Hello @izzet

There are several reasons this can happen:

  1. Run du -s -h /* to see disk space maybe you have no space left because of incremental backups, website files, cache files froma multitude of wordpress/php websites, logs, a full /tmp folder

  2. Lack of essential resources such as server RAM or CPU. Does your server meet minum requirements or are there websites hogging resources, or trchnologies such as WAF, Firewalls, Scanners etc.

Actually my disk space was 30 GB after this error i increased to 60 GB but after that i did nothing. I don’t know if I need to restart the server

and also my 4 website already running with cyberpanel. Some days later i got this error. Its not fresh installing cyber panel

Run

du -s -h /*

Possible issues is cache folders are full or you are running wordpress backups on same device causing disk to be full

I am really sorry i dont know how can i run this code except this section. I dont use any other program to connect vm instance.

i am using wordpress fastest cache plugin . LScache is not active on my wordpress websites.

Seems you do not have access to your server. Contact GCP support for help

Yes depends where they are. Did you setup a local path for your cyberpanel websites backups ? If you did just change directory to that and delete everything in that folder
