Description John Dalbec 2001-10-01 13:28:36 UTC
From Bugzilla Helper:
User-Agent: Mozilla/4.78 [en] (Windows NT 5.0; U)

Description of problem:
I use the exim MTA (self-compiled).  The mailbox directories are on ReiserFS/aic7xxx_mod/IBM ESS ("Shark"); the spool directory 
(contains 
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 
100 
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):
2.4.7-10

How reproducible:
Always

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.

Additional info:

Kernel 2.4.3-15 works fine.

Comment 1 John Dalbec 2001-10-24 13:19:11 UTC
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.
