[ Sending this here, as I've publicly complained about this bug on the ZFS list previously, and there have been prior threads related to the fix hitting OpenSolaris ]
For those of you who have been suffering marvell device resets and hung I/Os on Sol 10 U4 with NCQ enabled, you should talk to your Sun support folks about IDR137601-02. We have one server that could consistently reproduce the problem, and it's been running since Friday with NCQ enabled and no hangs after applying the IDR. We had tested previous IDRs that did _not_ fix the problem, but so far, so good... While we had a rough start with support on this issue, kudos to the engineers for finally tracking down this heisenbug (fingers crossed...), and here's hoping it makes it into a public patch soon. -- Carson _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
