Hi, I found that the pg_num and pgp_num for meta data pool was too small and then increased them. Then I got "300 pgs stuck unclean". $ ceph -s cluster a4d0879f-abdc-4f9d-8a4b-53ce57d822f1 health HEALTH_WARN 248 pgs backfill; 52 pgs backfilling; 300 pgs stuck unclean; recovery 58417161/113290060 objects misplaced (51.564%); mds0: Client physics-007:Physics01_data failing to respond to cache pressure Is it critical? thanks, Erming -- --------------------------------------------- Erming Pei, Ph.D Senior System Analyst; Grid/Cloud Specialist Research Computing Group Information Services & Technology University of Alberta, Canada Tel: +1 7804929914 Fax: +1 7804921729 --------------------------------------------- |
