On January 21st your storage services on some Cloud Instances in our GRA Datacenter will move to the Jewel release 10.2.10 of CEPH (https://ceph.com/releases/v10-2-10-jewel-released/ ).
The maintenance will start at 22:00 AM CET (21:00 UTC) for an estimated duration of 36 hours. During the operation, your storage backend will remain available.
From January 14th you may notice loss of l/O performance on your disks due to a preventive backup of the entire cluster that will be carried by our technical teams. Want to discover more about that https://fosdem.org/2018/schedule/event/backup_ceph_at_scale/
