Description of problem: The default value for the compression parameter "ms_osd_compression_algorithm" is assigned to four different algorithms. This is a bit confusing as we donot know which algorithm is in use by the OSDs. The OSDs choose the preferred algorithm based on mutual understanding between OSDs. [ceph: root@magna052 ceph]# ceph config get mon ms_osd_compression_algorithm snappy zlib zstd lz4 Version-Release number of selected component (if applicable): ceph version 17.2.5-16.el9cp (4d057f2235421ac73034c5e40dbe98f309164079) quincy (stable) How reproducible: Frequently Steps to Reproduce: 1. Install cluster with 6.0 build 2. Execute "ceph config get mon ms_osd_compression_algorithm" command Actual results: The ms_osd_compression_algorithm option have default value set to "snappy zlib zstd lz4" list of algorithms. Expected results: The ms_osd_compression_algorithm option should have default value set to either of snappy, zlib, zstd, lz4 algorithms. Additional info: Refer BZ#2152449
