Hi, I enabled pg_autoscaler on a specific pool ssd. I failed to increase pg_num / pgp_num on pools ssd to 1024: root@ld3955:~# ceph osd pool autoscale-status POOL SIZE TARGET SIZE RATE RAW CAPACITY RATIO TARGET RATIO BIAS PG_NUM NEW PG_NUM AUTOSCALE cephfs_metadata 395.8M 3.0 118.9T 0.0000 4.0 8 off hdb_backup 713.2T 3.0 1354T 1.5793 1.0 16384 off nvme 0 2.0 23840G 0.0000 1.0 128 off cephfs_data 1068G 3.0 118.9T 0.0263 1.0 32 off hdd 733.9G 3.0 118.9T 0.0181 1.0 2048 off ssd 1711G 2.0 27771G 0.1233 1.0 1024 on The target size for this pool is correctly set to 1024: root@ld3955:~# ceph osd pool ls detail pool 11 'hdb_backup' replicated size 3 min_size 2 crush_rule 1 object_hash rjenkins pg_num 16384 pgp_num 10977 pgp_num_target 16384 last_change 344888 lfor 0/0/319352 flags hashpspool,selfmanaged_snaps stripe_width 0 pg_num_min 8192 application rbd removed_snaps [1~3] pool 59 'hdd' replicated size 3 min_size 2 crush_rule 3 object_hash rjenkins pg_num 2048 pgp_num 2048 last_change 319283 lfor 307105/317145/317153 flags hashpspool,selfmanaged_snaps stripe_width 0 pg_num_min 1024 application rbd removed_snaps [1~3] pool 60 'ssd' replicated size 2 min_size 2 crush_rule 4 object_hash rjenkins pg_num 512 pgp_num 512 pg_num_target 1024 pgp_num_target 1024 autoscale_mode on last_change 341736 lfor 305915/305915/305915 flags hashpspool,selfmanaged_snaps,creating stripe_width 0 pg_num_min 512 application rbd removed_snaps [1~3] pool 62 'cephfs_data' replicated size 3 min_size 2 crush_rule 3 object_hash rjenkins pg_num 32 pgp_num 32 last_change 319282 lfor 300310/300310/300310 flags hashpspool stripe_width 0 pg_num_min 32 application cephfs pool 63 'cephfs_metadata' replicated size 3 min_size 2 crush_rule 3 object_hash rjenkins pg_num 8 pgp_num 8 last_change 319280 flags hashpspool stripe_width 0 pg_autoscale_bias 4 pg_num_min 8 recovery_priority 5 application cephfs pool 65 'nvme' replicated size 2 min_size 2 crush_rule 2 object_hash rjenkins pg_num 128 pgp_num 128 last_change 319281 flags hashpspool stripe_width 0 pg_num_min 128 application rbd However there's no activity on the cluster regarding pool ssd, means the pg_num is not increasing. The cluster is working for another pool hdb_backup though; the pg_num of this pool was modified to 16384 recently (to be precise on Monday). What makes things worse is that now I cannot increase pg_num (or pgp_num) manually. root@ld3955:~# ceph osd pool get ssd pg_num pg_num: 512 root@ld3955:~# ceph osd pool get ssd pgp_num pgp_num: 512 root@ld3955:~# ceph osd pool set ssd pg_num 1024 root@ld3955:~# ceph osd pool get ssd pg_num pg_num: 512 How can I increase pg_num / pgp_num of pool ssd?
