Hi Cesar, Yes, we can look for the actual reason from the snapshot logs > applogfile > configurer folder (search with keyword "state"). i.e. 2023-06-20 08:25:25,842 Configurer[internalScheduler-11] INFO c.r.w.c.o.ClusterBackupOperationService - [Backup] requests all blade to take snapshot with time string [20230620082521] and set cluster state as Maintenance 2023-06-20 08:25:25,842 Configurer[internalScheduler-11] INFO c.r.w.c.d.s.ClusterStateMachine - Change cluster state from In_Service to Maintenance 2023-06-20 08:25:25,842 Configurer[internalScheduler-11] INFO c.r.w.c.d.s.ClusterStateMachine - It is the leader, update the shared info from blade [Ruckus-LAB-SmartZone100] changes : {ClusterState=Maintenance} 2023-06-20 08:25:25,843 Configurer[internalScheduler-11] INFO c.r.w.c.d.s.ClusterStateChangedHandler - Cluster state change : NewState [Maintenance] ========================================================================== 2023-06-20 08:25:35,659 Configurer[internalScheduler-11] INFO c.r.w.c.o.ClusterBackupOperationService - [Backup] all blade complete the snapshot, so set cluster state as In_Service 2023-06-20 08:25:35,659 Configurer[internalScheduler-11] INFO c.r.w.c.d.s.ClusterStateMachine - Change cluster state from Maintenance to In_Service 2023-06-20 08:25:35,660 Configurer[internalScheduler-11] INFO c.r.w.c.d.s.ClusterStateMachine - It is the leader, update the shared info from blade [Ruckus-LAB-SmartZone100] changes : {ClusterState=In_Service} 2023-06-20 08:25:35,660 Configurer[internalScheduler-11] INFO c.r.w.c.d.s.ClusterStateChangedHandler - Cluster state change : NewState [In_Service] Regards Saurabh

And among these possibilities, can I know the specific reason? As I said, I looked at several logs and found nothing. If I can find the right item you mentioned, which log would I have to see?

Hi Cesar,Usually system will go to maintenance mode due below two reasons.1- While creating a cluster backup2- Creating a configuration backupPlease note that it is not limited to just above two reasons, as system may also enter into maintenance mode while a firmware upgrade, service down/restart etc.Regards,Syamantak Omer
