Hi Richard, Yes, I did miss that one, but could you remind me what exactly are the sd and ssd drivers? I can find lots of details about configuring them, but no basic documentation telling me what they are.
I'm also a little confused as to whether it would have helped our case. The logs above seemed to indicate that Solaris ignored huge numbers of timeouts before faulting the device. I'm guessing that's down to FMA, and as far as I know, that's not tunable is it? And yes, I spotted the iSCSI time outs, thank you. A couple of people have pointed that out to me now and I'm looking forward to testing it out. But coming back to the timeouts, (and I know I'm going over old ground - feel free to ignore me *grin*), you're saying that a tenth of a second is way too short, and it needs to be at least 10s. Why is that? An Intel SSD device can return results in around 0.2ms. Waiting 10s is enough to delay 50,000 transactions, and around 2.5GB of data. If I've got a mirrored pair of those SSD's, I really don't want ZFS to even wait a tenth of a second before trying the second one. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
