[PVE-User] Container exceed disk size

[Bertorello, Marco]

Dear PVE user,

I setup a container with 8GB disk:

arch: amd64
cores: 1
hostname: adguard
memory: 1024
net0: 
name=eth0,bridge=vmbr0,gw=192.168.1.1,hwaddr=E6:07:A3:9E:86:FB,ip=192.168.1.201/24,type=veth
onboot: 1
ostype: ubuntu
rootfs: DS1:subvol-119-disk-0,size=8G
swap: 512

but, inside the container, if I run a df -h command, i get:

root at adguard:~# df -h
Filesystem             Size  Used Avail Use% Mounted on
zp1/subvol-119-disk-0  3.0T   15G  3.0T   1% /
none                   492K  4.0K  488K   1% /dev
tmpfs                   16G     0   16G   0% /dev/shm
tmpfs                  6.3G   92K  6.3G   1% /run
tmpfs                  5.0M     0  5.0M   0% /run/lock
tmpfs                  3.2G     0  3.2G   0% /run/user/0

as you can see, the guest OS see the full data storage size (ZFS) and 
exceed the 8GB size I configured.

checking another container on the same host, it works as expected:

arch: amd64
cores: 1
hostname: secret
memory: 512
net0: 
name=eth0,bridge=vmbr0,gw=192.168.2.1,hwaddr=76:3F:CA:A7:0C:3F,ip=192.168.2.253/24,type=veth
net1: 
name=eth1,bridge=vmbr0,hwaddr=7E:FA:30:2B:E5:ED,ip=192.168.1.99/24,type=veth
onboot: 1
ostype: ubuntu
rootfs: DS1:subvol-116-disk-0,size=8G
swap: 512

root at secret:~# df -h
Filesystem             Size  Used Avail Use% Mounted on
zp1/subvol-116-disk-0  8.0G  2.0G  6.1G  25% /
none                   492K  4.0K  488K   1% /dev
tmpfs                   16G     0   16G   0% /dev/shm
tmpfs                  3.2G  112K  3.2G   1% /run
tmpfs                  5.0M     0  5.0M   0% /run/lock
tmpfs                  3.2G     0  3.2G   0% /run/user/0

them are in the same data storage.

If can be usefull, I'm running PVE 7.0-13, with 5.11.22-5 kernel.

Any idea, why and how I can solve?

Thanks a lot and best regards,
