645% Clean PG's in Dashboard
Hi, I've upgraded to Nautilus from Mimic a while ago and enabled the pg_autoscaler. When pg_autoscaler was activated I got a HEALTH_WARN regarding: POOL_TARGET_SIZE_BYTES_OVERCOMMITTED 1 subtrees have overcommitted pool target_size_bytes Pools ['cephfs_data_reduced', 'cephfs_data', 'cephfs_metadata'] overcommit available storage by 1.460x due to target_size_bytes 0 on pools [] POOL_TARGET_SIZE_RATIO_OVERCOMMITTED 1 subtrees have overcommitted pool target_size_ratio Pools ['cephfs_data_reduced', 'cephfs_data', 'cephfs_metadata'] overcommit available storage by 1.460x due to target_size_ratio 0.000 on pools [] Both target_size_bytes and target_size_ratio on all the pools are set to 0, so I started to wonder why this error message appear. My autoscale-status looks like this: POOL SIZE TARGET SIZE RATE RAW CAPACITY RATIO TARGET RATIO BIAS PG_NUM NEW PG_NUM AUTOSCALE cephfs_metadata 16708M 4.0 34465G 0.0019 1.0 8 warn cephfs_data_reduced 15506G 2.0 34465G 0.8998 1.0 375 warn cephfs_data 6451G 3.0 34465G 0.5616 1.0 250 warn So the ratio in total is 1.4633.. Isn't 1.0 of the combined ratio of all pools equal of full? I also enabled the Dashboard and saw that the PG Status showed "645% clean" PG's. This cluster was originally installed with version Jewel, so may it be any legacy setting or such that causing this?

No, this seems to be a genuine bug in the dashboard - we're tracking this here: https://tracker.ceph.com/issues/41536 and a fix is in the works: https://github.com/ceph/ceph/pull/30343 Lenz -- SUSE Software Solutions Germany GmbH - Maxfeldstr. 5 - 90409 Nuernberg GF: Felix Imendörffer, HRB 247165 (AG Nürnberg)
