LXC, size difference between disk and inside container

[stoddart004]

Hello,

when I create a LXC container with a 5GB disk, I have inside the container 4.84 GB (4.839508056640625).

There is always a (smaller) difference between the requested disk size and the root size of the container.

I think i miss something oblivious, if someone has an idea ?

For my project i need to have 5GB (really) inside the container.






Inside the container (with df -h):
Filesystem Size Used Avail Use% Mounted on /dev/mapper/pve-vm--118--disk--0 4.9G 2.7G 1.9G 59% / none 492K 4.0K 488K 1% /dev udev 32G 0 32G 0% /dev/tty tmpfs 32G 0 32G 0% /dev/shm tmpfs 13G 196K 13G 1% /run tmpfs 5.0M 0 5.0M 0% /run/lock


Thank you.

Also keep the difference between "GiB" and "GB" in mind. 5 GB = 4.6566 GiB. And "G" can stand for "GiB" or "GB", depedning on the software you use to display a capacity. PVE is reporting you got 4.84 GiB not GB. So that is actually more than 5 GB.
If you for example want df to show GB instead of GiB you will have to use the "-k" option or otherwise it will show GiB: df -k
