>From the PVE GUI, when I create one VM, and setting the "Hard disks"
of  one new VM, I saw the  "Avail" and "Capactivy" of rdb pool are all
zero. Is it not correct for my ceph cluster settings?
I just want to check the ceph cluster whether is ready for test
environment. The method I thought is to use the host of PVE cmd line
to check that. Is there any other method? thanks
