Freeing up space on a node’s root volume

A warning message appears when a node's root volume has become full or almost full. The node cannot operate properly when its root volume is full. You can free up space on a node's root volume by deleting core dump files, packet trace files, and root volume Snapshot copies.

Steps

  1. Display the node’s core dump files and their names by using the system node coredump show command.
  2. Delete unwanted core dump files from the node by using the system node coredump delete command.
  3. Access the nodeshell by entering the following command: system node run -node nodename
    nodename is the name of the node whose root volume space you want to free up.
  4. Switch to the nodeshell advanced privilege level by entering the following command in the nodeshell: priv set advanced
  5. Display and delete the node’s packet trace files through the nodeshell:
    1. Display all files in the node’s root volume by entering the following command: ls /etc/
    2. If any packet trace files (*.trc) are in the node’s root volume, delete them individually by entering the following command: rm /etc/file_name.trc
  6. Identify and delete the node’s root volume Snapshot copies through the nodeshell:
    1. Identify the root volume name by entering the following command: vol status
      The root volume is indicated by the word "root" in the "Options" column of the vol status command output.
      Example
      In the following example, the root volume is vol0.
      node1*> vol status
      
               Volume State           Status            Options
                 vol0 online          raid_dp, flex     root, nvfail=on
                                      64-bit
      
    2. Display root volume Snapshot copies by entering the following command: snap list root_vol_name
    3. Delete unwanted root volume Snapshot copies by entering the following command: snap delete root_vol_name snapshot_name
  7. Exit the nodeshell and return to the clustershell by entering the following command: exit
