[-- Attachment #1 --] First, let me thank you all for offering help. I really appreciate it. I'm going to try to respond to all your comments and questions in-line here: > Maybe post the setup of your disks. So people can take a look if your > commands are right or wrong. The output of 'gpart show' and 'gpart list' > are a good starting point. I've attached the output of both commands to this e-mail. Incidentally, this zpool was built using mfsBSD (http://mfsbsd.vx.sk/) originally as a FreeBSD 8.2 system, if that matters. > As it was already indicated, there is no support for zpool version 5000 > (feature flags) in base/releng/9.1. There is however in base/stable/9 and > in base/stable/8 what you obviously has before. I'm quite certain I've never tracked anything other than the following two Subversion URLs for my /usr/src: http://svn.freebsd.org/base/releng/8.2 http://svn.freebsd.org/base/releng/8.4 http://svn.freebsd.org/base/releng/9.1 As I understand it, those are supposed to be only "release" versions; they aren't "stable" versions. Or am I using the incorrect URLs? > One thing that comes to mind is some older setups may only have 32K > freebsd-boot partitions, and gptzfsboot is 41K at present. I'd expect an > error on trying to install the bootcode, but have not tested it. This has never been anything other than a 64-bit machine. > can you run 'zpool history | grep upgrade' and see if it recalls any > upgrade commands? Actually, I can't right now. All zfs-related commands fail with: internal error: failed to initialized ZFS library I suspect that's because I don't have a proper /dev and because my boot environment is now on an inaccessible mount point, as my boot root partition has been over-mounted with my zfs root partition: /dev/iso9660/FREEBSD_INSTALL on / (cd9660, local, read-only) devfs on /dev (devfs, local, multilabel) tank/root on / (zfs, local, noatime, nfsv4acls) tank/root/jails on /jails (zfs, local, noatime, nfsv4acls) tank/root/jails/db-01 on /jails/db-01 (zfs, local, noatime, nfsv4acls) tank/root/jails/www-01 on /jails/www-01 (zfs, local, noatime, nfsv4acls) devfs on /jails/db-01/dev (devfs, local, multilabel) devfs on /jails/www-01/dev (devfs, local, multilabel) So, I was thinking about possible recovery modes now, and I wonder: it seems that the zpool version has been upgraded to something that's not supported by releng/9.1, but the ZFS file systems themselves are still at version 5, as far as I can tell. So, wouldn't it be possible to "zfs send" my file systems to another box that is running releng/9.1 so that the snapshots are preserved, rebuild this box as a fresh releng/9.1 install and then "zfs send" the file systems back again? Or does upgrading the zpool also affect the zfs file systems, even if the zfs file system version hasn't changed? -- Tim Gustafson tjg@ucsc.edu 831-459-5354 Baskin Engineering, Room 313A [-- Attachment #2 --] Geom name: da0 modified: false state: OK fwheads: 255 fwsectors: 63 last: 1953525134 first: 34 entries: 128 scheme: GPT Providers: 1.
