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.
Procedure
-
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.
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
