We will increase the number of placement groups for one of the CEPH infrastructures that hosts images and snapshots.
So as not to affect performance, we will launch the operations over several nights, from 7 July until 12 July. Rebalance tasks will run after 22.00 CEST.
No impact on the performance of disks or instances.
