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.
+++ This bug was initially created as a clone of Bug #1414049 +++
Description of problem:
At the moment qemu-img allows you to specify how image file should be allocated during creation, using 'preallocation' option. Onr of possible choices is using 'falloc' option to fully allocate image file using fallocate(2) call.
Unfortunately, resize operation only supports sparse resizing and there is no way to preallocate new disk space during resize operation.
It would be nice, if qemu-img will support preallocation during resize with fallocate(2) and, possibly, some fallback preallocation method.
Hi Max,
As the flag rhel-7.4.0? is set, qe wonder to know whether the issue will be fixed in rhel 7.4? Then qe can add it to RHEL 7.4 test plan for disk format. Thanks.
Hi pingl,
I'm most certainly working on getting it into 7.4. Considering that the development phase ends on March 28 and upstream qemu is currently occupied with preparing the 2.9 release, it may very well slip to 7.5, however.
So I cannot give a definite response but if I had to decide I would guess it won't make it into 7.4 (since it's an RFE).
Max
