What is this process and how can I reduce my server load?
JBD stand for 'journaling block device' (more information about it find here
) which its job is in between the block device and the file system.
so it is related to your ext4 file system using I/O and causing high loads. check if there's something running on your server or if there isn't anything active check the log files and see if they're populated with some interesting messages.
anyhow, when you say 'has high load than normal' what exactly the load is/was?
could you post the output of `top -n1 -b` when the load will be high
to reduce your server load, you first need to track-down the cause which is causing high loads and then optimize/fix it.
