I am attempting to add space to a hard disk on a VM. When I attempt to increase the space of the hard disk, I receive the following error "Insufficient disk space on datastore. The disk extend operation failed: There is not enough space on the file system for the selected operation." The hard disk is 675 GB and I am attempting to increase it to 700 GB. The hard disk is part of a datastore that has 125 GB of free space. Any help would be greatly appreciated.
Hello,
The thread below seems to be old but see if it can be used as a guidance:
Cant add more disk space, error: "Insufficient disk space on datastore"
Can you vMotion the VM? Are there any snaps?
