Default size of journal?
Good afternoon!
I'm sorry if this is a repeat, but I was wondering what the default journal size is for ext4 when it's built on a single partition? Or does it vary in size as needed?
TIA!

It varies with the size of the filesystem. I believe the largest default size is 128MB, but I don't know offhand what the cutoff size is.
Cheers, Andreas

Is there a simple formula for how the journal size varies with the file system size? Perhaps linear?
Thanks!

Disregard - Eric answered it for me (didn't finish all my email before responding). Apologies.
