Hello,

I want to boot off a ZFS pool (version 13) on an USB stick for testing purposes. But I'm stuck with the bsdlabel bootstrap code size... I'm using a 2 hours old CURRENT.

# kldload usb2_storage_mass # kldload zfs # dd if=/dev/zero of=/dev/da0 bs=512 count=32 # fdisk -BI da0 # dd if=/dev/zero of=/dev/da0s1 bs=512 count=32 # bsdlabel -wB -b /boot/zfsboot da0s1 bsdlabel: boot code /boot/zfsboot is wrong size

Is what I'm trying to do with bsdlabel wrong ? I previously tried with the default bootstrap code but I had an (expected) "boot: Not ufs" error at boot.

PS : I'm not subscribed to this list.

The process for install zfsboot is a bit manual (and undocumented). Try something like this:

# dd if=/boot/zfsboot of=/dev/da0s1 count=1 # dd if=/boot/zfsboot of=/dev/ds0s1 skip=1 seek=1024

Alternatively, you might try using the brand new support for GPT that I committed yesterday:

# gpt create -f da0 # gpt boot -b /boot/pmbr -g /boot/gptzfsboot da0 # gpt add -t freebsd-zfs da0 # zpool create mypool da0p2

It works !

Now I'm stuck at loader(8) prompt.

That's a me too.

I tried this under vmware with LOADER_ZFS_SUPPORT=yes on make.conf: # gpart create -s gpt ad0 # gpart add -b 34 -s 128 -t freebsd-boot ad0 ad0p1 added # gpart add -b 162 -s 15078327 -t freebsd-zfs ad0 ad0p2 added # gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ad0 # zpool create tank ad0p2 # zpool set bootfs = tank tank

lsdev on loader shows: cd devices: disk devices: disk0: BIOS drive c: disk0p1: FreeBSD boot disk0p2: FreeBSD ZFS pxe devices: zfs devices:

Any hints?

I'm trying to figure out why loader doesn't see my zfs pool and here's what I got:

FreeBSD/i386 boot Default: tank:/boot/loader boot: status pool: tank config: NAME STATE tank ONLINE ad0p2 ONLINE

I added some printfs on loader\main.c:

guid = kargs->zfspool; unit = zfs_guid_to_unit(guid); if (unit >= 0) { sprintf(devname, "zfs%d", unit); setenv("currdev", devname, 1); }

and guid returns the correct guid for my pool but unit returns -1 which by looking at zfs_guid_to_unit means something is not right.

Any pointers Doug?

It looks like loader didn't manage to find the pool for some reason. This probing process happens in sys/boot/zfs/zfs.c in the function zfs_dev_init(). Its supposed to taste all the available disks and partitions for the presence of a ZFS pool. The actual tasting process happens in vdev_probe().

Paul Saab just commited this: http://svn.freebsd.org/changeset/base/185711 It's working now! Thank you very much to both! :-D
