Can someone tell me how to work with reiserfstune and reiserfsck?
It depends on what you want to do. For checking the 1st partition:
Then it will display what it will do and you type Yes. That's the only thing I ever used. And it never found any corruptions. Reiserfs is pretty stable and robust, it doesn't need regular checks and repairs.
For most (all?) operations the partition must not be mounted in rw mode or even not mounted at all - see man pages for details
Yeah, so you have to use a boot cd to check/fix your normal boot partition. Why is this the case for reiser 3 but ext 3 allows the check at boot if tell it to in fstab?
