CSI driver: csi_sock: bind: address already in use
This issue was recently brought to my attention...
The Container Storage Interface (CSI) Driver container may not start with the below error in the container log.:
time="2019-10-25T16:10:07Z" level=fatal msg="failed to listen" error="listen unix
/var/lib/kubelet/plugins/vxflexos.emc.dell.com/csi_sock: bind: address already in use"
Workaround:
There are currently 2 workarounds.
Requires reboot
1. Remove the file under /var/lib/kublet/plugins/vxflexos.emc.dell.com/csi_sock
2. Reboot the node.
Does not require reboot
1. Uninstall the CSI Driver for VxFlex OS
2. Removing the file under /var/lib/kublet/plugins/vxflexos.emc.dell.com/csi_sock
3. Reinstall the driver
i.e. no node reboot is necessary.
Resolution:
CSI Engineering is currently addressing this problem, but has not provided a fix in a released patch.
