I had a sparc64 (Netra X1) running a stable/9 from late March 2013. =
Actually, the kernel may've been a bit newer than that as I was working =
with folks to diagnose and repair some Netra-X1 specific issues. But, =
ZFS worked fine. I have two pools, zroot as a RAID1 (using equally =
sized partitions at the front of two large disks), and a zdata that is a =
large pool of the remaining space of both disks concatenated together.
After installing a kernel from a build of [yesterday's] stable/9 =
today, I now get a failure when trying to boot, which can be seen at the =
end of this clip from the end of the boot messages below.
Is anyone aware of a change in recent months that might've caused =
this, or have any idea what I may've done wrong? In google'ing I've =
seen a few posts talking about ways to import the zfs pool to adjust the =
cache file, but I'm not sure if that is or isn't my problem. I don't =
think I did anything specific with configuring cache files for either =
pool.
Thoughts are welcome. I don't have physical access to the machine for =
quite a few more hours, but when I do should be able to net-boot into =
the earlier freebsd stable/9 that I originally installed onto this host, =
and can try a few more things.
