Zevo -> FreeBSD

Post by monkeyfoahead » Mon Jun 10, 2013 4:16 pm

Anyone here successfully import a Zevo pool into FreeBSD? I am afraid to try.

Common anybody? Can I potentially damage my zpool on an import?

Have you tried with a throw away thumb drive or something? I've been thinking about trying the same thing on ZFSonLinux.

You can import pool from ZFSonLinux if it was created without feature flags support (-o version=28).
And you can import Zevo pool with ZFSonLinux, just don't upgrade it after.
I believe same will happen with FreeBSD.

This is excellent news, if it can be confirmed for true. What do you mean do not upgrade it? Are the versions not the same between Zevo and FreeBSD?

I inadvertently confirmed that ZoL v28 imports into Zevo without issue, so I dont see any issues going the other way assuming both sides support the underlying zpool version you happen to have (e.g. 28 -> 28, or 5000 -> 5000). A little caution would go a long way, though. If feasible, zfs-send your data to a secure backup location before trying ;)

Sweet, well unfortunately I have a zpool of over 10TB so I don't have anywhere to send it haha

ZEVO and FreeBSD 9 both use pool version 28. ZFS on Linux uses pool version 5000.

Right, right I looked this up. I was just afraid their would be implementation differences that my bite me in the rear.
