At present we have single log level configuration for all the containers running for our CSI pods, which has been defaulted to log Level 5. However this cause many logs to be spitted in a cluster and cause log spamming to an extent. This commit introduce one more log level control for CSI pods called sidecarLogLevel which defaults to log Level 1. The sidecar controllers like snapshotter, resizer, attacher..etc has been configured with this new log level and driver pods are with old configruation value. This allow us to have different configuration options for sidecar constrollers and driver pods. With this, we will also have a choice of different configuation setting instead of locking onto one variable for the containers deployed via CSI driver. To summarize the CSI containers maintained by Ceph CSI driver has log level 5 and controllers/sidecars not maintained by Ceph CSI driver has log level 1 configuration.

ceph-csi-cephfs
The ceph-csi-cephfs chart adds cephFS volume support to your cluster.
Install from release repo
Add chart repository to install helm charts from it
helm repo add ceph-csi https://ceph.github.io/csi-charts
Install from local Chart
we need to enter into the directory where all charts are present
cd charts
Note: charts directory is present in root of the ceph-csi project
Install Chart
To install the Chart into your Kubernetes cluster
-
For helm 2.x
helm install --namespace "ceph-csi-cephfs" --name "ceph-csi-cephfs" ceph-csi/ceph-csi-cephfs -
For helm 3.x
Create the namespace where Helm should install the components with
kubectl create namespace ceph-csi-cephfsRun the installation
helm install --namespace "ceph-csi-cephfs" "ceph-csi-cephfs" ceph-csi/ceph-csi-cephfs
After installation succeeds, you can get a status of Chart
helm status "ceph-csi-cephfs"
Delete Chart
If you want to delete your Chart, use this command
-
For helm 2.x
helm delete --purge "ceph-csi-cephfs" -
For helm 3.x
helm uninstall "ceph-csi-cephfs" --namespace "ceph-csi-cephfs"
If you want to delete the namespace, use this command
kubectl delete namespace ceph-csi-cephfs
