What steps will reproduce the problem? 1. zfs create -V 10m pool/zvol01

What is the expected output? What do you see instead? internal error: Unknown error: 8192 Abort trap

What version of the product are you using? On what operating system? Darwin Kernel Version 10.7.0: Sat Jan 29 15:17:16 PST 2011 com.bandlem.mac.zfs.fs (74.1.0)

Please provide any additional information below.

Same exact error using the same maczfs version on 10.7.1

Same problem with MacZFS-74.1.0 and OSX 10.5.8. I share my /Users on ZFS with Ubuntu 11.10 with native zfs boot on Linux. If I create a zvol swap partition on the Linux side then OSX will hang before reaching the login window.

Zvol seems to be an important feature to have working. Could you not for example format a zvol HFS+ and boot natively OSX?

Most of the code for zvols in maczfs appears to be commented out with only stubs left. Maybe someone with knowledge of the history of the code could explain the situation. Perhaps the rest of it should also be disabled.

The ZVOL format was never ported to Mac ZFS.

MacZFS has been discontinued. Please switch to https://openzfsonosx.org/
