Summary: JFS corrupts file systems on 64bit architectures
Kernel Version: 2.6.0test2
Status: NEW
Severity: high
Owner: [email protected]

On AMD64 JFS seems to corrupt file systems quickly. I created a JFS file system, rsync'ed an BKCVS kernel checkout from another box then did two cvs updates. Result was that several directory inodes in the kernel tree were unreadable on the next access (always returned EPERM even for a stat). I did a fsck then, which found some bad inodes and resulted in a endless lost+found (ls ran out of memory trying to list it)

2.4 JFS still worked. I also got feedback from one user that they are seeing similar problems on sparc64.
