ZFS send to FreeBSD

[filipp]

We're in the process of migrating our file server from FreeNAS 9.2.1.6 to FreeBSD 10-RELEASE. I had hoped I could just move the zpool, but unfortunately that's not possible. I could create a brand new pool and restore the data from a current replica of FreeNAS, but the question is - can I use ZFS send between datasets with different ZFS features? I'm thinking this is another gig for rsync, but ZFS send would be faster.

Probably be better to try FreeBSD 9.3 or 10.1. I think both have all the ZFS features that FreeNAS 9.2.1.6 has. I think FreeBSD 9.3 even has one extra. It is possible to move pools if you are careful to create the pool with all features off, and then only turn on those which are supported across your desired systems.

LOL. I don't think you read filipp's post. He already said it's not compatible with 10.1. So telling him to try it is not exactly helpful. :P

I'm 99% sure you can ZFS send with some flags not carried over. Naturally you'll lose those functions but it won't matter anyway since you obviously don't need them.

Thanks. Does 9.3 really have com.delphix:hole_birth? Would you run 10.1 in a mission-critical production environment?

 

[filipp]

Oh, looks like it does indeed: http://www.freebsd.org/cgi/man.cgi?query=zpool-features&sektion=7 I think I might actually give 9.3 a try. Thanks for the hint!

Personally I wouldn't run 10.0 on production because the x.0 releases usually have quirks. 10.1 isn't released yet so I wouldn't run it as they are still working out the bugs. 9.3 is what I'd recommend as it just hit RELEASE recently.

 

[filipp]

Roger. I'll give 9.3 a shot and report back. Thanks for your input, rs225 and cyberjock.

I'm running FreeBSD 9.3, but haven't tried 10 yet. 10.1 will be the first one I try, since 9.x is ending at 9.3. Since 10.0 had a lot of changes, I do like to avoid the .0, and I will have to test for driver and compatibility issues before the change.

9.3-RELEASE worked great. I've now actually migrated our primary file server from FreeNAS to 9.3. Thanks again!
