If you can successfully mount the partition in read only mode (I was able to do so at my failure), you can certainly mount the partition on another linux system with reiserfs support and try to copy off the files you need. Knoppix (CD based system) is an excellent recovery tool. I wish you the best of luck. I'm sure you must have read the replies to my suggestion. Filesystem discussions most often result in a flame war. I know lots of people use reiserfs successfully, but my two attempts over a period of 2-3 years resulted in disaster, so I have signed off permanently. The fact that the filesystem can (under somewhat diverse circumstances) fail to locate the superblock makes me question the total design, since the purpose of a journaled filesystem is to recover properly when the system is out of sync. Once you get out of the woods, you can decide what to do. I personally have never never had a single problem with ext3 (oops, see below); others swear by XFS (running servers for many years). My only objection to XFS (until recently) was that you had to obtain separate kernel patches, and these had to be reevaluated each time the kernel changed. XFS has now been ported into the 2.6 kernel, but the level of XFS activity recently in kernel releases makes me suspect that it is not quite ready for prime time. Now that I remember, there was one oddity on my system with ext3 at least 1 1/2 years ago. I had a single directory with a small number of files under my home directory that would not permit writes. I had to copy off the files (all were intact) and rebuild the directory. This pales in comparison to what you are experiencing. -- Collins - Denver Area - Gentoo stable kernel 2.6.2-rc1 -- [EMAIL PROTECTED] mailing list
