Ext4 users - remember to reduce reserved blocks!

By default ext4 reserves 5% of your disk for the root user. That made sense in 1999, but that’s insane now. You can run this command (as root) to reduce reserved blocks to around 4GB. On a 16TB ext4 file-system that will free up 795GB (since the default of 5% reserved = 800GB reserved for root!). tune2fs -r 1000000 /dev/<disk-device> This instantly frees up the space. You don’t need to unmount or remount or restart or anything. But first use “lsblk” and “df” commands to identify the ext4 f…

When you format a drive don’t forget to add -m 0 to remove reserve space.
sudo mkfs.ext4 -m 0 -T largefile4 /dev/sdX
