Which is the default percentage of reserved space for the root user on new ext4 filesystems?
The default percentage of reserved space for the root user on new ext4 filesystems is 5%. This reserved space is used to allow the root user to perform critical system operations even when the filesystem is nearly full, ensuring system stability and preventing system crashes.
By default, the ext3 and ext4 filesystems reserve 5% space for use by the root user. This reserved space counts as Non DFS Used . The Reserved block count is the number of ext3 / ext4 filesystem blocks that are reserved.
