As the command outputs below show, ceph-iso_metadata consume 19TB
accordingly to ceph df, how ever, the mounted ceph-iso filesystem is
only 9.2TB big.
The values nearly add up.
ceph-vm has 2.7 TiB stored and 8.3 TiB used (3x replication).
ceph-iso_data has 6.1 TiB stored and 19 TiB used (3x replication).
Your total capacity is 44 TiB, used is 27 TiB (19 + 8.3), leaving 17 TiB
capacity. Divided by 3 is ca 6 TiB. Your max avail space for the pools
is only 3 TiB.
AFAIK the available space computation takes data distribution and
nearfull ratio (85%) into account.

How are the individual OSDs used?
Can you post the output of "ceph osd df tree"?
"df -h" will show an artificial filesystem size which is the sum of the
used space and the available space of the CephFS data pool. I.e. 6.1 TiB
+ 3.0 TiB makes a df size of 9.2 TiB.
