Managing the Operation Mode
The FluidFS cluster has three operation modes:
• Normal: System is serving clients using SMB and NFS protocols and operating in mirroring mode.
• Write-Through Mode: System is serving clients using SMB and NFS protocols, but is forced to operate in journaling mode. This
mode of operation might have an impact on write performance, so it is recommended when, for example, you have repeated
electric power failures.
• No Service: System is not serving clients using SMB or NFS protocols and allows limited management capabilities. This mode
must be selected before replacing a NAS appliance.
