What is kjournald

Sep 2, 0 United Kingdom. Hi What is kjournald? Regards, Garry. Jan 29, 0 For a number of years, Linux has been using a file system called. It's a nice reliable file system. However, if you've ever lost power on a linux box instead of using an orderly shutdown, you know that when you turn it on everybody has to wait for a long time while the ext2 filesystem checks out everything carefully.

That's a long, long time. Recently, a new version of the file system showed up, called cleverly enough. I suppose there was some improvement in it, I don't know, but the most unusual feature was that you could add 'journalling' to the ext3 filesystem.

Journalling means that the file system keeps a journal of what changes it's making, as it goes along. And if you should ever lose power, when you come back up, the filesystem can just go get the last journal, and this means it doesn't have to check and recreate everything from scratch.

The benefit to you is that it boots up quickly. There is also, I assume, more safety and accuracy when it's got a journal. The daemon which keeps the journal up to date is called kjournald. If you run 'top', you'll see kjournal is always running, and it pops up to the top regularly. Welcome to LinuxQuestions. You are currently viewing LQ as a guest.
