Simon> Please do share your unhappy experience with 3ware. We've had one troublesome system, running supported IBM disks (120 GB IC35L120AVVA07 disks) where we have repeated drive timeout errors, and recently the mirror sets (we're running 4 disks in a RAID-10) get out of sync. I had it once where the system was still stable (kind of at least) and an MD5 checksum of a large file would come up different, but always one of two values. I did the "verify array" operation at the BIOS, and it found "an unknown error". (If its unknow, how can it be an error?) This causes the volume to be initialized, and then my MD5 checksum is always the same. We just had one of our MySQL servers die with a corrupted page in the database, ran the verify array on that system, and again we got the unknown error. (This system also has supported disks, the IBM 80 GB IC35L080AVVA07.) I'm really getting worried now with the mirror sets getting out of sync, this is not a good thing at all. The rumor mill has 3ware supporting FreeBSD directly with their 7.7 release of drivers, so I'll probably try that when it happens. simon> 3ware can email you if something goes wrong, no need to watch simon> syslog. Right, I guess I just like the syslog approach, it works even if 3dmd isn't working, or the system is so borked it can't send email, in which case it probably can't send a syslog message either. :(
