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 ;)
