Hi All:
I meet a great issue on import zpool from one day the hardware crashed (replaced the raid card finally), for my scenario, I do not use multiple HDs to form raidz, I use a physical RAID card to form a hardware RAID-5 instead, so I use a single partition for zpool create pool_name /dev/da0p4, and now the symptoms are;
will cause kernel panic and reboot automatically too.
but however, I can perform a scan on this pool
anyways I could remount/import (even read only) the pool to get the data back?

Code:
zpool import pool_name
zpool import -F pool_name
will cause kernel panic and reboot automatically too.
Code:
# zdb
cannot open '/boot/zfs/zpool.cache': No such file or directory
but however, I can perform a scan on this pool
Code:
zdb -AAA -F -X -cc -L -e -mm pool_name
