I'm running a VPS which has 10GiB.
Today, it was almost full. I noticed it when i was not able to update/upgrade.
ncdu command shows me that /dev/tty10 is taking 6.5 GiB.
How can i reduce it ? Can i delete it ?
ls -l | grep tty in /dev gives me that :

Remaking /dev/tty10 seems like the way to go: either you had none to begin with, and something decided to write to that (missing) device, or something removed the name from /dev.
If your VPS is using udev, rebooting might just fix that automatically (see for example notes in need to rebuild /dev).
