[Backport v2.6] GlusterFS kubelet image issue #40542

Closed rancherbot closed 1 year ago

rancherbot commented 1 year ago

This is a backport issue for https://github.com/rancher/rancher/issues/40508, automatically created via rancherbot by @snasovich

Original issue description:

Issue description: To make glusterfs work properly, we have a workaround in https://docs.ranchermanager.rancher.io/how-to-guides/advanced-user-guides/manage-clusters/create-kubernetes-persistent-storage/manage-persistent-storage/about-glusterfs-volumes

But it appears to be giving an error as required libraries missing inside the hyperkube image

Business impact: Medium

Troubleshooting steps: Mount the system-run binary to hyperkube image and execute the following command

/usr/bin/systemd-run --version

Repro steps:

Run the following command in any RKE cluster node

Workaround: Is workararound available and implemented? yes What is the workaround: Adding a volume with specific library works and it can be configured directly on kubelet by using extra_binds

-v /lib/systemd/libsystemd-shared-249.so:/lib/systemd/libsystemd-shared-249.so

Actual behavior: systemd-run --version display the following error

/usr/bin/systemd-run: error while loading shared libraries: libsystemd-shared-249.so: cannot open shared object file: No such file or directory

Expected behavior: systemd-run --version should be executed correctly and list the following result

systemd 249 (249.11-0ubuntu3)
