Starting the Smart Prefetch Engine
Ensure that the file system format of the bcache drive is ext4. Other file system formats are not supported.
Run the lsblk -fs command to check whether the file system format of the bcache drive is ext4.
- Start the acache_client service.
sudo systemctl start acache_client
- Check whether the acache_client has been started successfully.
sudo systemctl status acache_client
If the command output contains active (running), the acache_client has been started successfully.
When the acache_client service is being started, if an error message is displayed stating "Warning: acache_client.service changed on disk. Run 'systemctl daemon-reload' to reload units.", resolve this problem by performing the following operations:
- Reload the service configuration file.
systemctl daemon-reload
- Start the acache_client service.
systemctl start acache_client
