After running the test on top of ZFS I destroyed the pool and created a freebsd-ufs partition on the "empty" drive. Here the output of "gpart show" => 34 976773101 ada0 GPT (465G) 34 976773101 1 freebsd-ufs (465G) I then labeled the partition ada0p1 with gjournal and created a new UFS2 on top of ada0p1.journal with journaling enabled (-J). Then the partiton was mounted and the iozone test was started inside. The command was "iozone -RA -g 16G". When starting to write 1GB of data in 64k chunks, the system crashed (check the - literally - screenshot attached). The system wasn't even able to write more than 2GB of the 8GB memory back to disk before it completly froze. I did the exact same test with this system and ZFS on the empty disk and everything worked as expected. I wasn't able to attach the screenshot, so I uploaded it here: http://img515.imageshack.us/img515/9622/gjournal.jpg If you have any questions just contact me. KR, Grimeton >How-To-Repeat: - Setup 9.0-RELEASE on one harddrive - Fetch ports, compile benchmarks/iozone - create a GPT scheme on another, empty, disk - setup a freebsd-ufs partition - label the partition with gjournal - create UFS2 on top of the journaled partiton with journaling enabled (-J) - mount the new fs to /test - cd to /test - start iozone like "iozone -Ra -g 16G" - wait and watch it crash >Fix: No clue. >Release-Note: >Audit-Trail: >Unformatted:
