Maintenance Ceph storage cluster

Maintenance Ceph storage cluster

24-02-2021 00:00:00 - 24-02-2021 07:00:00

Urgency: Planned
Affected services:
- Virtual machines
- Shared storage
- Shared hosting
- MSSQL instances
- POP/IMAP mail servers
Expected impact:
- Reduced redundancy
- Shared filesystem (CephFS) unavailable shortly (possibly multiple times)
Customer intervention required: No
Reference number: 172471

Summary:
 
The Ceph storage cluster will receive software updates.
 
 
Details:
 
The Ceph storage cluster will receive software updates. We do not expect noticeable impact on the functioning of the cluster during this maintenance, with the exception of the shared filesystem service (CephFS). CephFS will be unavailable for a short period of time, possibly multiple times. The cluster will be updated node by node. When updating the nodes we will wait for a fully healthy status of the cluster (Ceph HEALTH_OK), before starting the upgrade of the next node. The cluster has been designed to be updated while being in use (live updating). However, every update comes with (extra) risks, therefore the update process will take place during a maintenance window.
