Scheduled maintenance 2023-04-18 10:00 CEST: Ceph-CSI upgrade to v3.7 on zone LPG 2

[simu]

We will upgrade the ceph-csi driver on APPUiO Cloud cloudscale.ch LPG 2 to v3.7.2. This upgrade requires that workloads which mount RWX volumes with large amounts of files set spec.securityContext.fsGroupChangePolicy=OnRootMismatch to avoid long pod startup times.

If any your workloads already use spec.securityContext.seLinuxOptions.type=spc_t to fix long pod startup times, you should ensure that you also set spec.securityContext.fsGroupChangePolicy=OnRootMismatch on those workloads.

Please see https://docs.appuio.cloud/user/how-to/long-pod-startup.html for the latest recommended configurations to avoid or fix long pod startup times.

We completed the upgrade last Tuesday. If you notice that any of your workloads take unusually long to start, please verify that you've applied all the configurations documented in https://docs.appuio.cloud/user/how-to/long-pod-startup.html.
