Disk in scsi raid1 fails-how torecover?
My worst fears have been realized!
I've got a file server running RH9 on a Tyan/AMD MB with on-board scsi controller. The OS is on a 30Gb IDE drive and data is stored on two 37Gb scsi hd's in a raid1 array. Today we had some violent weather pass thru and power was going on/off continually for about an hour. Even though the server was on a UPS it finally just crashed, went off-line and just sat there with the hd light on, nothing on the monitor, keyboard did not responed. Pulled the plug, then restarted. Boot up proceeded OK except I saw the message during boot "md0 startup......sda1 failed, disabling device. No extra drive found to reconstruct, continuing with sdb1". Boot completed and all services came back and when I ls /data it's all there. I did a "cat /proc/mdstat" and it only showed sdb1.
I have two new 37Gb scsi hd's still in boxes. What's the best way to put this thing back together? I see lots of info on setting up raid, but how to recover when one drive fails and the other is still running?
Thanks for your attention!
