Re: Upgrading FreeBSd when using a zfs-only installation?
--As of March 16, 2011 10:17:12 PM +, Matthew Seaman is alleged to have said: I suggest you try out your update in a VM then, because I doubt anyone will produce an answer definitive enough for you. --As for the rest, it is mine. In case anyone still cares, and if a VM running in Parallels on an OS X box is a good enough test for people... Matthew's answer tested out as being correct. The VM booted correctly after the binary update, but failed after upgrading the version of the zpool. Notably, `zpool upgrade -a` mentioned this in it's output, and gave the command to fix the problem. (Which would update the bootloader.) Daniel T. Staal --- This email copyright the author.

I thought Matthew Seamans' answer sounded pretty definitive: A system update via freebsd-update or otherwise won't touch whatever bootblocks you have installed. So if you have already installed gptzfsboot and your system already boots ZFS v12 then it will continue to boot ZFS v12 without your touching anything to do with boot blocks. However, with the 8.1 - 8.2 upgrade, you get (inter-alia) ZFS v13 support (I think it's v13 -- all my personal kit is running the stable/8 v28 patchset...) plus equivalent zpool version bump. The 8.1 bootblocks don't understand ZFS v13. If you wish to update the on-disk formats of your ZFS stuff: 'zpool upgrade -a' or 'zfs upgrade -a' then you *will* need to reinstall the gptzfsboot boot-blocks. You don't have to update the ZFS formats, but you'll miss out on various performance and bug-fixes if you don't. Given that the gptzfsboot boot blocks are backwards compatible to older ZFS versions, highly recommended to update the boot blocks even if you aren't intending to upgrade the ZFS bits just yet. Just as an anti-foot-shooting measure. By that: You don't _have_ to do anything. But it is probably a good idea. Daniel T. Staal --- This email copyright the author.

The question I have is, does anyone know *definitively* if the same thing that broke 8.0 to 8.1 will also likely occur in 8.1 to 8.2, or does the bootloader in 8.2 now contain what /boot/gptzfsboot contained in 8.1?

Well those are his modified upgrade instructions, they seem relatively sound but the extra steps aren't required. The gpart stuff is to update the boot loader which is only necessary if you upgrade the file system or pool eg zfs/zpool upgrade. You should probably run this just to prevent potential severe pain later. And as it's said, the nextboot is there because he's running a custom kernel and wants to boot into GENERIC next time then later rebuilds his custom kernel. The short story is if you are running GENERIC anyway, a standard binary upgrade would work fine, but if you have taken a divergent path you'll have to account for those differences in your upgrade process. -- Adam Vande More ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
