Hello everybody!
What does this mean?
health: HEALTH_WARN
1 subtrees have overcommitted pool target_size_bytes
1 subtrees have overcommitted pool target_size_ratio
and what does it have to do with the autoscaler?
When I deactivate the autoscaler the warning goes away.
$ ceph osd pool autoscale-status
POOL SIZE TARGET SIZE RATE RAW CAPACITY RATIO TARGET RATIO BIAS PG_NUM NEW PG_NUM AUTOSCALE
cephfs_metadata 15106M 3.0 2454G 0.0180 0.3000 4.0 256 on
cephfs_data 113.6T 1.5 165.4T 1.0306 0.9000 1.0 512 on
$ ceph health detail
HEALTH_WARN 1 subtrees have overcommitted pool target_size_bytes; 1 subtrees have overcommitted pool target_size_ratio
POOL_TARGET_SIZE_BYTES_OVERCOMMITTED 1 subtrees have overcommitted pool target_size_bytes
Pools ['cephfs_data'] overcommit available storage by 1.031x due to target_size_bytes 0 on pools []
POOL_TARGET_SIZE_RATIO_OVERCOMMITTED 1 subtrees have overcommitted pool target_size_ratio
Pools ['cephfs_data'] overcommit available storage by 1.031x due to target_size_ratio 0.900 on pools ['cephfs_data']
Thanks
Lars
