Hello,
I have 3 FSTs on CephFS. They each mount a separate subdirectory of the same filesystem and see something like this:
bash-4.2# df -B TB /cephfs
Filesystem 1TB-blocks Used Available Use% Mounted on
10.30.201.3:6789,10.30.202.3:6789,10.30.203.3:6789:/volumes/_nogroup/55e46a89-31ff-4878-9e2a-81b4226c3cb2/test1 4412TB 304TB 4109TB 7% /cephfs
However:
# eos space ls

The space reported by MGM is equal to 3x the real available and used storage amounts. It must be adding up what is reported by each FST.
4412 TB * 3 = 13.236 PB
303319 GB * 3 = 909.9 TB
Is there a way to configure the FSTs so I can tell them they are all seeing the same filesystem on CephFS?
(Actually the storage reported by df on the FSTs is also incorrect but that is a separate issue.)
Thanks!
