Receives a request from the sfcfsd or the commands and provides the communication paths of commands-sfcfsd, commands-sfcprmd and inter-node. Configuration database management and the management partition I/O functions are also provided.
Used to monitor the startup, stop, or failure of the processes that shares the GFS Shared File System. When the configuration process starts or executes another daemon or command, a request is transmitted to sfcprmd, and then sfcprmd executes a daemon or a command as required.
The process from which a request is transmitted is referred to as the client process, while the process to be started from sfcprmd as required is referred to as the target process.
The target process is monitored by sfcprmd and, when the process terminates normally or abnormally, the status is posted to the client process.
Provides MDS/AC control functions such as the GFS Shared File System operation start/stop, failover of MDS.
Used to provide functions such as node down event reception, domain-wide lock, membership information acquisition, and node state acquisition.
Performs live monitoring of sfcprmd that is to be monitored. When the process to be monitored abnormally ends (process down), this daemon makes system go down in order to maintain consistency of file systems.
