Event Log

event log show -severity * -message-name callhome*

[netapp-cluster-01: mgwd: callhome.root.vol.recovery.reqd:EMERGENCY]: Call home for ROOT VOLUME NOT WORKING PROPERLY: RECOVERY REQUIRED.


  • Some Replicated Database (RDB) inconsistencies can be corrected automatically, in which case the message rdb.recovery.succeeded is emitted and no further action is required. If rdb.recovery.failed is logged, contact Support personnel for assistance, if required.


If the root volume is low on space, perform the following steps:

  1. Delete the old snapshot copies, delete unwanted files, and/or expand the root volume's capacity.
  2. After enough space is made available, reboot the controller.
    If required, contact Support personnel for assistance.
