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.

Description Shirley Zhou 2011-01-24 10:48:27 UTC 
Description of problem:
Improper responsive messages when shrinking qcow2 image

Version-Release number of selected component (if applicable):
qemu-kvm-0.12.1.2-2.129.el6.x86_64

+++ This bug was initially created as a clone of Bug #613893 +++

While this bug reproduce when truncate size smaller than initiate size.
# qemu-img create -f qcow2 test.img 2G
Formatting 'test.img', fmt=qcow2 size=2147483648 encryption=off cluster_size=0 
# qemu-io test.img
qemu-io> truncate 1G
truncate: Unknown error 18446744073709551521

BTW this issue does not exist on raw format.

So change status to assigned.

qcow2 only supports growing images, not shrinking. So this is the expected result (except that qemu-io doesn't get the right error message).

Kevin, would you prefer fix this error message on this bug or prefer open a separate one?

According to comment 9 and comment 10, this issue has already been fixed.

And I will open another bug to track error message issue.
Comment 6 Shirley Zhou 2011-02-11 09:11:25 UTC 
Verify this bug with qemu-kvm-0.12.1.2-2.144.el6.x86_64 as following

]# qemu-img create -f qcow2 test.img 2G
Formatting 'test.img', fmt=qcow2 size=2147483648 encryption=off cluster_size=0 
# qemu-io test.img
qemu-io> truncate 1G
truncate: Operation not supported

So this bug has been fixed.
