Comment 2 for bug 1859827

Test Environment:
---

Eoan/Focal amd64 kernel on i386 dpkg arch.

$ dpkg-architecture | grep DEB_HOST_ARCH=
DEB_HOST_ARCH=i386

$ uname -m
x86_64

Test Steps:
---

apt install -y gfs2-utils corosync dlm-controld linux-modules-extra-$(uname -r)

corosync-quorumtool -e 1
systemctl restart dlm.service

DISK=disk.img
dd if=/dev/zero of=$DISK bs=1M count=128 2>&1
LOOP=$(losetup --find --show $DISK)

mkfs.gfs2 -p lock_dlm -t debian:test -J 32 -j 2 -O $LOOP
mount $LOOP /mnt

gfs2_jadd -j 1 /mnt

Note:
The 'gfs2_jadd' command either fails with ENOTTY upfront or goes on.
For a simple test let's make it fail with ENOSPC instead.
