Node Mounting

Check Items

Check whether the default mount directory and soft link on the node have been manually mounted or modified.

• Non-shared disk
  • By default, /var/lib/docker, containerd, or /mnt/paas/kubernetes/kubelet is mounted to CCE nodes. Check whether /var, /var/lib, /mnt, /mnt/paas, and /mnt/paas/kubernetes have been manually mounted.
  • CCE creates the /var/lib/kubelet to /mnt/paas/kubernetes/kubelet link by default. Check whether the link has been manually modified.
• Shared disk
  • By default, /mnt/paas/ is mounted to CCE nodes. Check whether /mnt has been manually mounted.
  • CCE creates the /var/lib/kubelet to /mnt/paas/kubernetes/kubelet and /var/lib/docker or /var/lib/containerd to /mnt/paas/runtime soft links by default. Check whether the links have been manually modified.

Solution

How Do I Check Whether a Disk Is Shared?

1. Log in to the target node based on the check information.
2. Run the lsblk command to check whether vgpaas-share is mounted to /mnt/paas. If yes, a shared disk is used.

What Can I Do If an Error Occurred in a Node Mounting Check?

1. Cancel the manually modified mount point.
2. Cancel the modification on the default soft links.
