SmartZone "Crash mode" ??

miroslav_vukovi — Fri, 20 Sep 2019 12:12:39 GMT

Hi,
today we experienced insufficient disk space situation on our VMWare host where the SmartZone was installed. We moved that VM to another datastore and started VM with no problem. SmartZone is accessible via ssh but all services are down:

show service
% All services are down

If I try to start services I got this message:

Starting all services...
Process had been started before and running...
System is in crash mode, please contact system administrator...
Successful operation

CRASH mode ? How to switch back to regular mode?
I can't find any information about crash mode.
Does anyone have experience with this situation?

Thanks

Hello vmiro,

I think the best advice I can give would be to log a case with Ruckus Support, as there are likely a number of steps required, including manually forcing the system out of crash mode which requires elevated access to the SZ shell.

Hi Vmiro,

Crash mode indicates a major error occurred in the vSZ data base system, and the system goes into this mode to prevent further damage to the data base.

Unfortunately rebooting the node will not clear Crash Mode, you need to open a ticket with Ruckus Support who need to access your system remotely and enter into the operating system to clear the crash mode and also check for errors in the logs indicating what issues may have occurred. This can only be done by Ruckus support.

Crash mode is verified by running the SZ command: show cluster-state

N1# show cluster-state
Current Management Service Status : Out of service
Current Node Status : Out of service
Cluster Status : Out of service
Cluster Operation : None
System Mode : Crash

Cluster Node Information
----------------------------------------------------------------
No. Name Role
----- ------------------------ -----------
1 N1-C LEADER

The only way for a user to clear this state is to factory default the system and rebuild the configuration.

The quickest and cleanest way to fix the problem is to have the state manually fixed by Ruckus Support who can also check the logs and then allow services to be restarted.

Sorry for the problems this has caused.

Hi @vmiro
How about your issue?
Unfortunately, I got the same issue. Now I am waiting the Ruckus Support.

I didn't have luck.
The technician from the support set the vSZ easily to Normal mode. But none of the services were able to start. We tried to manually start services but with no success. After some time vSZ was gone to Crash mode again. They tried several time switching to Normal mode and to start even one service, but...nothing.
I created a new instance and restore a backup of the cluster, created earlier. Now, I'm waiting for the support to deal with the licenses, because the serial number of the vSZ has changed.

I wasn't able to run a backup on the old vSZ because it needed some service to be up 😞
So, if you don't have a backup of the cluster you'll need to configure vSZ from the scratch.
