The patch http://people.f= reebsd.org/~mm/patches/zfs/v15/head-v15-v3.patch applies fine and after reb= oot i upgrade my pool successfully to version 15. Now, after a new reboot t= he bootloader can't boot from version 15, it supports only 13. Well, i buil= d a bootable usb pen with 8.1-PRERELEASE and ZFS version 15, boot from it a= nd 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 "g= part: No such geom: ad0". How can i recover my gpt on ad0 and ad1 ? I'm run= ning 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. > I don't have such a backup, only the whole disk for now. Everything else wh= at can i do ? What if i initialize the gpt header: "gpart create -s GPT ad0= " ? Do i lost my data ?
