Those SIL chips are really broken when used with certain Seagate drivers. But I have data corrupted by them with WD drive also. Linux can workaround this bug by reducing transfer sizes (and thus dramatically impacting speed). Solaris probably don't have workaround. With this quirk enabled (on Linux), I get at most 20 MB/s from drives, but ZFS do not report any corruption. Before I had corruptions hourly. More info about SIL issue: http://home-tj.org/wiki/index.php/Sil_m15w I have Si 3112, but despite SIL claims other chips seem to be affected also. -- Tomasz Torcz [EMAIL PROTECTED] _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
