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

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
