Description Michael Chan 2010-05-24 18:58:04 EDT
+++ This bug was initially created as a clone of Bug #578005 +++

MTU change (or other network reset events) with active iSCSI sessions will fail.  iSCSI sessions do not recover and resources are leaked.

This upstream patch will fix it:

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=490475a9938f3480e1ab3a67063e547cea41c295

Requesting this to be included in RHEL5.5.z.
Comment 2 RHEL Product and Program Management 2010-05-25 15:32:14 EDT

release.
Comment 7 Jarod Wilson 2010-09-15 10:01:22 EDT
in kernel-2.6.18-221.el5
You can download this test kernel from http://people.redhat.com/jwilson/el5

Detailed testing feedback is always welcomed.

With kernel-2.6.18-221.el5 and 	iscsi-initiator-utils-6.2.0.872-10 (uIP 0.5.15), iSCSI sessions still do not recover after changing MTU sizes.  The problem appears to be uIP-related since it does work when I add a newer internal version of uIP on top of the above components.
Comment 10 edwardn 2010-10-14 12:58:11 EDT
Slight mistake to the above iscsi-initiator version... it should be iscsi-initiator-utils-6.2.0.872-2.el5.x86_64.rpm (the latest RH5.6 initiator at the moment... http://people.redhat.com/mchristi/iscsi/rhel5.6/iscsi-initiator-utils/).  

Revised:
With kernel-2.6.18-221.el5 and  iscsi-initiator-utils-6.2.0.872-2 (uIP
0.5.15), iSCSI sessions still do not recover after changing MTU sizes.  The
problem appears to be uIP-related since it does work when I add a newer
internal version of uIP on top of the above components.
Comment 11 Mike Christie 2010-10-14 16:33:43 EDT
Hey Edward,

What is still needed? Is iscsi-initiator-utils's uip missing a patch from another bugzilla?
Comment 16 edwardn 2010-11-19 19:54:59 EST
This problem is no longer seen with kernel-2.6.18-232.el5 and iscsi-initiator-utils-6.2.0.872-6.el5.x86_64.rpm (uIP 0.6.2.2).
