Re: ZFS on MBR does not boot at all
I had to set up ZFS on MBR lately. Since I'm lazy I wrote a script for that. Maybe it would suit your needs (it's very simple though). https://bitbucket.org/ukaszg/freebsd-zfs-on-mbr-installer 2013/5/9 Giorgos Keramidas : > On Sun, 05 May 2013 17:56:49 -0500, Joshua Isom wrote: >> On 5/5/2013 3:20 PM, Giorgos Keramidas wrote: >>> Hi David, >>> >>> Thanks for following up with what the real problem was.

The original post was about an MBR partition table. Some modern laptops (mine is one) do not boot successfully from a disk with a GPT partition scheme, unless the boot loader is EFI-capable (which ours isn't). So you have to use an MBR-style partition table. In those cases the note is still useful to see. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

Hi David, Thanks for following up with what the real problem was. I updated the Wiki to include this: Note that partition order is important. It seems that zfsboot requires the freebsd-zfs partition to be the first, so make sure you add if first, before your swap partition. Cheers, Giorgos pgpAGlS_lM5GA.pgp Description: PGP signature

ZFS on MBR does not boot at all
Hello, I would like to use ZFS over MBR for multiboot purposes. I've followed that guide https://wiki.freebsd.org/RootOnZFS/ZFSBootPartition but it does not boot at all. The loader does not show up after choosing FreeBSD in the boot0 loader. The _ prompt appears but nothing starts. I've found many people over the web having the same problem but unfortunately no one found a solution. I think the offensive commands are ones with dd and zfsboot.
