next in thread | raw e-mail | index | archive | help
I have been running 9.0 with zfs. two pools, both mirrors. One holds
the boot file systems (zroot) and the other just holds a huge amount
of data (zdata).
After upgrading to 9.2, I can still reboot, but the zdata pool is not
available. I am quite certain that there is no hardware issue (such as
a disk failure).
So how screwed am I? Is there a simple fix? Can I use freebsd-update
rollback to go back to 9.0 and hopefully get my data back? I've done
both the kernel, then reboot and freebsd-update the userland?
Here are some more details, if any kind and knowledgeable soul out
there can help:
Zroot is currently running on disks ada0 and ada2. For some reason,
zfs is trying to use ada2 as part of the ZDATA mirror:
>config:
>
> NAME STATE READ WRITE CKSUM
> zdata UNAVAIL 0 0 0
> mirror-0 UNAVAIL 0 0 0
> 1285589115166012386 UNAVAIL 0 0 0 was /dev/ada2
> 15986629349166314315 UNAVAIL 0 0 0 was /dev/ada3
Here is the gpart output:
=> 34 3907029101 ada0 GPT (1.8T)
34 128 1 freebsd-boot (64k)
162 25165824 2 freebsd-swap (12G)
25165986 3881863149 3 freebsd-zfs (1.8T)
=> 34 3907029101 ada2 GPT (1.8T)
34 128 1 freebsd-boot (64k)
162 25165824 2 freebsd-swap (12G)
25165986 3881863149 3 freebsd-zfs (1.8T)
These are the disks that are running zroot. There are three other
disks on the computer. One went bad, and is awaiting replacement. The
other two belong in zdata. I'm not sure how all of these are being
mapped to device names, but the bad one is reported as 'port0' on
boot.
I get these weird messages during boot:
