I have just had a scary experiance wih my server running mdk 8.0. The system has now booted OK, but I would like to understand what could have gone wrong, and also what I can do to prepare for a disaster if this happens again, but this time does not recover.
Here we go: I booted the server as normal. When the init gets to the 'Partition check' it starts showing error messages saying that it cannot read the partition information. It then retries to read the partition and then continues with the other disks on the machine. The disk in question is 'hda' so when root is attempted to be mounted it fails with a VFS: Kernel panic. I cannot give any more info as I could not save the dmesg output, well I did, but I put it on the ramdisk...stupid ha. I booted using rescue mode of the mdk CDRom, I then attempted to e2fsck /dev/hda1. This completed....so I rebooted, this time the system gave the same error. I went back to he rescue mode and tried to mount the hda1, but this time it could not see the device. I tried to e2fsck -p /dev/hda, this completed with no messages and status 0. I don't know if this did anything, I know that e2fsck is designed for /dev/hda? but I am not sure if this is Ok for /dev/hda...your comments welcome. This time on reboot everything went OK. System booted, NFS, Samba all of it OK. I was very suprised. If any one has any thoughts as to possible reasons, steps to take to protect the partition info...(is this possible ?) Thanks in advance, David
