There are similar questions, but nothing that was exactly on par with what I am inquiring. Completely fresh install of Centos 6, the server is setup with a BIOS RAID 1. I'm trying to set the number of inodes for the / partition during install. I've done this before with Debian, and on the partitioning screen there is an escape character you can use, to utilize mkfs, however I am unuaware of such for CentOS. Any help would be much appreciated!
After you've set up your partitions and the system creates them, you then come to the package selection screen. Here, you can press Ctrl+Alt+F2 to switch to a virtual console with a root shell. You can then reformat the partition to your liking. Press Ctrl+Alt+F6 to return to the installer when you finish.
