Hello,
i have i single server with one LXC container.
This istance, display a strange output using df

root@p: ~ $ df

If i add for example 300G to my vps, still remain at 170G free...

hi.

how do you do that exactly? how do you mount the new disk (or do you repartition?)? did you make a filesystem on it?

No partition o FS, it's a simple VPS LXC, and the host is ZFS.

but how do you add it to your container? through gui?
can we see a config file maybe? (`pct config CTID`)

again, how do you add the 300G space to your container?

if you just edited the size on the config file, then it won't work.

you can use the gui:

you need to either add a new disk

container -> resources -> add -> mount point

or resize the current one.

container -> resources -> root disk -> resize disk

I have used GUI.
Now, deleting sole snapshot i can see the 300G added .. so i think all the space is used by snapshots..

i'm glad the problem is gone. you can mark this thread [SOLVED] so others knows what to expect
