Debian 11 - Increase /dev/loop devices

By default the quantity of /dev/loop devices is 8, 0-7.

Snap eats all 8, if you want more you need to increase it. But how to do it?

In the suggestions replace <quantity> with the number of loop devices that are needed.


Failed suggestion - Edit grub command line

Open /etc/default/grub, and add max_loop=<quantity> to GRUB_CMD_LINUX or GRUB_CMD_LINUX_DEFAULT, like this:

GRUB_CMDLINE_LINUX="max_loop=10"

Then:

update-grub
update-initramfs -c -k all

This did not work.


Failed suggestion - Add a line in /etc/modules

Open /etc/modules, add:

loop max_loop=<quantity>

Then maybe:
update-grub
update-initramfs -c -k all

This did not work.


Working suggestion - Add a line in /etc/modprobe.d/loop.conf

Create /etc/modprobe.d/loop.conf

Add this line:
options loop max_loop=<quantity>

Then maybe:
update-grub
update-initramfs -c -k all

Source: https://linuxdock.com/increase-the-loop-device-count/

This worked.
