Hi,
I want to create an optimizer plan on each pool.
My cluster has multiple crush roots, and multiple pools each
representing a specific drive (HDD, SSD, NVME).
Some pools are balanced, some are not.
Therefore I want to runĀ optimizer to create a new plan on specific pool.
However this fails for any pool with this error message:
root@ld3955:~# ceph balancer optimize hdd-plan hdd
Error EALREADY: Unable to find further optimization, or pool(s)' pg_num
is decreasing, or distribution is already perfect
root@ld3955:~# ceph balancer optimize ssd-plan ssd
Error EALREADY: Unable to find further optimization, or pool(s)' pg_num
is decreasing, or distribution is already perfect
root@ld3955:~# ceph balancer optimize hdb_backup-plan hdb_backup
Error EALREADY: Unable to find further optimization, or pool(s)' pg_num
is decreasing, or distribution is already perfect
root@ld3955:~# ceph osd pool ls
hdb_backup
hdd
ssd
nvme
cephfs_data
cephfs_metadata
What is causing this error?
THX
