  • ONTAP 

Description

  • 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
  • Note: When a node's root volume reaches 100% full, the system will panic, frequently requiring root volume recovery.
  • Example:

PANIC: Process vifmgr unresponsive for 180 seconds in process nodewatchdog on release 9.7P6 (C) on Sat Nov 23 09:42:39 UTC 2024

  • EMS logs  will denote that root volume vol0 is full:                                                                                                                                                                                                                               monitor.full.alert]:  Volume "vol0" is full (using or reserving 100%% and 3%% of inodes                                  wafl.vol.full:alert]: Insufficient space on volume vol0 to perform operation                               
  • The error may also be seen when accessing the node's Service Processor:

CRITICAL. This node is not healthy because the root volume is low on space (<10MB). The node can still serve data, but it cannot participate in cluster operations until this situation is rectified. Free space using the nodeshell or contact technical support for assistance.
