|
|
Hi all -
It appears I have a 95% successful Gentoo install on a ZFS root. I created my own install CD using catalyst, releng specs, and adding zfs. I then combined https://github.com/ryao/zfs-overlay/blob/master/zfs-install and https://github.com/pendor/gentoo-zfs-install/blob/master/install/GentooInstall.mdown, so my workflow went as followed:
Code: |
from pendor's guide:
sgdisk --zap-all /dev/sda (repeat for sdb-sdf)
sgdisk \
--new=1:2048:133120 --typecode=1:EF02 --change-name=1:"grub" \
--largest-new=2 --typecode=2:BF01 --change-name=2:"zfs" \
/dev/sda #(repeat for sdb-sdf)
reboot w/ installCD
zpool create -m none -R /mnt/gentoo rpool mirror sda2 sdb2 mirror sdd2 sde2 mirror sdc2 sdf2
follow ryao's notes from #create rootfs to #install gptfdisk
skip making partitions and rebooting since I already did this above
install grub2, but for each drive (sda-sdf)
Then commented out fstab and installed software according to gentoo amd64 handbook.
When trying to unmount rpool, it refused because /mnt/gentoo was busy, but I could find no processes using it, so I just crossed my fingers and rebooted because I had to take my kid to daycare :)

The last reboot resulted in a system booting off ZFS - yay. The only things I noted were:
1. Grub took a long time to start up. Is it because I installed grub onto each drive? Is there a way around this? It doesn't look like there are any bootflags marked for partitions since ZFS handles it all. Or is it just a consequence of having to do some Grub2/ZFS magic?
2. When shutting down, I again notice error messages about / being busy, ZFS unable to unmount it, but shutdown continues anyway. Is this a bug, should I be worried, or just not care since I have all the other ZFS coolness available.
Thanks - and thanks to both pendor and ryao for the guides. |
