The patch http://people.freebsd.org/~mm/patches/zfs/v15/head-v15-v3.patch applies fine and after reboot i upgrade my pool successfully to version 15. Now, after a new reboot the bootloader can't boot from version 15, it supports only 13. Well, i build a bootable usb pen with 8.1-PRERELEASE and ZFS version 15, boot from it and apply a new bootloader: gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ad0|ad1. After this, i've lost my gpt scheme ! gpart show ad0 says "gpart: No such geom: ad0". How can i recover my gpt on ad0 and ad1 ? I'm running a zfs mirror on ad0 and ad1. If you have previous saved gpart information (e.g. start/end) then you can safely destroy and re-create the GPT partitions without destroying the data. Note that you may need to backup and dd the first and last sector of your hard drive before proceeding. Cheers, Cheers, - -- Xin LI http://www.delphij.net/ FreeBSD - The Power to Serve!
