@zachary715 said in Shrink VMDK - VMware:
Option 2 would be to migrate the VM to a different datastore with dissimilar block size and specify "Thin Provision" when moving. If you have or can create a datastore with a block size different than your current config, then you can do this without downtime.
Funny you mention that. I had forgotten about that method until this morning. I ended up using that method on the server (after creating a datastore using NFS share on a Synology appliance), using it strictly as a backup for a couple days to make sure things are good. I'll likely not use the conversion in the future; though they both took around the same amount of time to complete, the conversion was such a pain.
