In my experience i ve also seen the same problems. a lot of sata disks (seagate barracuda ES.2 and other) all behind expanders (supermicro sc847 chassis) the issue were solved after we removed all sata disks behind our expander and replaced them with Enterprise SAS Disks. thereafter we only faced this problems when an connected sata-ssd died. so we also moved our sata-ssds away from this backplane and connected them directly to the 1068 based controller. the problem arrised, after we moved a identically server to a expander backplane (to get more drives connected). before this discs were running for months without any problems *direct* attached. regards daniel _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
