Hi All,
I would like to know whether the ZFS native API for SunOS
(http://www.opensolaris.org/os/community/zfs/source/) is publicly available
now? I see in some old mailing lists (2 years old) that they were not publicly
available. Is this still true?
Also I see there is a java API available at
I had a pool which was exported and due to some issues on my SAN i was never

Thanks.
I'll fiddle things so it tells me what the return value is and use the last
common snapshot rather than the last received snapshot.

Just reread your response. If the send/recv fails the snapshot should NOT turn

original on the sending machine is being destroyed by something (which I'm
guessing is the time-slider-cleanup cronjob below)
Here's the full c

Hi,
How do I discover the disk name to use for zfs commands such as:
c3d0s0? I tried using format command but it only gave me the first 4

names and others require 6 letters?
Thanks
