Ok - this is really strange. I did a test. Wiped my second pool (4 disks like
the other pool), and used them to create a pool similar to the one I have
problems with.
Then i powered off, moved the disks and powered on. Same error message as
before. Moved the disks back to the original controller. Pool is ok. Moved the
disks to the new controller. At first it is exactly like my original problem,
but when i did a second zpool import, the pool is imported ok.
Zpool status reports the same as before. I run the same command as I did the
first time:
zpool status
zpool import
zpool export
format
cfgadm
zpool status
zpool import ---> now it imports the pool!
How can this be? The only difference (as far as I can tell) is that the
cache/log is on a 2.5" Samsung disk insted of a 2.5" OCZ SSD.
Details follow (it is long - sorry):
Also note below - I did a zpool destroy mpool before poweroff - when I powered
on and did a zpool status it show the pool as UNAVAIL. It should not be there
at all, if I understand correctly?
