Re: ZFS booting without partitions
OK, so I've got my next little adventure here to share :-) ... after reading Your posts I was very eager to give the whole boot-zfs-without-partitions thing a new try. My starting situation was a ZFS mirror made up, as I wrote, of two GPT partitions, so my pool looked like: phaedrus# zpool status pool: tank state: ONLINE scrub: none requested config: NAMESTATE READ WRITE CKSUM tank ONLINE 0 0 0 ad6p4 ONLINE 0 0 0 ad4p4 ONLINE 0 0 0 it was root-mounted and everything was seemingly working fine, with the machine surviving several bonnie++'s, sysbenches, and supersmacks concurrently for many hours (cool!). So to give it another try my plan was to detach one partition, clear the gmirror on the UFS boot partition, make a new pool made out of the free disk and start the experiment over. it looked almost like this: zpool offline tank ad4p4 zpool detach tank ad4p4 gmirror stop gmboot (made out of ad6p2 and ad4p2) gmirror remove gmboot ad4p2 then I had to reboot cause it wouldn't give up on the swap partition on the zpool. That's where the first problem began: it wouldn't boot anymore... just because I removed a device? In this case I was stuck at the mountroot: stage. It wouldn't find the root filesystem on zfs. (this happened also when physically detaching ad4). So I booted off a recent 8-CURRENT iso DVD, and although the mounroot stage is, iirc, at a later stage than the loader, I smelled it could have something to do with it and downloaded Adam's CURRENT/ZFS loader, put it in the appropriate place on my UFS boot partition... note: From the CD, I had to import the pool with zpool import -o altroot=/somewhere tank to avoid having problems with the datasets being mounted on top of the 8-fixit environment's /usr ... Ok, rebooted, and whoops it would boot again in the previous environment. So... from there I started over with the creation of a ZFS-bootonly situation on ad4 (with the intention of zpool-attaching ad6 later on) dd if=/dev/zero bs=1m of=/dev/ad4 count=200 (just to be safe, some 'whitespace'..) zpool create esso da4 zfs snapshot -r t...@night zfs send -R t...@night | zfs recv -d -F esso (it did what it had to do - cool new v13 feature BTW!) zpool export esso dd if=/boot/zfsboot of=/dev/ad4 bs=512 count=1 dd if=/boot/zfsboot of=/dev/ad4 bs=512 skip=1 seek=1024 zpool import esso zpool set bootfs=esso esso the mountpoints (legacy on the poolfs, esso, and the corresponding ones) had been correctly copied by the send -R. Just shortly mounted esso somewhere else, edited loader.conf and fstab, and put it back to legacy. shutdown -r now. Upon boot, it would wait a while, not present any F1/F5, and booted into the old environment (ad6p2 boot partition and then mounted tank as root). From there, a zfs list or zpool status just showed the root pool (tank), but the new one (esso) was not present. A zpool import showed: heidegger# zpool import pool: esso id: 865609520845688328 state: UNAVAIL status: One or more devices are missing from the system. action: The pool cannot be imported. Attach the missing devices and try again. see: http://www.sun.com/msg/ZFS-8000-3C config: essoUNAVAIL insufficient replicas ad4 UNAVAIL cannot open zpool import -f esso did not succeed, instead, looking on the console, I found ZFS: WARNING: could not open ad4 for writing I repeated the steps above two more times, making sure I had wiped everyhing off ad4 before trying... but it would always come up with that message. The disk is OK, the cables too, I triple-checked it. Besides, writing to the disk with other means (such as dd or creating a new pool) succeeded... (albeit after the usual sysctl kern.geom.debugflags=16 ...) well for now I think I'll stick to the GPT + UFS Root + ZFS Root solution (I'm so happy this works seemlessly, so this is a big THANX and not a complaint!), but I thought I'd share the latest hickups... I won't be getting to that machine for a few days before restoring to the gpt-ufs-based mirror, so if someone would like me to provide other info I'll be happy to contribute it. Big Regards!

Just mentioning this in case it saves someone else some time. I'm real pleased it works at all. If someone has the time to track down the differences I'll MFC them. I'm not using ZFS boot at the moment so I have no way of testing.

Re: ZFS booting without partitions (was: ZFS boot on zfs mirror)
I encountered the same symptoms today on both a 32bit and 64bit brand new install using gptzfsboot. It works for me when I use a copy of loader from an 8-current box with zfs support compiled in. I haven't looked into it much yet but it might help you. If you want, you can try the loader I am using from: http://www.egr.msu.edu/~mcdouga9/loader On Thu, May 28, 2009 at 10:41:42PM +0200, Lorenzo Perone wrote: On 28.05.2009, at 21:46, Mickael MAILLOT wrote: hi, did you erase gmirror meta ?

I obtained the same result with FreeBSD 7 stable. I installed first a new system in a scsi disk with ufs I put LOADER_ZFS_SUPPORT=yes in /etc/make.conf, updated src and made buildworld without trouble. I built a new kernel, installed it and installed new world. Until here, that's all right Then, I tried with a PATA hard drive, ad2 I resetted the mbr and the partition table with dd if=/dev/zero
