Description of problem:
Making upgrade to 2.4.3-12 kernel, if I have a reiserfs partition, I
can't umount it.
Steps to Reproduce:
1. Upgrade do Kernel 2.4.3-12 from RedHat Errata, boot it.
2. If you wanna, upgrade to mount-2.11b-3 too, no matters.
3. Format a partition with reiserfs (mkreiserfs /dev/XXXX)
4. Mount the partition.
5. Try Umount the partition.
Actual Results: umount never return, don't umount.
Expected Results: umount the partition.
It may cause loss of data on computer shutdown, when umount can't
umount the reiserfs, and keep other open, the only way is pressing
Could you try the 2.4.3-15 kernel I put on
That should have a fix for this.
This bug is the same as 45628. Should close this and mark as duplicate of 45628.
I tried kernel 2.4.3-15. It worked for me. Does this kernel include the ReiserFS/NFS compatibility patch for knfsd?
no, that patch wasn't ready for mainstream in the 2.4.3 timeframe.
In 2.4.3-15, did you just enable CONFIG_REISERFS_CHECK instead of applying a
patch for umount? Is this going to cause a big performance hit?
I didn't touch that setting in -15; just fixed the real bug.
There now is a -16 up (same place) with a fix for the dmfe NIC driver; if/when I
make a -17 I can disable this check; however Chris Mason (SuSE, major reiserfs
contributor) doesn't think it makes a lot of performance difference, except in
strange benchmark cornercases.
