Can the EXT reserved block allocation be reduced on larger filesystems?
Issue
- The ext2, ext3, and ext4 filesystems reserve 5% of free blocks for use only by root. For large filesystems, this can be a significant amount of unavailable space. Can this be reduced?
Environment
- Red Hat Enterprise Linux 5, 6 and 7.
- EXT 2, 3 and 4.
