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).
