Consolidating disks – unable to access file since it is locked

Had a vm which had flagged up as requiring disk consolidation
Attempting consolidation failed with the error ‘ Unable to access file since it is locked’

The error stack showed the following : msg.fileio.lock

Solution:

Storage vMotion the disk to another data store and reattempt consolidation, this time it has cleared the locks and works. Nice and quick one, although not obvious.
Alternatively you could find the host that has a lock on the file and restart hostd, but depending on the environment this method can be a lot faster.
