Hi Jeremy, you might want to try RocksDB's disable_auto_compactions option for that. To adjust rocksdb's options one should edit/insert bluestore_rocksdb_options in ceph.conf. E.g. bluestore_rocksdb_options = "disable_auto_compactions=true,compression=kNoCompression,max_write_buffer_number=4,min_write_buffer_number_to_merge=1,recycle_log_file_num=4,write_buffer_size=268435456,writable_file_max_buffer_size=0,compaction_readahead_size=2097152,max_background_compactions=2,max_total_wal_size=1073741824" Please note bluestore specific defaults for rocksdb settings are re-provided to make sure they aren't reset to rocksdb's ones. Hope this helps. Thanks, Igor On 12/21/2020 2:56 AM, Jeremy Austin wrote:

Will attempt to disable compaction and report.
Not sure I'm doing this right. In [osd] section of ceph.conf, I added periodic_compaction_seconds=0
and attempted to start the OSDs in question. Same error as before. Am I setting compaction options correctly?
