Each HU has separate ZIL and L2ARC devices. Hardware on both HU (inc. = SSD disks for ZIL/L2ARC) is identical. This is basically a HA-setup. The I do an 'zpool export tank' on the first HU and do 'zpool import = tank' on the second one, only L2ARC device appears usable. Import fails, complaining about ZIL device not present.=20 According to the man page zpool(8) ZIL device can be imported and = exported. "=85 Log devices can be added, replaced, attached, detached, imported = and exported as part of the larger pool. =85". Do I miss something here? This feature not implemented yet? Any way to work around this, except that moving ZIL into JBOD? //maxim
