Precisely, and then I removed the controllers Raid6 config and exported the now unused 7.2k Sata discs into Solaris as single R0 vol's for the server to perform Raidz2 with and that allowed the before unusable workload which stalled that IO subsystem out to the point of clients failing writes to my doubling the client count on this system. jlc _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
