Well, I may have misspoke. I just spent a good portion of yesterday upgrading to the latest firmware myself (downloaded from SuperMicro's FTP, version 1.26.00 also; after I figured out I had to pass the -o option to mptutil to force the flash since it was complaining about a mismatched card or some such) and I thought that the machine had locked up again later in the day yesterday because I couldn't ssh into the machine. To my surprise though, I was able to log into the machine just fine this morning directly on the console from the command line. It seems the snv_125 bug with /dev/ptmx bit me (the "error: /dev/ptmx: Permission denied" problem that required me tracking down the release notes for snv_125 to figure out the problem) and the server was happy otherwise. More importantly, the zpool activity had all finished and I have three clean spares again! Normally this amount of I/O would have totally killed the machine! So somewhere between upgrading the firmware to the latest version and upgrading to snv_131, it looks like the problem may have actually been addressed. I'm guardedly optimistic at this point, given the previous problems I've had so far with this on-board controller. Interesting to hear someone else with the same chip but on an expansion card has no problems (but was with the on-board chip). -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
