Re: Problem with ZFS version 15
After reinitialized my gpt scheme, i can successfully import my zpool. After this there was a little bit trouble with my zpool.cache and booting from my pool, but now it works.

No it won't touch your data (assuming you were using GPT rather than a whole disk directly in the past) as long as you create/destroy GPT partition tables/scheme on the disk. Only the partition table itself gets changed which won't modify your on-disk data. Cheers, - -- Xin LI delp...@delphij.nethttp://www.delphij.net/ FreeBSD - The Power to Serve!

Problem with ZFS version 15
Hi, i updated my 8.1-PRERELEASE to ZFS version 15. 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.
