Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
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.

Bug 1600662

Summary: Growing physical size should not suspend vdo device when the size is equal [rhel-7.5.z]
Product: Red Hat Enterprise Linux 7 Reporter: Jaroslav Reznik <jreznik>
Component: kmod-kvdoAssignee: Matthew Sakai <msakai>
Status: CLOSED ERRATA QA Contact: Jakub Krysl <jkrysl>

Priority: high    
Version: 7.5CC: awalsh, bgurney, jkrysl, jreznik, msakai, rhandlin

Whiteboard:
Fixed In Version: 6.1.0.181 Doc Type: If docs needed, set a value
Doc Text:
Previously, VDO volumes were unable to grow if the underlying block device increased in size while the system was powered off or the VDO volume was offline. With this update, VDO correctly checks the requested size and the current size of the device, and, as a result, the described problem no longer occurs.
