I went to check it and it was saying there is a problem with the filesystem, and stated 'you should run fsck manually'. I ran fsck on the relevant partition and fix all the inode problems suggested. After restarting I am now shown the following messages: JBD: no valid journal superblock found EXT3-fs: error loading journal mount: error 22 mounting ext3 Switching to new root ERROR opening /dev/console!!!!:2 Kernel panic - no syncing: Attempting to kill init Does anyone have any idea how I can resolve this? I am not particularly familiar with Linux so please be verbose when suggestions solutions. I don't want to reinstall Linux if I can avoid it as the server has about 5 years worth of valuable data on there.
