Boot Issues


So I've had this server running for like 4-5 years without a hitch on Fedora 7. I have 4 drives with the OS partition in raid 10, and the /boot partition in raid 1. For some reason I'm having issues with grub. I have KVM access to the machine.

The server boots straight into Grub. Running "find /grub/stage1" or "find /boot/grub/stage1" does not find anything.

I have it booted currently in CentOS LiveCD and mounted the primary OS partition and it mounted fine and mdadm doesn't report any problems with the array. But when I tried to mount the /boot partition (raid 1 across all 4 drives), it gave me this error...

Code:
# mount /dev/md0 /mount
hfs unable to find hfs+ superblock
mount: you must specify filesystem type
Is this normal for the boot partition or what do you guys think is wrong? I'm completely new to fixing Grub issues but this is where I got so far. The OS data seems to be intact, I just need to find a way to boot into it >_>.

Thanks in advance for any and all help.

This is not a grub issue. It seems that the filesystem on your boot partition is corrupted (is that really a HFS+ partition?). The correct way to fix that would be to reformat and and copy in the files from your backup.
It may be possible to repair that without recovering from backup. For that we need to know which file-system is on that partition. But I would think it is not worth the effort. Fedora 7 is unsupported since 2008. Time for a clean installation of a supported version.

I really need this server booted like it was before, after that I can upgrade but just the filesystem will not get me what I need from my databases. I don't know what the filesystem of the partition is, It was created with the default settings of of the Fedora 7 install at the time. /boot is supposed to be raid1 across all 4 drives. I've tried booting from all 4 drives separately but its all the same, I guess the array became corrupted. Any help is appreciated, its one of those times where just googling a problem isn't gonna help

I looked that up, the default filesystem in Fedora 7 was ext3, so I would try to boot a live-CD, like RIPLinuX or SystemRescueCD, start the RAID and run fsck on the /boot-partition.

Also, to get your databases it should be possible to boot from a live-CD and chroot into the /-partition. This way you should be able to backup your data (which normally should be done regularly, not in the case of an error).

OMG, thank you, can't believe something that simple fixed it. I just ran fsck on md0 and it fixed it, reboot and done. Thanks again.

Too late; deleted - glad you got it sorted.
