Re: zroot won't mount after 9.0-RC2 - 9.0-RELEASE upgrade
To follow-up, testkernel mounted fine using the procedure from loader.4th(8): set kernel=testkernel unload boot-conf And the OS upgrade is now done, after a few more tweaks have been ironed out (the most interesting of them is a difference between /boot/testkernel and /boot/kernel, which were supposedly generated by the same 'make' command some time apart). Thanks again for the suggestions, all.

Re: zroot won't mount after 9.0-RC2 - 9.0-RELEASE upgrade
Okay. I tried booting from the 9.0-RELEASE cd into a shell and replacing /boot/zfs/zpool.cache on with the one generated by the CD's kernel. (I did that by running 'zpool import -R -o cachefile=/tmp/...' and then copying zpool.cache over that of the live system, in a manner similar to http://wiki.freebsd.org/RootOnZFS/GPTZFSBoot/9.0-RELEASE.) That didn't seem to have any effect: the 9.0-RC2 kernel can still boot, and the 9.0-RELEASE kernel still fails to boot, with the same error. FTR, here are the old/new zpool.cache files: % ls -al /boot/zfs/zp* -rw-r--r-- 1 root wheel 2308 Feb 15 16:43 /boot/zfs/zpool.cache -rw-r--r-- 1 root wheel 2052 Feb 15 16:41 /boot/zfs/zpool.cache.20120215rc2 Re George's suggestion -- I noticed a Can't re-use a leaf (geom_gpart_gpt)! error, in case it's relevant. I have also tried running: for i in 0 1 2 3 4 5; do gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 mfid$i done from the RC2 environment. RC2 still boots; the 9.0-RELEASE /boot/testkernel still doesn't. Thanks for the suggestsions.

Additional info: from the CD environment, 'zpool import' reports an old 'tank' pool on devices mfid[2-5]. (The 'zroot' pool uses mfid[0-5]p3.) Any further ideas, please? Thanks for all the suggestions so far. You are running ZFS version 4 while the default is 5 on 9.0-RELEASE --- Assuming your pool is called zroot ---This is the way to update your zpool.cache:--- Boot with 9.0-RELEASE and proceed with: #zpool import -o altroot=/mnt -o cachefile=/var/tmp/zpool.cache zroot #zfs set mountpoint=/mnt zroot #zfs set mountpoint=/mnt/usr zroot/usr #zfs set mountpoint=/mnt/var zroot/var #zfs set mountpoint=/mnt/tmp zroot/tmp ## Ignore any warnings## Now export the pool: #zpool export -f zroot Import the pool back and update the zpool.cache: #zpool import -o cachefile=/var/tmp/zpool.cache zroot #cp /var/tmp/zpool.cache /mnt/boot/zfs/zpool.cache Make sure that bootfs is set correctly: #zpool set bootfs=zroot zroot Now, unmount any ZFS datasets #zfs umount -af And fix mountpoints: #zfs set mountpoint=legacy zroot #zfs set mountpoint=/tmp zroot/tmp #zfs set mountpoint=/usr zroot/usr #zfs set mountpoint=/var zroot/var That should be enough to update your zpool.cache If this still doesn't work then you can upgrade your ZFS version to 5. Make sure you have backups first!!! Before unmounting your datasets issue a: zfs upgrade -a I remember doing something similar. It took me a few hours to figure everything out and repeated reboots to attempt to get it working. I believe what worked for me wasn't mounting it in /mnt, but actually mounting on / and making sure the cache file was in the zfs pool. I think I had to make a copy because zfs wanted to export the pool before shutdown which defeated the point. It was almost a year ago that I dealt with it. I'm 90% sure it's a cache file issue, and it's just getting it working properly. Note: I've never had a problem when upgrading from /usr/src, it was only when I was moving datasets to different drives, adding hard drives, and redoing my hard drive arrangement. ___ 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

Did you update the bootloader? Depending on when you installed the
system, it's possible your upgrading the zpool means the bootloader
can't read it.
Immediately after upgrading the zroot zpool I ran
gpart bootcode -p /boot/gptzfsboot -i 1 ${devices}
as instructed in /usr/src/UPDATING. I did not pass -b.
