So we have roughly 700 OpenSolaris snv_81 boxes out in the field. We're looking to upgrade them all to probable OpenSolaris 11.08 or the latest snv_10x build soon. Currently all boxes have a single 80gb HD (these are small appliance type devices, so we can't add a second hard drive). What we'd like to do is figure out a way via liveupgrade to upgrade to a newer SXCE release (or OpenSolaris 11.08) AND migrate the filesystems from UFS to ZFS at the same time.
The reason for wanting to go to ZFS is for the filesystem improvements and resiliency, as a lot of these boxes get power cycled regularly.. Here is the current partition table: /dev/dsk/c0d0s0 / 8gb /dev/dsk/c0d0s1 swap 1.5gb /dev/dsk/c0d0s3 /var 4gb /dev/dsk/c0d0s4 /backup 2gb /dev/dsk/c0d0s5 /luroot 8gb /dev/dsk/c0d0s6 /luvar 4gb /dev/dsk/c0d0s7 /export 45gb /backup, /luroot and /luvar are not in use. /export contains all the zones (each box has 3 non-global zones on it) I was thinking about removing the /backup, /luroot, and /luvar partitions and using that to create a ZFS rpool on it, then installing the new OS onto that, but /export needs to stay with the zones on it. An alternative option is to just re-install the boxes from scratch, and devise a way to auto-configure them when they boot back up (they are all remotely located and there's no console access to any of them, so that's a bit tricky) Anyway, just wanted to toss the idea out, see if anyone has done a UFS -> ZFS in place upgrade while doing a live upgrade (or post live upgrade is also an option of course, so long as it can be scripted) Thanks! -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
