various roles
edit
1 Management server: responsible for
the
management of each data storage server, file read and write scheduling, file space recovery and recovery. Multi-node copy
2
Metadata
log server: responsible for backing up changes to the master server
The log file, the file type is changelog_ml.*.mfs, so that it can take over the work of the master server when there is a problem
3
Data storage
server: responsible for connecting to the management server, obeying the scheduling of the management server, providing storage space, and providing data transmission for customers.
4 Client: Connect the data storage server managed by the remote management server through the fuse
kernel interface. It seems that the shared file system and the local unix file system use the same effect.
