removing it and
re-connecting it on the Windows side.  I had a bit of research involved, and I
put up a blog about it.  Plan to share most of my opensolaris and future zfs
tidbits there.

Hope this helps people!
