Hi, increasing pg_num for a cache pool gives you a warning, that pools must be scrubed afterwards. Turns out If you ignore this flushing and evicting will not work. You realy should do something like this: for pg in $(ceph pg dump | awk '$1 ~ "^<pool-id>." { print $1 }'); do ceph pg scrub $pg; done After just a few seconds my pool started flushing and evicting again.
