Upgraded from PVE 6.0.x to 6.1-7, cannot migrate VMs due to Ceph error?

Hi all,

I just recently updated my cluster from 6.0 to 6.1-7. I currently have 4 nodes, each with 8 OSDs and storage called RBD which contains all of my disk images. The VMs are working fine, but when I try to migrate one to another node, I get the following error:

2020-02-06 12:36:11 starting migration of VM 112 to node 'naboo' (192.168.77.2)
2020-02-06 12:36:11 ERROR: Failed to sync data - rbd error: rbd: listing images failed: (2) No such file or directory
2020-02-06 12:36:11 aborting phase 1 - cleanup resources
2020-02-06 12:36:11 ERROR: migration aborted (duration 00:00:00): Failed to sync data - rbd error: rbd: listing images failed: (2) No such file or directory
TASK ERROR: migration aborted

I'm not sure what to do at this point, I tried googling for an answer but found nothing. The Ceph cluster is completely healthy based on the output from ceph -s.

Any suggestions on things to try or check? Thanks!

Go ahead and marked this SOLVED. I ran these commands:

rbd ls -l RBD and saw that an unused disk image was out there from a VM I had created new disks on. I went ahead and issued a rbd rm <disk image name> -p RBD and that cleaned it up.

I can now do migrations again.
