Ceph Jewel 10.2.10, with 3 OSDs, OSD based replication rules (min 1, max 10) Linux Kernel 4.14.19 We have an older ceph cluster which uses only 2/1 replication rules (min_size = 1, size = 2) for the cephfs_data and metadata pools. The total raw capacity of the cluster is 5.5T. The pools themselves report the expected "MAX AVAIL" value of about 2.6T when using "ceph df". However, when cephfs is mounted on the OS and we use the system 'df' command, it shows that the max size of the cephfs filesystem is the full capacity of the cluster (5.5T) when we use the "df -h" command. We are expecting to see the 2.6T value, any idea why it reports the full cluster capacity instead of the max available for the cephfs data pool? thanks!
