If you have luns setup before you do the iscsi login, then do #2, #4, and #5, do you hit the same problem? If so the problem is that the session are not being shutdown during reboot/shutdown. If the disks need a cache sync to be sent during kernel shutdown then we hang on that command because the network is down at this time. I am working on a fix here: https://bugzilla.redhat.com/show_bug.cgi?id=583218 My original fix did not handle iscsi root properly, so still working on it.

Mike; #3 doesn't have to do anything with it. We did test it where the luns were already created before doing #2, #4 and #5 and we hit the same issue. also we did test the workaround provided in 583218 and it worked. below are the steps: 1) Established iSCSI sessions. 2) Created volumes and mapped. 3) Ran IO for sometime and stopped. 4) Logged out all sessions using the command iscsiadm –m node –U all 5) Rebooted the host. The host rebooted without any issues. So, does that mean that this bug is a dup of 583218? (In reply to comment #2) > So, does that mean that this bug is a dup of 583218? Yep, dup. *** This bug has been marked as a duplicate of bug 583218 *** |
