Hi,
Booting from ZFS hangs and system gets unresponsive. Details follow..
My system is an older installation where I have two 1TB disks with
several smaller partitions for testing and then a big one for FreeBSD.
The latter is comprised of 1GB UFS + swap + ZFS. UFS is used for
booting and then the whole system is on ZFS (as it used to be standard
before booting from ZFS was available). ZFS set up as mirror.
Now all ran happily until one day PC-BSD 8.2 was installed into one of
the small partitions. No idea why but since then FreeBSD wouldn't boot.
It started displaying the prompt below but either keyboard is ignored
or the system hangs, as nothing can be done at that point.
GEOM_LABEL: Label for provider ... is ...
Trying to mount root from zfs:tank/ROOT
Manual root filesystem specification:
[...]
mountroot>
Now my question is what might have possibly gone wrong and how to fix it
? And by fixing I mean either making system run again (preferably) or
at least saving data (getting them of ZFS).
Thanks in advance!
M.
PS: I forgot to mention that this is FreeBSD 7.2 installation.
