[zfs-discuss] ZFS/zpool Versions in Solaris 10
All, Is there anywhere which suggests what versions of zfs and zpool will make it into Solaris 10 update 7 05/09 next month? I''m currently running Update 6 on an x4500 but would really like to have the new zpool scrub code released in version 11.

I did get into trouble recently that SX-CE 112 created a file system on an old pool with a version newer than Solaris 10 likes :( maybe you can get the scrub features without a pool version change--I don''t know what the new features are so I can''t easily tell.

Don''t know where all of the corner cases are, but this appears to be a workaround. Just keep a table of the pool and filesystem versions for each release handy. # zpool create -o version=10 newpool c0d0s4 I did this on nv112 and ..... drum roll please ...... it can be imported on Solaris 10. Same thing for ZFS. # zfs create -o version=1 rpool/legacy-file-system Also created on nv112 and also .... wait for it ....... mountable and totally usable on Solaris 10 10/08. It''s a beautiful thing. Bob

I figured that much, just got surprise (and only recently), and when I switched back to S10 8/07 to diagnose a customer problem, I got error messages! Fortunately it was still able to boot, and mount! # zfs get version mypool/zones-snv112-090414/master NAME PROPERTY VALUE SOURCE mypool/zones-snv112-090414/master version 2 - # zfs get version mypool NAME PROPERTY VALUE SOURCE mypool version 1 - Note that the file systems are being created by zoneadm. However, since I created the mypool/zones-snv112-090414 filesystem by hand (on 112), I will have to verify that a clone of it will keep the version as the origin. Steffen> Bob
