[SOLVED] Resize CephFS

[some-admins]

Hello,

I changed the pg_num of my BRD-pool and CephFS-Data-Pool with the intent to migrate free space from one to the other. But it seems like this did not have any effect on the available space.

px01:~$ sudo ceph osd pool autoscale-status
POOL              SIZE TARGET SIZE RATE RAW CAPACITY  RATIO TARGET RATIO EFFECTIVE RATIO BIAS PG_NUM NEW PG_NUM AUTOSCALE
cephfs_metadata 326.8M              3.0       28615G 0.0000       0.0050          0.0050  4.0     16            warn     
rbd_pool         3279G              3.0       28615G 0.3438       0.6950          0.6950  1.0    256            warn     
cephfs_data      2343G              3.0       28615G 0.2457       0.3000          0.3000  1.0    128            warn

I expected a change here:



Do I miss something?

Greetings

The number of placement groups does not affect the pool size at all.

Thank you. Deleting stuff in CephFS was enough to make space in the RBD-Pool.
