On my proxmox node running PVE 5.1-4, /dev/mapper/pve-root is 100% full. How to sort out this issue ?

Eine Uptime von über zwei Jahren zeugt von vernachlässigter Wartung und Pflege. Scnr.

Kandidaten zum Löschen findet man oft in /var/log. Ich taste mich meist schrittweise 'runter und fange mit cd /; du -k -s * | sort -n oder auch apt clean an.

Viel Erfolg

Edit: usually I write English in the German forum...

You need to delete some files to free up space. Look into /var/log and delete (very) old files. If you delete the current log files you need to restart rsyslog to make the running daemon let go the currently open file. Run cd /; du -k -s * | sort -n to find the largest folders. "cd" into them and repeat the "du"-command. The apt cache can be cleared by apt clean without any loss of installed packages.
