I'm managing an ESXi 5.1 box that has two RAID5 virtual disks. One is empty, the other has a VMFS5 datastore using the entirety of the space. I want to expand that datastore to utilize the space on the empty virtual disk, but don't know the best way of doing that.
1. vSphere will let me expand it the way it's currently configured, leaving me with a single datastore spanning two virtual disks. Is that a good idea, or would it be detrimental to performance? Can it be done live?
2. If that's a bad idea or can't be done live, can I delete the empty virtual disk, add the drives to the other array, then expand the datastore? Can that be done live?
Any help is appreciated. Thanks!
