Disks are not added to data store Capacity in VSan

I have 3 hosts which are in one cluster, each host has an SSD and 4 magntic drives, during VSan I can see the disk groups for each host but when creating the Vsan it adds the capacity of one host only, it also indicates warning that disks format are version 5.

I'm using Vsphere 6.5u1 and vcenter 6.5

Hello salkarkhi

Yes a full cluster parition would also explain only seeing the capacity of one node.

- vSAN 6.6 cluster should be using Unicast but settings such as unicastagent lists won't be pushed down from a vCenter version prior to 6.5 U1.

Whether the nodes are clustered and can communicate with all other members can be verified using:

# esxcli vsan cluster get

Hello salkarkhi​,

"I can see the disk groups for each host"

- So Disk-group creation is not an issue.

"it adds the capacity of one host only"

- Where are you verifying this from?

Check from any of the hosts using df -h.

Are all hosts out of Maintenance Mode at the vSphere and vSAN level?

# cmmds-tool find -t NODE_DECOM_STATE -f json  (state: 0 = not in MM)

Are all of your hosts on an identical ESXi/vSAN build?

Did all disks/disk-groups get created as v5 on-disk format?

Update your vCenter to the same (equivalent) or higher build usually clears these messages as v5 didn't exist prior to 6.6.1 (6.5 U1).

Yes they are all out of maintenance mod.

hosts are identical.

yes all disks created as Vsan format v 5.0

i'm not sure his solution is correct but My friend was able to find the solution by converting the vsan from Multicast into unicast using esxcli command.

Thank you
