OK, the issue seems to be resolved now-- I'm seeing write speeds in excess of 160MB/s. What I did to fix things: 1) Redistributed drives across controllers to match my actual configuration-- thanks to Nigel for pointing that one out 2) Set my motherboard controller to AHCI mode-- thanks to Richard and Thomas for suggesting that. Once I made that change I no longer saw the "raidz contains devices of different sizes" error, so it looks like Bob was right about the source of that error 3) Upgraded to OpenSolaris 2010.03 preview b132 which appears to correct a problem in 2009.06 where iSCSI (and apparently FC) forced all writes to be synchronous -- thanks to Richard for that pointer. Five hours from tearing my hair out to toasting a success-- this list is a great resource! -- Dave Pooser, ACSA Manager of Information Services Alford Media http://www.alfordmedia.com _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
