From Bugzilla Helper: User-Agent: Mozilla/4.77 [en] (X11; U; Linux 2.4.3-12smp i686) Description of problem: Impossible to unmount a ReiserFS filesystem on a 3ware RAID array. How reproducible: Always Steps to Reproduce: 1. Mount a ReiserFS filesystem sitting on a 3ware RAID array 2. Attempt to unmount the same filesystem 3. Actual Results: unmount process goes into an uninterruptible sleep and no other mount/unmount command will work. Expected Results: filesystem should be unmounted! Additional info: I'm using a Escalade 6000 with 8x80GB disks. The system worked fine with the previous 2.4.2 kernel. However after the update to the latest kernel the system refused to unmount the RAID disk and several problems with the filesystem on that disk manifest themselves (disappearing files etc.). The problem seems to be fixed in the latest RawHide kernel (2.4.5-0.4) but that kernel won't compile under 7.1 (even with the gcc update to 88: it gives a -fno-merge-constants error) and I'd like to disable the CONFIG_REISERFS_CHECK flag.
Please check bug 45628 for the patch against reiserfs there. It should make it work again.
