zpool version upgrade

June 23, 2006

After the latest upgrades to the laptops, again achieved my downloading the install image onto my external USB drive into it’s own ZFS file system so that I can destroy them with ease, zpool status said:

: sigma TS 11 $; zpool status   pool: home  state: ONLINE status: The pool is formatted using an older on-disk format.  The pool can         still be used, but some features are unavailable. action: Upgrade the pool using ‘zpool upgrade’.  Once this is done, the         pool will no longer be accessible on older software versions.  scrub: resilver completed with 0 errors on Fri Jun 23 17:22:11 2006 config:          NAME          STATE     READ WRITE CKSUM         home          ONLINE       0     0     0           mirror      ONLINE       0     0     0             c0d0s7    ONLINE       0     0     0             c6t0d0s1  ONLINE       0     0     0  errors: No known data errors : sigma TS 12 $;  zpool upgrade -v This system is currently running ZFS version 3.  The following versions are suppored:  VER  DESCRIPTION —  ——————————————————–  1   Initial ZFS version  2   Ditto blocks (replicated metadata)  3   Hot spares and double parity RAID-Z  For more information on a particular version, including supported releases, see: http://www.opensolaris.org/os/community/zfs/version/N  Where ‘N’ is the version number. : sigma TS 13 $; 

But http://www.opensolaris.org/os/community/zfs/version/3 gave a 404 error. A quick post to the opensolaris.org zfs-discsus group and a few hours later the page is there and in future there will be a http://www.opensolaris.org/os/community/zfs/version/N page as well. It also tells me that for my simple laptop setup there is no need to upgrade the zpool as I don’t use any of the features that are in the new version. So once again I will wait until I am certain I don’t need to down grade to build 41 before I do.


What I really like is that it was this easy to get something fixed.
