[SOLVED] Mounting iso-file from ZFS hangs system

Mounting an iso-file from a ZFS (zfs-git 0.6.4.2_r0_g44b5ec8_4.1.6_1-1 (archzfs-git)) zpool completely freezes my system (4.1.6-1-ARCH).

When mounting a iso-file from a mounted ZFS pool the system hangs indefinitely (at least 10 minutes).
When mounting the same iso-file from a mounted ext4 partition, it's mounted immediately.

The ZFS pool is a raidz1 with 4 devices.
The ext4 partition is a logical volume made with LVM on mdraid 5 with 5 devices.

For testing purposes I have created a raidz1 zpool alongside my other partitions. This is the first, rather impressive problem I have run into.

The only additional info I was able to generate is with the command " sudo mount filename.iso /media/iso -t udf -o loop ". It first generated a line stating that the loop device was mounted read-only, before freezing.

Does someone know where I could look for information to tackle this problem?

I don't know how often demizer reads this forum, so I suggest you add a comment to the zfs-git AUR page and/or post an issue to his archzfs on GitHub (http://github.com/demizer/archzfs) referencing your zfsonlinux issue. From the reply to your zfsonlinux issue it seems 0.6.4 is broken.

It's working with the git-version. How do I tag this thread as SOLVED?
