Context

SFS Turbo can provide multiple service nodes for shared log output directories, facilitating log collection and management of distributed applications. Features of such services are as follows:

A shared file system is mounted to multiple service hosts and logs are printed concurrently.
Large file size and small I/O: The size of a single log file is large, but the I/O of each log writing is small.
Write I/O intensive: Write I/O of small blocks is the major service.

Configuration Process

Log in to the SFS console. Create an SFS Turbo file system to store the log files.
Log in to the server that functions as the compute node and mount the file system.
Configure the log directory to the shared file system. It is recommended that each host use different log files.
Start applications.
