Thanks Wido.
@ But normally CephFS will be able to use all the space inside your Cephcluster.
So, you are saying even if i see the size for CephFS pools as 55 GB, it can still use whole 600GB (or the available disk) from Cluster?
This is what i have with PGNum = 150 (for Data) and 32 (for Metadata) in my cluster.
Thanks

You can set quotas on CephFS or on the RADOS pool for the CephFS 'data'
(haven't tried the last one though).
But normally CephFS will be able to use all the space inside your Ceph
cluster.
It's not that you can easily just allocate X GB/TB to CephFS.
