RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit).

3.1 beta2 - VDSM: lock is not released on vm that is shut down while storage is not accessible - moving vm to a different storage domain will result in vm getting stuck in image locked forever
Description of problem:
if you shut down a vm while storage domain is not accessible we will not release the lock on the vm and if we try to move it to a different domain the vm will be stuck in image locked forever.
I used iscsi storage domain consisting of 2 luns from different storage servers. I blocked only one of the storage servers from the host using iptables.
also, this does not happen in upstream.
Version-Release number of selected component (if applicable):
vdsm-4.9-112.6.el6_2.x86_64
How reproducible:
100%
Steps to Reproduce:
1. create DC with two SD (my master domain consisted of luns from 2 different storage servers).
2. run vm and block connectivity to one of the storage servers from the host using iptables
3. when vm pauses stop it and restore SD connectivity
4. move vm to a different domain.
Actual results:
vm will be stuck in image lock forever
Expected results:
we should be able to move vm
