Personally, I haven't had major issues with ReiserFS. It had some problems when it first came out, but has become quite the stable filesystem since then. In fact, I once had to use an early version of it when an RH 7.x system kept hitting a race condition with ext3 (I couldn't upgrade to the patched version of the kernel, the system was running software that had a license key tied to the software versions - evil). The main thing to look out for is keeping uncompressed copies of reiserfs-formatted files (disk images) on a reiserfs drive. That totally breaks things when you run an fsck. Honestly though, unless you need the journaling capabilities, look at the non-journaled systems like ext2 as well. In most situations, your queue won't need to be journaled, and neither will your logs. !DSPAM:476beb90310541644812091!
