cannot create '<pool>/<volume>': no such parent '<pool>'

[thehaven]

zfs list shows me that the pool exists, when I try and create an additional volume on the pool I get the message:

cannot create '<pool>/<volume>': no such parent '<pool>'

Not sure if this is related to: #46 or not but here are the details.

I have the latest zfs/spl from git both in userland tools and compiled into the kernel.
SPL: commit 4c99541
ZFS: commit 01b738f

I was previously using 0.6.2 but just upgraded to master.

Here's a run down of commands showing the existing volumes as well as what happens when I try and create a new volume:

Any help appreciated, please let me know if you need additional info.

Although your ``ldd` output looks OK at first glance, this exact error is what you expect to get when the userland and kernel modules are mismatched or you've got stale shared libraries laying around.

Since you've apparently compiled the code yourself, go into the build directory and try running cmd/zfs/zfs create <pool>/<fs>. If that fails, your kernel module is out of sync. If it works, your installed programs and libraries are out of sync.

Looks like for some reason when I run make install for the userland utilieis its not copying the updated zfs binary into place. Manually copying it fixed the issue. I'll close this for now as its likely something I've missed in the build process.

Thanks for the helpful feedback.

@thehaven Remember the default --prefix for configure is /usr/local, make sure you run ./configure --prefix=/usr if your just doing a 'make install' on your system and not using the packages.
