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