The system was built up from a barebones Transport PX22, which uses a Tyan S2865G2NR motherboard. It has two drives: ad4: 286188MB at ata2-master SATA300 ad6: 286188MB at ata3-master SATA300 A while back I noticed in the daily periodic report that gmirror had dropped ad4. We rebooted and got things going again and it ran smoothly for a month or so, then dropped it again. At that point we did a warranty replacement of ad4 and things have been running smoothly for a couple of months. A few days ago gmirror kicked ad6 out of the raid, which the following lines in dmesg: ad6: FAILURE - device detached subdisk6: detached ad6: detached GEOM_MIRROR: Device gm0s1: provider ad6s1 disconnected. We're adding an external device into the mirror and are planning to do a warranty swap on this drive too. The system is running, but feels sluggish. It might be interesting to note that the disk activity light is continuously lit. The system if running the stock 6.1 RELEASE. FreeBSD foo.com 6.1-RELEASE FreeBSD 6.1-RELEASE #0: Sun May 7 04:15:57 UTC 2006 root@bloom.cse.buffalo.edu:/usr/obj/usr/src/sys/SMP amd64 I'm trying to figure out if we've just gotten two lousy disks, or if there might be a driver or motherboard issue. Does any of this ring any bells? I'm suggesting that we upgrade to the tip of the stable tree, but the owner's not convinced. I can't tell if there's been anything relevant in the stable release that might address this (aside from all the other great stuff that's in there). Thanks for any input, g.
