Hi all,
bcachefs fails to mount loop device on kernel on both 6.7 and 6.8.0-rc1.
Is mounting loop even supported?
dd if=/dev/zero of=test_file bs=400M count=1
losetup /dev/loop0 test_file
mkfs.bcachefs /dev/loop0
mount -t bcachefs -o loop test_file /mnt
=> Unknown command /dev/loop0
modprobe bcachefs
mount -t bcachefs -o loop test_file /mnt
=> mount: /mnt: failed to setup loop device for test_file.
mount -t bcachefs test_file /mnt
=> Unknown command test_file
mount -t bcachefs -o loop /dev/loop0 /mnt
=> Unknown command /dev/loop1
mount -t bcachefs /dev/loop0 /mnt
=> Unknown command /dev/loop0
bcachefs mount /dev/loop0 /mnt
=> Unknown command mount
Thanks for info.
Kind regards,
Petr

What version of the bcachefs CLI tool are you using? Is it distribution
provided or did you build it yourself?
The mount command has been implemented in Rust for a while (since
28f703cc256f "Rust now integrated into bcachefs binary") and if building
without Rust support (BCACHEFS_NO_RUST defined), that command won't be
included in the binary.
In more recent versions of bcachefs-tools, building without Rust is not
supported at all.
I don't think this has anything to do with loop devices specifically.

Official openSUSE Tumbleweed package:
$ rpm -qf $(which bcachefs)
bcachefs-tools-1.4.0-1.1.x86_64
BTW this was found with LTP, which has 2 APIs: C API, which uses mount(2)
which works well and shell API which uses mount (which uses bcachefs) and here
it fails.
Kind regards,
Petr

Sounds like Suse isn't building with our Rust code - but, that's about
to become mandatory...

Indeed NO_RUST=1. Thank you both for a quick info!
