Hi,
We are using multiple opensolaris 06/09 and solaris 10 servers.
Currently we are 'dumping' (incremental)backups to a backup
server. I wonder if anybody knows what happens when I send/recv a
zfs volume from version 15 to a (backup) system with version 14.
I've the feeling it's not very wise to do, but is it doable and
what kind of caveats can be expected. Probably we will upgrade the
backup system to version 15 sometime soon.
You are referring to the zpool version, not the zfs version. The
latest
zfs version is 4. To see the available zfs versions use, "zfs
upgrade -v"
Cindy, this doesn't come up very often, probably because there have
only been 4 zfs versions, but perhaps it deserves mention in the
"Receiving a ZFS Snapshot" section of the ZFS Admin Guide.
You are right, I'm mixing up zpool and zfs versions. But, in this
case I'm backing up/transfering zfs volumes, and if I request
version information about a zfs volume, the value for version is
empty. Still I have problems with send/recv to an older zpool
version, but I don't know of this can be the cause or maybe
something else is wrong..
I tested this before I posted yesterday and it worked fine.
What error messages are you seeing?
