I ran ReiserFSv3 on several servers in the past and was bitten by a number of corner case bugs introduced by (pre-Novell) SuSE. ReiserFSv4 is still considered experimental by its team.
I don't have any experience with Reiser
XFS has gained recent notoriety for losing the data of some prominent Linux figures. I remember that in the past few months, at least five people on various Planet aggregations said that XFS lost their entire partition and the recovery tools did not work.
I tried XFS for a while, but couldn't get a system stable enough to get through the install process, so I managed to side-step most of the data loss issues. I can vouch for XFS being unstable (circa Debian sarge) and the recovery tools not helping.
So, having heard very little about JFS, I'm interested in knowing if anyone here has been running it and has any experiences to share.
I've been running JFS (via Debian Sarge) since the release of Sarge on various platforms (x86 and 64-bit on AMD64). I've only had a couple of issues:
1) Although grub claims to have JFS support, it didn't seem to work in the real world, so my /boot partition is ext3 (everything else, including root, is on JFS). This may already be fixed by more recent versions of grub.
2) One system foo-bar'd the JFS filesystem when it completely filled the allocated space (before I noticed and could allocate more via LVM). I lost a few files that were open for writing at the time (mostly log files), and I had to run the fsck utilities a couple of times (until I manually forced complete checks of the entire FS, despite the fact that the journal indicated the FS was OK), but nothing major. Pretty much everything was back to normal once I added space and properly fsck'd. I have completely filled other JFS partitions (ie: /home/DVDs) with no issues whatsoever (ie: delete a few files and go back to work).
NOTE: I'm running most systems with JFS on LVM on SW-RAID (1 or 5). A couple of systems have HW-RAID (3-Ware 95xx SATA controllers), and everything seems to get along nicely.
