Hi list
Today my dear server had some problems.... I�ve arrived at work, and the server had hanged, after a reboot (and a loooong wait while system was checking MD0) I was able to "destroy" the RAID (hda3 + hdc3) change fstab to mount / just with hda3....
after the system was running, i�ve tried fsck.ext3 an hdc3, and.... server crashed after another reboot, system was unable to mount hdd too....
Well, everything points to hardware failure... but... 2 discs at once???? I�m afraid of IDE controller error, and after a google harvest, have found some people with the same error messages, but apparently with config problems... Or, I hope... cable.
Run a test with smartmon tools: smartctl -t short /dev/hda (there are other tests). For peace of mind you might prefer to take the disks out and do the test in another machine. I recommend booting off CD, especially if you do it in the same machine. I believe that Knoppox (4.0 is current last I looked) has the nexessary tools. At least one new drive is indicated regardless: it's safer recovering if you do it on a duplicate, and there's no telling what corruption you have now. I have had success copying a drive with DD, even when the target was larger, but I use ext2/ext3i* filesystems, and that may make a difference. * I saw your messages re EXT3, but I'd hate someone to assume that it will necessarily work with other fileystems: it might, but I don't have the experience.
Any clues???
