Well, now when i start the server all processes end up with [ FAILED ], and as error message i get a complaining that the filesystem is read only. So it cant delete or create any runfiles... I manage to login if i choose the failsafe option from the bootloader, and thus am able to do some limited things. I ran the e2fsck with -pf on all partitions but that didnt help. Does anyone have a clue what i could do except reinstalling the system.

From there: Code: mount -no remount,rw / __________________ the lost art of found sound

I ran,

Code:

e2fsck -pf /dev/hda1
e2fsck -pf /dev/hda6

(thats all of my partitions)

It says:

Code:

mount: /dev/hda1 already mounted or / busy
mount: according to mtab, /dev/ide/host0/bus0/target0/lun0/part1 is alredy mounted on /

But the error persists, upon boot (and shutdown, which i did forget to mention earlier) anything the loader does is responded by either; a) IOError [Errno 30] Read only filesystem b) [Errno 30] Read only filesystem c) Read only filesystem accompanied with the name of some file or pid that it tried to operate on.
