Jail mount points and storage size

[SilviaS152002]

I am currently running TrueNAS 12.0 U2. I have a jail with BTFS running on a SSD-only pool (VM) with about 240 GB, and I have a main storage space in another pool (Chia) with about 6TB of space. I made a mount point like so:
Source: /mnt/Chia/Chia/BTFS Destination: /mnt/VM/iocage/jails/BTFS/root/btfs-files

However, when I was trying to allow BTFS to use up to 5TB of space, it tells me there is only maximum of 240GB.
Running df -h gives me this output:

Code:

root@BTFS:~ #  df -h
Filesystem                   Size    Used   Avail Capacity  Mounted on
VM/iocage/jails/BTFS/root    247G    702M   247G      0%    /

I have a few questions:

• Why is the size still 247G even if I mounted a 6TB to it?
• How do I allow the software to recognize the size of the mount drive?

Sorry if my questions seem rather odd or weird, I am relatively new to CLI and Linux\Unix\FreeBSD.

Well, root "/" is on the SSD, so that's right.

You will find that you can probably store more than that under /btfs-files in the jail.

You will find that you can probably store more than that under /btfs-files in the jail.

I understand this part, but the software only reads the SSD's size and not the mounted pool's space, even if I point it to /btfs-files.
Or should I try mount it to VM/iocage/jails/BTFS/root/btfs-files for it to recognize the extra space?
