List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 21 Jul 2017 22:43:42 -0000 Since I found out that I can't run a Samba directory server in a jail, I've had the setup of a bhyve on my list. I had toyed with Bhyve 6 or 8 months ago, and still had the images, so I zfs cloned one and set about a source upgrade. This ignomineously hung. So... I upgraded the host to 11.1-RC3, and I reinstalled a fresh guest from the 11.1-RC3 install CD. The guest uses UFS2 on a 40G disk, the server is an AMD 9590 with 32G RAM and a 40T ZFS array. After installation, I started the guest again with 1G ram, 4 processors (of the 8 on the source CPU) and tried a buildworld again. This time the guest crashed and rebooted. What should be next steps here? This is repeatable. The host is stable (it can makeworld -j32 in about 25 minutes ... so it's hardware seems good). Is this an AMD bug? Is it bad to use ZFS ZVols?
