TARGET RATIO

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello to all,

I read the documentation https://docs.ceph.com/en/latest/rados/operations/placement-groups/

In this part the page placement-groups this part:

*TARGET RATIO*, if present, is the ratio of storage that the administrator has specified that they expect this pool to consume relative to other pools with target ratios set. If both target size bytes and ratio are specified, the ratio takes precedence.

For now my pools and ratios is :

ceph osd pool autoscale-status
POOL                                 SIZE          TARGET SIZE RATE  RAW CAPACITY   RATIO  TARGET RATIO  EFFECTIVE RATIO  BIAS PG_NUM  NEW PG_NUM  AUTOSCALE device_health_metrics      21849k        500.0G 2.0        106.4T 0.0092      1.0       8 on vm.pool                             2734G            3.0        106.4T                  0.0753 2.0000           0.8924                      1.0 512                                       on cephfs_data                                0             2.0        106.4T                  0.0000 0.2000           0.0892                      1.0 128                                       on cephfs_metadata             28531k         500.0G 2.0        106.4T 0.0092              4.0      32 on


If I understand  right I can set the Ratio =< 3 or more and is right ratio for this pool? I'am correct?

This pool is for VM disks data.
