Hi,
Is their any gotcha when using ResiserFs as a file system?
You have to be careful with which OSes you use it with, for example, you can't really get a "base install" with ReiserFS, nor a default RescueCD with it...you'd want to choose a partition to dedicate for ReiserFS, and make sure you had among your DR tools a disk that has ReiserFS kernel module and tools.
ReiserFS is more CPU intensive, so using it on a lower-powered CPU will have more load. ReiserFS also is not a "robust" as extX file systems. So if you kick your power cord out when someone sends you a killer joke, ReiserFS is more likely to lose data. Hearsay has it that it's harder to recover data from.
My opinion on when to use ReiserFS is under these conditions: - stable server, backups and raid - used on an appropriate volume, not all volumes - you want conserve disk space because you're handling a large volume of files that are typically smaller than your filesystem block size (for example, you'd lose a lot space in /var/spool/imap if your ext3 fs blocksize was 8K. - you have DR utilities to cope
