Ext3 to ext2 or disable kjournald

There are two options for this:

1) Mount the filesystem as ext2, and/or use tune2fs to eradicate the journal:

2) Try setting the journaling mode to "writeback," which will only journal the filesystem metadata, not the actual data:

From a data integrity standpoint, both of these are probably bad ideas. However, if your goal is to write data a little bit faster without much regard for whether or not it will be corrupted after a crash, it might be worth a shot.

Just as topic says. How to convert ext3 to ext2 or just disable kjournald process.

I want to reduce Dick IO
I really, really wouldn't do this.

Ya, if you have to switch to ext2 to reduce disk IO you have bigger problems else where, find those, fix those. Journaling is a major part of any modern file system.

I see, so better is to keep ext3.

Thanks for suggestions
