Hey!! Linux ass hat here, Dont really know what to do with this. Hoping some wizard will come to my rescue
Do I need to delete some file, becourse there is plenty of disk space on the VPS so I dont get this message when I try to start my node


No space left on device means your disk is full. Delete something that you don't need any more or buy a larger disk.
hmm alright, Was there not some huge file in Dash that is ok to delete
Already tried to delete ~/.dash/debug.log?
I recommend to set a cronjob to delete it once a day, this debug file is getting filled very fast (about 60MB/day?)
sudo crontab -e
choose 2 and add
0 0 * * * > ~/.dash/debug.log
save
Thanks, did do this and rm debug.log but I still get the same message

Find files that are more than 100M :
find / -size +100M
Find top 10 bigger directory :
cd /
du -Sh | sort -rh | head -n 10
In case you have more than one FileSystem check FileSystem filling rate:
df -h
