Hi,
Ceph Version = 12.2.8
8TB spinner with 20G SSD partition
Perf dump shows the following:
"bluefs": {
"gift_bytes": 0,
"reclaim_bytes": 0,
"db_total_bytes": 21472731136,
"db_used_bytes": 3467640832,
"wal_total_bytes": 0,
"wal_used_bytes": 0,
"slow_total_bytes": 320063143936,
"slow_used_bytes": 4546625536,
"num_files": 124,
"log_bytes": 11833344,
"log_compactions": 4,
"logged_bytes": 316227584,
"files_written_wal": 2,
"files_written_sst": 4375,
"bytes_written_wal": 204427489105,
"bytes_written_sst": 248223463173
Am I reading that correctly, about 3.4GB used out of 20GB on the SSD, yet 4.5GB
of DB is stored on the spinning disk?
Am I also understanding correctly that BlueFS has reserved 300G of space on the
spinning disk?
Found a previous bug tracker for something which looks exactly the same case,
but should be fixed now:

Thanks,
Nick
