Hello all,
I upgrade from 9.0-BETA2 to 9.0-BETA3 (r225759) and when booting from a zpool I
get:
ZFS: i/o error - all block copies unavailable
can't open '/boot/menu.rc': no such file or directory.
I pxe boot mfsbsd 8.2-RELEASE + zfs v28
then:
mkdir /rpool
zpool import -R /rpool rpool
mount -t zfs rpool/boot /mnt
mv /mnt/boot/menu.rc /mnt/boot/Menu.rc
cp /mnt/boot/Menu.rc /mnt/boot/menu.rc
umount /mnt
shutdown -r now
and the next boot run smoothly...
Does your root fs have compression enabled?
The pool is a mirror:
[root@morzine ~]# zpool status rpool
pool: rpool
state: ONLINE
scan: scrub repaired 0 in 1h0m with 0 errors on Wed Aug 24 15:04:36 2011
config:

errors: No known data errors
and rpool/root is not compressed:
[root@morzine ~]# zfs get compression rpool/root
NAME PROPERTY VALUE SOURCE
rpool/root compression off inherited from rpool
pool is v28 and filesystems are v5
PS.
I have to boot from pxe because after the i/o error, the kernel was booted but
encounter a double fault. I try 5 times with the same result.
I think that on my configuration only the kernel without ACPI encouter this
trap.
I think that you should try to gather and report more information about the
panic
(separately).
I'll try this saterday
