[ovirt-users] Ovirt tasks "stuck"

Hi: A few days ago I attempted to create a new VM from one of the ovirt-image-repository images. I haven't really figured out how to use this reliably yet, and in this case, while trying to import an image, one of my nodes spontaneously rebooted (or at least, it looked like that to ovirt...Not sure if it had an OOM issue or something else). I assume it was the node that got the task of importing those images, as ever since then (several days now), on my management screen under "Tasks" it shows the attempted imports, still stuck in "processing". I'm quite certain its not actually processing. I do believe it used some of my storage up in the partially downloaded images, though (they do show up as GlanceDisk-<numbers>, with a status of "Locked" under the main Disks tab. How do I "properly" recover from this (abort the task and delete the partial download)? Thanks! --Jim
