  • 1.  Converting a Local Datastore to vSAN Storage?

    Posted Feb 04, 2024 07:36 PM

    I've created three ESXi hosts and given each of them a 64 GB local datastore for the ESXi operating system and a slightly larger 128 GB local datastore for storing small VMDK's.

     

    Now I'd like to convert the larger datastore to vSAN.

     

    Will it be enough to simply unmount the datastore by following this simple procedure? Or will I need to do more before I can begin using it as backing device for vSAN?

     

    TIA,

    there is no conversion option, for this to work you would need at least 2 hosts and a witness (or preferably just 3 hosts) with 1 NVMe device for vSAN ESA, or a caching and capacity device for vSAN OSA. Also, these devices need to be directly accessible, so it cannot be a RAID-1 device or something like that. The devices will also need to be empty, so no partitions etc.
