Ok, I changed the cable and also tried swapping the port on the motherboard. The drive continued to have huge asvc_t and also started to have huge wsvc_t. I unplugged it and the 'pool' is now operating as per expected performance wise.
See the 'storage' forum for any further updates as I am now convinced this has nothing to do with ZFS or my attempt to disable the ZIL. 8-) -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
