PUMP not working?

[i5o]

Hello. I'm trying to get to use pimod, but my first test already failed :)
Here is my Pifile

FROM image/2018-11-13-raspbian-stretch.img

PUMP 1500

RUN bash -c 'echo "${CHROOT_MOUNT}"'

and here is the output I get, is this normal? I tried running as non-sudo user:

ignacio@cat:~/pimod$ ./pimod.sh treehouses.Pifile

then with sudo

also docker

ignacio@cat:~/pimod

Just wondering if this is normal or to check if I'm doing something wrong

thank you

Thanks for trying pimod and please excuse the troubles.

Based on your first and the following logs, the problem lies with the execution of pimod's chroot part as an unprivileged user. However, it seems like a loop device was created, which is now causing problems.

An easy fix would be:

# check if there are any loop devices
losetup -a

# delete all orphaned loop devices (replace loop0 with your devices)
sudo losetup -d /dev/loop0

# just clean up
sudo dmsetup remove_all

# Check again and, if anything is present, try deleting them again.
# If everything fails, reboot your machine ¯\_(ツ)_/¯

Afterwards, running your Pifile as a privileged user (like root or inside Docker) should work.

Please consider, the CHROOT_MOUNT variable is used inside the pimod.sh script, but should not be passed inside the chroot. Therefore your echo - executed inside the chroot - will be empty.

So I just started a clean session (rebooted my system and started from scratch) and here is my whole output, not sure if this error is relevant

am I doing something wrong about it?

Could you please try to execute pima.sh as root using sudo?

As you see, problems start to occur, when you /dev/mapper/control can't be opened:

ignacio@cat:~/pimod$ ./pimod.sh treehouses.Pifile
