hi,
I'm running FreeBSD-CURRENT r224522M installed on ZFS Root and GPT
partitions and this setup is running fine. Today I've updated to r225312 and
after rebooting I've got following error message from boot loader:
ZFS: i/o error - all block copies unavailable
Then I did "zfs rollback" using rescue disk to previous revision and I was able to
boot.
Steps I did to update system:
zfs snapshot
make buildworld
make buildkernel
make installkernel
reboot
can't boot
zfs rollback using rescue disk
boot to previous revision (r224522M).
Are there any more steps required for this procedure to work?
My previous updates from source on the same setup where successfull, this is
the first time I've encountered this error message when upgrading from source.
My setup:
gpart show

34 128 1 freebsd-boot (64k)
162 1886 5 bios-boot (943k)

50333696 199735951 4 freebsd-zfs (95G)
Partitions 3 and 4 are separate zfs pools (3 is geli encrypted and 4 is for
operating system).
