Hi, all,
I think I'm missing a concept with import and export. I'm working on
installing a Nexenta b134 system under Xen, and I have to run the installer
under hvm mode, then I'm trying to get it back up under pv mode. In that
process the controller names change, and that's where I'm getting tripped up.
I do a successful install, then I boot OK, but can't export the root pool (OK,
fine). So, I boot from the installer cd in rescue mode, do an 'import -f' and
then 'export'. That all goes well.
When I reconfigure the VM and boot back up in pv mode, if I bring it up under
the CD image and do 'zpool import', I get:
==========
r...@nexenta_safemode:~# zpool import
pool: syspool
id: 5607125904664422185
state: UNAVAIL
status: One or more devices are missing from the system.
action: The pool cannot be imported. Attach the missing
devices and try again.
see: http://www.sun.com/msg/ZFS-8000-6X
config:
syspool UNAVAIL missing device
mirror-0 ONLINE
c0t0d0s0 ONLINE
c0t1d0s0 ONLINE
Additional devices are known to be part of this pool, though their
exact configuration cannot be determined.
===========
I thought the purpose of the export was to remove concerns about which devices
are in the pool so it could be reassembled on the other side. But, like I
said, I think I'm missing something because 'export' doesn't seem to clear this
up. Or maybe it does, but I'm not understanding the other thing that's
supposed to be cleared up. This worked back on a 20081207 build, so perhaps
something has changed?
I'm adding format's view of the disks and a zdb list below.
Thanks,
-Bill
