zfs discuss - Nov 2010 - How to zfs send current stage of fs from read-only pool?

Hello,
I''m trying to recover from zfs pool crash described here:
http://www.opensolaris.org/jive/thread.jspa?threadID=135675&tstart=0 --
I''ve successfully used Victor''s advice and now I do have my
pool imported in read-only mode. I see the data on filesystems and would like to
backup all of them using zfs send/zfs receive to another backup pool.
My problem is that `zfs send'' supports sending only of snapshot and I
cannot create any new snapshot on the read-only pool. Is there any workaround
for this? Something for example like virtual @now snapshot would be great to
have for those purposes IMHO...
Thanks for any idea!

Karel,

You can''t create snapshots in a read-only pool.

You will have to use something else besides zfs snapshots, such as
tar or cpio.

You could have used zfs send if a snapshot already existed but you
can''t write anything to the pool when it is in read-only mode.

Thanks,

Cindy
