What the DRX should be configured for is the configuration of individual replication resources and the global settings configuration that the DRX requires to run. Settings for the individual resources are configured through the drbd.conf file and the global settings are configured through the drx.conf file.

4.3. drx.conf
You can set the DRX internal properties independently of the DRBD configuration. Normally, you don't need to provide a property file because it works with the DRX preferences. This property is applied at the start of the DRX, and the DRX property file is created with reference to the following properties table.
- file name: "drx.conf"
- default path: DRX Installed path
- Caution: [global] section should be described at the beginning of the file
...
- Located in "base-dir/lang" of the configuration.
- ex) korean.ini
...
DRX install path
...
Default path where DRX is installed
...
Windows:
Linux:
...
Timeout value in seconds used by socket connect or listen actions
...
Timeout value in seconds after connecting to a remote DRX, while sending and receiving initialization packets
...
on: Allow only the IP connections set in dbd.conf.
off: Allow connections for all IPs.
...
Block size to be used for compression/encryption
- Note: The size of the transfer buffer for compression/encryption is set to twice the block-size value and is set to 1MB maximum.
...
Number of threads to use when processing multi-thread packets.
※ It is intended for tuning and debugging, so it is not recommended to make any changes.
