Hi, I've got a problem with booting zfs-on-root FreeBSD 9.2-PRERELEASE. I'm getting: ZFS: i/o error - all block copies unavailable ZFS: can't read MOS of pool klawisz gptzfsboot: failed to mount default pool klawisz Machine is VM running under KVM on Proxmox 2.3-13. VM has 8 GB of RAM, 400 GB of local storage with SCSI Controller type: Default (lsi). I'm not sure what I did to make this VM unbootable. I've installed 9.2-PRERELEASE, did source based upgrade to r253470, mergemaster, reinstalled bootcode and rebooted. To this point VM was bootable. Then I did installworld from /usr/src to ezjail's basejail (ezjail-admin update -i), did mergemaster for jails, install some ports - none of this should mess with booting. I rebooted VM and got unbootable system. When I boot from liveCD I can import this pool (scrub shows no errors), mount it, chroot to it, and work with it. I just can't get it to boot. Some information about the system: http://pastie.org/private/mtfhkx0wx0vve29xn0plw I've tried to downgrade to r252316 - no luck, system is still unbootable. Any hints how to go from here? -- best regards, Lukasz Wasikowski
