Isn't that only the case with full, non-granular heals? And according to
the docs, "full" forces a resync of the entire volume, not just the
out-of-sync files. Seems a bit overkill for anything other than a brick
One question - how do you plan to convert the VM's?

AFAIK, if you enable sharding on a volume, it will only apply to new files.
An easier option might be to enable sharding & then clone the VMs to create
