Description Roger Moore 2001-06-26 20:41:47 UTC

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.

Comment 1 Arjan van de Ven 2001-06-26 20:45:57 UTC

Please check bug 45628 for the patch against reiserfs there.
It should make it work again.
