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. --- Additional comment from kwolf on 2011-01-19 09:32:06 EST --- qcow2 only supports growing images, not shrinking. So this is the expected result (except that qemu-io doesn't get the right error message). --- Additional comment from szhou on 2011-01-19 21:30:23 EST --- (In reply to comment #10) > qcow2 only supports growing images, not shrinking.

Kevin, would you prefer fix this error message on this bug or prefer open a separate one? --- Additional comment from szhou on 2011-01-24 05:38:26 EST --- (In reply to comment #10) > qcow2 only supports growing images, not shrinking. So this is the expected > result (except that qemu-io doesn't get the right error message). According to comment 9 and comment 10, this issue has already been fixed. And I will open another bug to track error message issue.
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.
move to verified based on comment#6.
