Um, well, that shouldn't cause all of your volumes to go offline (I
assume you mean AFS volumes). Logs should say why they are doing that.

The AFS-specific fsck is only needed when you run the 'inode' fileserver
backend. With Linux on 1.4.11, you can only be running the 'namei'
fileserver backend, which uses the filesystem like any other program.
You can use the regular ext3 fsck without worries.

And there are known security problems with 1.4.11 that have been fixed
in 1.4.14. Just by the way.
