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the product is no longer active in Red Hat Bugzilla.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.

Inflated VMs
Description of problem:
When using sparse LV - image keeps inflating beyond virtual size until there is no more room in the storage
In the attached, screenshot the inflated VMs Win7-1 and Win7-2 are derived from the same template as Win7-serv - but only these two have inflated.
The difference:
Both inflating VMs are running on a non SPM host, while the reasonable size VM is on the SPM host
Both inflating VMs are virtual desktops while the other is a virtual server.
Version-Release number of selected component (if applicable):

The crux of the issue is that libvirt does not refresh the reported physical size after lvextend:
# virsh domblkinfo 20c0d64c-d706-439a-a39b-9ced382004f0 /rhev/data-center/2c765f7a-2cf1-4025-a107-2c76d44af6a9/5235507a-a6c7-4ec1-a34e-4f7f754a1230/images/4a79ca7d-371d-4a9b-8f8d-a0010b005f26/8e714d9f-b83c-47b5-9d70-8dbae7f8ea13

to solve this quickly and efficiently, vdsm will use its own sense of the physical size when emulating the high write event.
