Hello,
Good day !
1. The "Mounted" status which you see in the vSAN Cluster -> Manage -> Disk management -> Disk Group-> "Operational status" is actually the physical status of the disk.
2. The CMMDS: FALSE indicates the vSAN has unclaimed the disk temporarily from the vSAN datastore due to the above mentioned issues. You can also see this in the same screenshot which you have pasted here.
vSAN Cluster -> Manage -> Disk management -> Disk Group-> vSAN health Status
A working/claimed/mounted disk should be listed here as "Healthy"
-Also when you run df -h on the affected host, you will see reduction in the actual size of the vSAN datastore
3. Re-mount or force mount should allow the disks to be mounted back to the hosts else reboot should get them online.
I hope this answers your question.
Cheers,
Pradeep Venkatesh
