Hello,
How much disk space per disk-groups is currently used on this vSAN datastore? (via RVC > vsan.disks_stats)
Where are you seeing this 1.44TB/1.46TB used?
The first things to check if you suspect a disk issue are:
- Cluster > Monitor > Health > Look for cluster or disk issues under the drop-down sub-checks
- SSH to the host and run # esxcli vsan storage list
If you are seeing disks with 'In CMMDS: false' then yes you have a disk issue.
If you want to see what LSOM-components are located on a disk then check using the capacity drive UUID from the above command:
#cmmds-tool find -t DOM_OBJECT | grep <UUID of disk>
