CEPH Storage Disk Usage Always 100%: ACS:4.16.1

[Midhun Jose <mi...@assistanz.com.INVALID>]

Hi All 

I have integrated cloudstack 4.16.1 with CEPH cluster as primary storage. One issue that I face is that the actual disk usage for the volume is not getting updated. The Utilization is always 100%. The 'Physical Size' is getting updated as the full provisioned size and disk stats are always 0. The provisioning is thick only, and in CEPH admin I am getting correct value of used size. 
Any comments on this?

Hi Midhun,

In my ceph environment with cloudstack 4.18 (latest main),  The disk
read/write iops/bps are all 0. I have created a github issue:
https://github.com/apache/cloudstack/issues/7036

As you can see on the screenshot, the Utilisation looks good.
