Probably because the fault occurred in the ZFS module the OS can't do a
core dump into the ZFS dump volume. You can get around this by using a
physical partition or disk for the dump device. The simplest solution is
to just stick an extra HDD in the box, run
dumpadm -d /dev/dsk/HDD_device_node and then try to import the pool.
After this the HDD should contain the dump file which you can salvage
using savecore. For me, I do development of ZFS itself, so I get quite a
few ZFS-related crashes, so I've set up my L2ARC device with two
partitions - one used in the pool for L2ARC, the other dedicated to dump
(obviously this only makes sense for development and not for production).
