Hi,
I use the below script reproduce the error.
mkdir -p /media/xfs
mkdir -p /media/scratch
dev0=$(losetup --find)
dd if=/dev/zero of=1.tar bs=1G count=1
dd if=/dev/zero of=2.tar bs=1G count=1
losetup $dev0 1.tar
dev1=$(losetup --find)
losetup $dev1 2.tar
mkfs.xfs -f $dev0
mkfs.xfs -f $dev1
mount $dev0 /media/xfs
mount $dev1 /media/scratch
export TEST_DEV="$(mount | grep '/media/xfs' | awk '{ print $1 }')"
export TEST_DIR="/media/xfs"
export SCRATCH_DEV="$(mount | grep '/media/scratch' | awk '{
print $1 }')"
export SCRATCH_MNT="/media/scratch"
git clone git://git.kernel.org/pub/scm/fs/xfs/xfstests-dev.git
cd xfstests-dev
make
for i in $(seq 20);do
./check generic/461
done
