3 Cluster Management nodes has 70GB storage for each and running cifs share service.
2 storage nodes nodes has 70GB storage for each and running cifs share service.
In Webgui show me has 350GB for this Cluster Pool (70GB * 5). But When I connect to the server and map the driver just show me 108GB(I dont know why ) at all. So Im very confused why or its normal? Thanks a lot.

The 108 GB is size available on the cephfs data pool taking into account the 3x replication on that pool.

Thanks.

for your prev questions: the storage you add ( 350 GB ) is available for storage pools. you pool has 3x replication so if you write 1 GB it will actually use 3 GB for redundancy. So divide 350 by 3 is what you can write
