Hi,
I compiled ext4mount from git, and tried to mount an ext volume. Probably ext3.

# ls /tmp/mnt /private/tmp/mnt
ls: /private/tmp/mnt: Input/output error
ls: /tmp/mnt: Input/output error

Any ideas on how I could troubleshooting this?

Same issue here on Sequoia (15.1.1 (24B91))

The image I am using can be fetched from https://downloads.raspberrypi.org/raspbian/images/raspbian-2017-04-10/2017-04-10-raspbian-jessie.zip

VM_LOC=~/qemu
IMAGE=$VM_LOC/2017-04-10-raspbian-jessie.img
MNT=$VM_LOC/raspbian
INFO=$(hdiutil attach $IMAGE)
DEV=$(echo "$INFO" | awk '/Linux/ {print $1}')

$ sudo file -s $DEV
/dev/disk2s2: Linux rev 1.0 ext4 filesystem data, UUID=b105f9a8-f450-4976-8ac8-69053f57bab4 (extents) (large files)

$ sudo -s ext4fuse $DEV $MNT -o allow_other
$ echo $?
0

$ sudo ls -al $MNT

ls: /.../raspbian: Input/output error

ll $MNT
"/.../raspbian": Input/output error (os error 5)
