Description Bryn M. Reeves 2010-04-22 17:32:50 UTC

Description of problem:
The fix for bug 511271 deleted the lines in the iscsi init script that disabled network shutdown:

> This is the diff of two versions of /etc/init.d/iscsid:
> $ diff iscsid.iscsi-initiator-utils-6.2.0.871-0.14.el5.i386.rpm \
> iscsid.6.2.0.871-0.10.el5 
> 
> 18a19,26
> > 	echo -n $"Turning off network shutdown. "
> > 	# we do not want iscsi or network to run during system shutdown
> > 	# incase there are RAID or multipath devices using
> > 	# iscsi disks
> > 	chkconfig --level 06 network off
> > 	rm /etc/rc0.d/*network
> > 	rm /etc/rc6.d/*network
> >    

This was done to avoid a conflict with readonly root environments but causes a regression of bug 209523, (I/O errors and hangs when shutting down a system using iSCSI).

Version-Release number of selected component (if applicable):
iscsi-initiator-utils-6.2.0.871-0.16.el5

How reproducible:
100%

Steps to Reproduce:
1. Configure a system to use iscsi-initiator-utils to access storage
2. Shutdown the host while the iscsi storage is in use

  
Actual results:
Network shutdown scripts shut down the iSCSI interfaces before file systems are unmounted and the iSCSI service itself is shut down, leading to I/O errors.

Expected results:
System should not hang or produce I/O errors on shutdown.

Fix component.

Comment 5 Mike Christie 2010-05-27 23:24:51 UTC

This is a s dup of
https://bugzilla.redhat.com/show_bug.cgi?id=583218

Which bz do you want to use? The other one is not setup for z stream yet.

The fix is not easy when also supporting boot and existing solutions and the chkconfig read-only issue.

Comment 6 Mike Christie 2010-05-27 23:27:02 UTC

One question.

Should I be able to just run "chkconfig --level 06 network off" in the rpm install section? Then on later boots the network shutdown should be off or is there something that resets that on each boot?
