Hi,
I have an old ceph cluster and have upgraded recently from Luminous to
Nautilus. After converting to Nautilus I decided it was time to convert to
bluestore.
Before I converted the cluster was healthy but after I have a HEALTH_WARN
#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 ['data', 'metadata', 'rbd', 'images', 'locks'] overcommit
available storage by 1.244x due to target_size_bytes 0 on pools []
POOL_TARGET_SIZE_RATIO_OVERCOMMITTED 1 subtrees have overcommitted pool
target_size_ratio
Pools ['data', 'metadata', 'rbd', 'images', 'locks'] overcommit
available storage by 1.244x due to target_size_ratio 0.000 on pools []
I started with a target_size ratio of .85 on the images pool and reduced it
to 0 to hopefully get the warning to go away. The cluster seems to be
running fine, I just can't figure out what the problem is and how to make
the message go away. I restarted the monitors this morning in hopes to fix
it. Anyone have any ideas?
Thanks in advance
