Here is a small comparison of the kernel modules (size):
I used to have JFS as my default filesystem for Linux until a few years ago when I switched to Ext4. It was indeed a fast file-system, especially for large number of files, however I think it suffers from lack of attention from developers. Moreover it happened to me once during an online-resize that the kernel issued an error and remounted my partition read-only. Luckly nothing was lost, however it wasn't a pleasent experience. As some others on this list have mentioned, JFS and power failure don't mix well and usually it loses your file (i.e. truncates it); however I bet the issue here is not the actual file-system but the applications that don't `fsync` a file before `close` and just assume that `write` + `close` implies persistance. (As this happened to me also on Ext4.) Ciprian.
