TitleWM Cluster: Altitude AP loading factory defaults after a reboot
Symptoms

  • AP reporting high flash consumption: %DIAG-4-FREE_FLASH_DISK: Free flash: file system space, 1.4% is less than limit 90.0%
Environment
  • Altitude Access Points
  • Summit WM3000 Series Controllers
  • WiNG 5.X
  • Cluster
Cause
The Active and Standby cluster nodes may be out of sync due to some previous fault in the network.
Resolution
Check cluster status for out of sync condition by issuing the "show cluster members" command:
L3L_K2_U41_​WM1#show cluster members 
-----------------------------------------------------------------------------------------------
     HOSTNAME       MEMBER-ID           MAC          MASTER OPERATIONAL-STATE    LAST-SEEN     
-----------------------------------------------------------------------------------------------
  L3L_K2_U40_WM2   46.42.21.A6   00-04-96-42-21-A6   False   active            00:01:01 ago    
  L3L_K2_U41_WM1   46.42.21.4E   00-04-96-42-21-4E   True    standby           self            
-----------------------------------------------------------------------------------------------

Here the standby node is acting as master.  

Reboot the standby controller to force a failover to the active controller.
