disk space lost in mke2fs


What percentage of disk space is lost when we create ext3 filesystem with "mke2fs -j" for making journal and superuser space etc.
I need to automate the filesystem creation process for every new server for installing database which has specific size reqirements for all the partitions. So to be on safe side , i need to add that lost percentage of disk space while creating the RAID.

See the man page for mke2fs. For the -J option, you can specify the filespace to allocate for the journal (minimum 1024 blocks), See also -m (space reserved for the super-user defaults to 5%, but can be changed).

Note: that's -J (uppercase) as opposed to -j (lowercase).

Thanks for your help.
Ok but if we don't specify anything , in that case 5% would be taken up for super-user and what is the default % taken up for journal?
