snap_create for combination of qcow2 and ssh TM

Development
1

Hello,

i’ve started using the offline disk snapshots on ONE 4.14.2 and i’ve encountered some troubles. My image datastore uses qcow2 TM driver. However my system datastores use SSH TM driver. When I wanted to create a snapshot, it always failed because it was trying to execute ‘readlink’ on the ONE frontend where the image of the VM was not available.

I had to bypass it by modifying the qcow2 TM driver - the change is somewhere around line 79 - just to make readlink execute on the remote host (addition of the backslash):
PREVIOUS_SNAP=$(readlink $SYSTEM_DS_DISK_PATH)

Now I can both create and revert snapshots.

Is this a bug or have I done something wrong?

Hi,

It may be a bug. Please open a ticket at http://dev.opennebula.org with the description and a link to this thread, this way it won’t get buried in the forum.

Thanks.
