Re: [zfs-discuss] zpool upgrade -v
Hi, I reinstalled our Solaris 10 box using the latest update available. However I could not upgrade the zpool bash-3.00# zpool upgrade -v This system is currently running ZFS version 4. The following versions are supported: VER DESCRIPTION --- 1 Initial ZFS version 2 Ditto blocks (replicated metadata) 3 Hot spares and double parity RAID-Z 4 zpool history 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. bash-3.00# zpool upgrade -a This system is currently running ZFS version 4. All pools are formatted using this version. The sun docs said to use zpool upgrade -a. Looks like I have missed something. --Walter On Fri, Jun 13, 2008 at 7:55 PM, Al Hopper [EMAIL PROTECTED] wrote: On Fri, Jun 13, 2008 at 4:48 PM, Dick Hoogendijk [EMAIL PROTECTED] wrote: I have a disk on ZFS created by snv_79b (sxde4) and one on ZFS created by snv_90 (sxce).

Hi Dick (from the solaris on x86 list), - First off, and you may already know this, you can upgrade - but it's a one-way ticket. You can't change your mind and go backwards, as in, down-grade to a previous release. And, what if you want to restore a snapshot to a box running an older release of ZFS... - Secondly, you're not *required* to upgrade. If there is even a 1 in a 1,000,000 chance that you might want to use the pool with a previous release of *olaris - *don't* do it! And this includes moving the pool over to a different *olaris release - which is a requirement that cannot always be foreseen. - 3rd, in many cases, there is no loss of features by not upgrading. Again - I say - in most cases - not in all cases. To examine the current version or to upgrade it, please read (latest version of) the ZFS admin guide doc # 817-2271. Look at zpool get version poolName and zpool upgrade Recommendation (based on personal experience) leave the ondisk format at the SXDE default version for now.
