Hi everyone,

I did a couple of research about journal's size on the Internet but I
didn't find any good results.

How do you calculate the 'ideal/required' size of an OSD journal? I
suppose that the calculation is based on the disk size, but...

Thank you in advance.

Cheers!

Ok thanks!

Seems logic, just need to test that.

Thanks ;)
