Folks, I'm trying to figure out whether we should give ZFS / mpxio a shot on one of our research servers, or simply skip it (as we have previously).
In Nov 2009 Cindy responded to a thread concerning ZFS device issues, cfgadm, and mpxio: http://mail.opensolaris.org/pipermail/zfs-discuss/2009-November/033496.html I've got an x2270 with the Sun EZ-SAS HBA and external SATA JBODs (not J4xxx). The external disks simply provide bulk storage; lousy performance is not a concern, reliability is. For obscure reasons, we're going to destroy / re-create those pools. We originally skipped mpxio due to the cfgadm issues, even though we'd have preferred to have the reliablity enhancements. Those issues seem to have re-appeared in various guises (e.g. bug 6948701, nominally fixed in s10u9). Due to the need to inter-operate (zfs send) with other s10u7 machines, I don't think moving to update 9 is an option (yet), nor is OSOL or SXCE. Bottom line: Do ZFS / mpxio / cfgadm issues still make mpxio an iffy proposition as a reliability enhancement? Is there a patch set that addresses ZFS / cfgadm / mpxio issues for s10u7? TIA.
