cancel export task - no qemu-img process on host
Hi, i tried to find way how to cancel hanged export task. I found that there should be some hidden possibility, but it is still not released and i cannot find how to allow it. i found how to remove this task directly from pg database on engine, but i am not sure if this also will unlock that VM. i cannot kill it by qemu-img process, because this process is not running. stucked VM is ubuntu 20.04 with 3 disks 20 + 80 + 300GB . Already running more than 12 hours and still did not start making ova file (checking in export folder) . qemu-img process on the host is missing . i tried to export smaller VM 7GB and it was successfully done by 2 minutes. During export qemu-img process was running on the host. Thank you for any help. BR jan
last log from /var/log/ovirt-engine/ova for this VM: 2022-09-22 03:35:41 CEST - TASK [ovirt-ova-export-pre-pack : Allocating the temporary path for the OVA file] *** and then many hours no change.
no qemu-img process ,, but i found that it hanged on : root 30850 0.0 0.0 114740 2924 ? S Sep21 0:00 /bin/sh -f /usr/sbin/xfs_mkfile -n 81257582592 /mnt/transfer/ovirtbackupexample.ova.tmp root 30853 0.0 0.0 152756 2300 ? D Sep21 0:00 /usr/sbin/xfs_io -p xfs_mkfile -ft -c truncate 81257582592 -- /mnt/transfer/ovirtbackupexample.ova.tmp strace showed,that these processes do nothing,,, so i killed 30850 . after kill, file /mnt/transfer/ovirtbackupexample.ova.tmp was created (strange ,i know) ,,, task failed,, snapshot from VM was removed automatically and VM was unlocked. So issue was fixed. After this i removed already existed snapshot (forgotten , few months) on VM and try export again ... export was succesfull and also import was smoothly. when i will have free time, i will try to do export of VM with already existed snapshot.
