https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=192184 --- Comment #15 from Dave Cottlehuber <dch@skunkwerks.at> --- @pablo I'm successfully booting direct from ZFS, here's what I learned: 1. it must be a UEFI-enabled boot image (10.1 pre-releases are good) 2. zfs must have a dataset with mountpoint=/ and your usual /boot/* stuff in here. Note this is not actually where the kernel will be loaded from, but it's where I keep the master copy so it's safely versioned on zfs. 3. the zpool* must have property bootfs set to point to that dataset, for example my default bootfs is: bootfs=zroot/ROOT/default 4. you must have a FAT-style EFI partition, with the kernel modules & all boot loader stuff in it. I am not exactly sure if there's a way to trim this down and have a smaller set. You *must* copy this across from within FreeBSD, I was unable to boot FreeBSD if I used either a linux system to transfer, or OSX -- the FAT 8.3 path mangling screwed things up. I keep the master of /boot in ZFS but rsync it across to the EFI partition. My /boot/loader.conf is: # cat /efi/boot/loader.conf # master in zfs:/boot/loader.conf but # actually loaded from /EFI FAT partition # remember to keep settings mirrored # mkdir -m 0700 /efi # mount -f msdosfs /dev/diskid/DISK-Z1F21XGNp1 /efi # rsync -harv /boot /efi/boot --exclude=\*.symbols --del --partial --inplace kern.geom.label.disk_ident.enable="0" kern.geom.label.gptid.enable="0" kern.vty="vt" zfs_load="YES" vfs.root.mountfrom="zfs:zroot/ROOT/default" my EFI partition is (directories only): # tree -qcd . ├── boot │ ├── defaults │ ├── kernel │ ├── modules │ ├── zfs │ └── firmware └── EFI ├── APPLE │ ├── EXTENSIONS │ ├── FIRMWARE │ └── CACHES │ └── CAFEBEEF └── refind ├── icons ├── drivers_x64 └── tools_x64 As this is still a mac there is apple cruft in here. Working on getting rid of that. This might be better discussed on one of the mailing lists BTW rather than in a resolved ticket ;-). -- You are receiving this mail because: You are the assignee for the bug.
