Noticed an Unrecognized command

While running “top” from the terminal console I noticed an unrecognized command. Help me understand what “jbd2/sda2-8” and “jbd2/sda3-8” is describing. I suspect they are relating to partitions, but not sure. Thought I would post a question before referencing the book.

many thanks…

That’s some kernel thread, related to partitions/filesystems apparently.
Googling for “jbd2” came up with this:

So, you don’t think it is an intrusion of any kind? Just followed the link you sent and it helped me understand. Looks like it is not an intrusion, but rather a normal operation. Thanks for your help.

Many thanks…

No. You should have such a process for every mounted ext4 partition IIUIC.
