Wrong Disk space available

[giampiero7]

Hi, When adding a new image the popup shows that I have 0.1 GiB available, while in fact I have more than 20 GiB. How is the available space calculated? And where are the images stored in the filesystem?

Thanks!

And where are the images stored in the filesystem?

Somewhere under /var/lib/cmprovision/storage

You do are using the 64-bit edition of RPI OS? Any calculations done by PHP on large numbers will NOT work properly on 32-bit operating systems.

Hi, Yes, I'm using the 64-bit version. On the installation I was using, I had the path /var/log configured as tmpfs in /etc/fstab. To attempt to find the issue I started from a newly flashed image, long story short: if I remove the dir /var/log/nginx and reboot, cmprovision stops working as nginx.service fails to start:

$ systemctl status --no-pager -l nginx.service

It looks like it doesn't create the dir /var/log/nginx if it does not exist.

This might or might not be related to the original issue, which I didn't manage to reproduce.

Update: the original issue was due to /tmp being configured as tmpfs with limited space in /etc/fstab. So, with the following in /etc/fstab you create both issues in one go:

proc            /proc           proc    defaults          0       0
PARTUUID=aaaf927c-01  /boot           vfat    defaults          0       2
PARTUUID=aaaf927c-02  /               ext4    defaults,noatime  0       1
tmpfs           /tmp            tmpfs   noatime,size=64m      0       0
tmpfs           /var/log        tmpfs   noatime,size=16m      0       0
