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). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Fixed In Version: lvm2-2.02.125-1.el7
Doc Type: Bug Fix
Doc Text:
Before, the blk-availability.service was not ordered with respect to iSCSI services properly. The blk-availability service is responsible for handling shutdown of dm-based block devices (including LVM and multipath devices) and such improper ordering could have caused the iSCSI devices to be detached on system shutdown sequence before dm-based devices were deactivated, ending up with possible IO errors then. The blk-availability.service systemd unit is now properly ordered so that it's always executed before iscsi-shutdown.service responsible for detaching iSCSI devices.

Red Hat Product Errata RHBA-2015:2147 0 normal SHIPPED_LIVE lvm2 bug fix and enhancement update 2015-11-19 11:11:07 UTC

Description Peter Rajnoha 2015-03-13 11:32:19 UTC 
RHEL uses a separate iscsi-shutdown.service for iscsi session logout in contrast to upstream's iscsi.service. Add After=iscsi-shutdown.service to blk-availability.service that is responsible for deactivating dm-based devices. This should be done before any iscsi devices underneath are logged out.

(I expect the iscsi-shutdown will eventually get upstream as well.)

The patch is here:
