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.
- Display the node’s core dump files and their names by using the system node coredump show command.
- Delete unwanted core dump files from the node by using the system node coredump delete command.
- Access the nodeshell: system node run -node nodename
nodename is the name of the node whose root volume space you want to free up.
- Switch to the nodeshell advanced privilege level from the nodeshell: priv set advanced
- Display and delete the node’s packet trace files through the nodeshell:
- Display all files in the node’s root volume: ls /etc/
- If any packet trace files (*.trc) are in the node’s root volume, delete them individually: rm/etc/log/packet_traces/file_name.trc
- Identify and delete the node’s root volume Snapshot copies through the nodeshell:
- Identify the root volume name: 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
- Display root volume Snapshot copies: snap list root_vol_name
- Delete unwanted root volume Snapshot copies: snap delete root_vol_name snapshot_name
- Exit the nodeshell and return to the clustershell: exit
