Hi All, We are using Promise RAID controllers built on motherboards. These provide simple RAID-1 mirroring for us. We had a disk fail a couple of weeks ago, and it took the whole system down. The console was still up, but the machine was unresponsive over the network. Looking at the console, it reported a hard-disk write error on the second IDE drive in the RAID configuration, on the swap partition. This was not a good thing, as we had to drive to our data center and find out what was wrong. My assumption would be that the RAID controller would respond and automatically detach a bad disk. Is anybody else working with the Promise controllers (device ar) in a production environment and found a way around this? The only thing I can think of, is to run a cronjob to watch the log file every couple of minutes looking for, and parsing, any disk failure messages and then detach the drive and fire off an e-mail. This is obviously a kludge, and it would be a lot better to pickup a signal from the ar device driver or something if there is a failure. Any ideas would be helpful. - Mike Michael F.
