Title:
luminous: bluestore rocksdb max_background_compactions regression in
12.2.13
Status in Ceph:
Unknown
Status in ceph package in Ubuntu:
Invalid
Status in ceph source package in Bionic:
Fix Committed
Bug description:
There is a potential regression in the rocksdb
max_background_compactions change in the 12.2.13 point release that is
in bionic-proposed.
https://tracker.ceph.com/issues/44937 was raised as the rocksdb
version in the bionic ceph source does not contain:
https://github.com/facebook/rocksdb/pull/3926
which ensures that any overlap between background compactions is
detected and handled.
We either need to revert to a single background compaction as the
default setting, or pick the fix into the rocksdb source in
src:ceph/bionic
