Description of problem:
I use the exim MTA (self-compiled). The mailbox directories are on ReiserFS/aic7xxx_mod/IBM ESS ("Shark"); the spool directory
the logs and the delivery journal file) is on ext2/ips/IBM ServerRAID. When delivering a short test message to an alias that expands to
users, the delivery process goes into a 'D' wait as does kupdated. Usually one of the lock files is left behind.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Set up /var/spool/mail on ReiserFS, leave /usr/local on ext2.
2. Install exim from tarball.
3. Create mail alias for 100 users.
4. Send short message to mail alias.
Actual Results: Delivery process (exim) goes into 'D' wait, does not terminate.
kupdated goes into 'D' wait.
any process that tries to update the disk goes into 'D' wait. This includes /sbin/shutdown. Time to flip the power switch.
Expected Results: Delivery should terminate normally.
Kernel 2.4.3-15 works fine.
Sorry, it looks like I was using a bad version of the ReiserFS quota patches. I believe I have kernel-2.4.9-6 working OK with the latest patches.
