powerforum75 Posted November 21, 2023 Author Share Posted November 21, 2023 After a reboot I checked everything, it is due to a windows VM. How can I find out what the cause is? The VM has been there for some time! Quote Link to comment
JorgeB Posted November 21, 2023 Share Posted November 21, 2023 Kind of unusual, post the VM XML to see if there's anything we can see. Quote Link to comment

JorgeB Posted November 21, 2023 Share Posted November 21, 2023 Edited your post to add code tags, makes it more readable, I don't see anything out of the ordinary, and don't remember a VM filling up rootfs before, but maybe someone else can see something. Quote Link to comment
powerforum75 Posted November 21, 2023 Author Share Posted November 21, 2023 When I start the VM, rootfs goes up. But how can I see where it writes and what it writes? root@U-YK:~# df -hT /root/ Filesystem Type Size Used Avail Use% Mounted on rootfs rootfs 16G 4.9G 11G 32% / root@U-YK:~# ls -la total 20 drwx--x--- 3 root root 200 Nov 21 17:47 ./ drwxr-xr-x 21 root root 440 Nov 21 12:25 ../ -rw------- 1 root root 3705 Nov 21 17:47 .bash_history -rw-r--r-- 1 root root 316 Aug 31 19:57 .bash_profile -rwxr-xr-x 1 root root 60 Aug 31 19:57 .bashrc* drwxr-xr-x 3 root root 60 Aug 31 19:57 .config/ lrwxrwxrwx 1 root root 30 Aug 31 19:57 .docker -> /boot/config/plugins/dockerMan/ lrwxrwxrwx 1 root root 21 Aug 31 19:57 .ssh -> /boot/config/ssh/root/ -rw-r--r-- 1 root root 59 Nov 21 12:25 .tmux.conf -rw-r--r-- 1 root root 215 Nov 21 12:58 .wget-hsts root@U-YK:~# Quote Link to comment
Solution powerforum75 Posted November 22, 2023 Author Solution Share Posted November 22, 2023 I have found the error. 🤦♂️ It was the Urbackup client on the Windows VM that referred to one of my Unraid share directories in the file backup (I added it). But why it filled up the rootfs directory I don't know! 1 Quote Link to comment
