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: device-mapper-multipath-0.4.9-91.el7
Doc Type: Bug Fix
Doc Text:
Multiple calls to resize a device will each attempt to resize the device, and will correctly report the result Previously, if `multipathd` failed to resize a device, it continued to think that the device had the new size. Subsequent calls to resize the device would report success and not resize the device because `multipathd` thought that it had nothing left to do. With this fix, `multipathd` now resets the device size to the original size if the resize fails. As a result, multiple calls to resize a device will each attempt to resize the device, and will correctly report the result.

Comment 2 Ben Marzinski 2016-06-03 18:44:46 UTC 
When multipath failed the resize, it was still thinking it had the larger size internally.  Thus, when the second resize command happened, it through that it had nothing to do, and returned success. I've made it reset it's size internally, when the resize command fails.
