vSAN Health Error

[M4T]

Hi community,

i have installed a vSAN cluster of 4 hosts. but the "vsan datastore doesn't have capacity" is an error which i'm receiving which i'm guessing is because of this error as everything else is green.

Hello Matto,

If the other nodes are clustered properly (and have Disk-Groups created then they should see vsandatastore to be of size (can easily be validated via SSH with df -h).

Regarding the non-clustered node: check that this has a vSAN-enabled vmk on the same subnet as the other nodes have this, with correct MTU and that it can reach the other nodes (e.g. with 1500 MTU: # vmkping -I <vSAN vmk> -s 1472 -d <destination vSAN vmk IP>

Are all your hosts in maintenance mode ?  Datastore will be 0tb if they are.
