Hello,
I was migrating several RBDs between the two pools - from replicated to EC.
I have managed to migrate about twenty images without any issues, all
realtivelly the same size.
It took generally about an hour to execute and 10 minutes to commit for
each one.
The last image however got stuck on commit at 15% for like three days.
I did check the RBD and it was showing it is residing in a new pool. I
was also able to mount it and use it.
I have thus decided to CTRL+C the commit assuming maybe the terminal
session have expired while I didn't check the trash.
Now I have this image sitting in the trash saying it can't be deleted
and saying it is still being migrated.

Has anyone experienced this and if so, will waiting more resolve this or
is there some workaround I can try?
Thank you.
Best regards,
Jozef.
