One thing that I recommend to all ZFS users is to make use of boot environments. They are very easy, very convenient and may save a lot of trouble. Use either any of the tool available in ports (e.g. sysutils/beadm) or just "do boot environments" in an ad hoc fashion: snapshot and clone your current / known good boot+root filesystem and you have a safe environment to fall back to. > I thought r236884 requiring a zpool upgrade was the culprit, but > it wasn't.

It's also available in zdb(8). zdb -l should be used with disks/partitions/etc, not with pool names. > I'm running into the same behavior before and after I upgraded sac/sac2. > My git branch is a lightly modified version of FreeBSD, but > doesn't contain any ZFS specific changes (I can point you to it if you > like to look at it). > Would appreciate some pointers on what to do next. Try to get a working environment (using livecd, another disk, backups, etc), try to follow the original instructions. -- Andriy Gapon _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
