Reiser FS is a journaled b-tree high performance fs. Check out: http://www.namesys.com/content_table.html -Nick

Hi DJ, I don't know about ext3 but compared to ext2 the advantage is, that you got journaling; it means, after a crash, you will not sit there and look stupidly for half an hour or longer until the whole fs is checked. I use reiser since 6.4 (or so) and would honestly recommend it to all of you if you prefer your machine to be working over having troubles. Cheers ...

Reiserfs and other journalling fs show up to their best with large partitions. If something goes wrong with an ext2fs, such as a shutdown with one or more partitions not being properly unmounted, the entire partition or partitions have to be read for checking, and this can take a long time. In my (old) RedHat system, the boot process also does a filesystem check every 20 boots - very wise - no complaints. But it takes one hell of a long time. Reiser and other systems read back the journal, and goes straight to the point where there is trouble (if any). The result is that checks done after an illegal shutdown are carried out vastly quicker. I do not claim to be an expert on fs.

The main advantage is a filesystemcheck after for example a crash. A journaling filesystems needs only some seconds tho clean the system. - -- Ralf Prengel Dortmund -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (GNU/Linux) Comment: For info see http://www.gnupg.org iD8DBQE9UpvHgRRKXJrQjTsRAuDUAJ9U4XBU8cnxjKjWDxnIQDb5sHAqLQCfWZiX RRLM+zDEYT2KmGsqHLrecQM= =X2IY -----END PGP SIGNATURE-----
I 've heared enough about LVM. Question: can I change my root ext2 partition to LVM as it is running, you know in a production system?
Let me turn this one around. When I set up my laptop with SuSE 8.0, I used Reiser. However, I found I had some file system corruption. With ext[23] you can do a file system repair on the root file system (while in single user mode setting the file system to read-only). You cannot do this with Reiser. I recently discovered that my memory expansion module was bad, which I am surmising might be the cause of the corruption problem. I have just got another laptop, and I will be formatting it as ext3. The advantage of a journaling file system is that it will generally recover more qucikly. No long fscks. On 8 Aug 2002 at 10:50, Dennis Tuchler wrote:

I had a failing hard disk and on that hard disk was a ReiserFS partition. The partition became corrupt and I used the reiserfsck program to recover 90% of the data before the whole hard drive finally died.
