install on zfs

[dieterarn]

Hi all,

I thought i move my posting on zfs over here (see previous posts in the 16.7 section https://forum.opnsense.orgindex.php?topic=3543.0) sinse, clearly zfs on 16.7 is impossible (and maybe 17.1 too). I thought I'd at least have a try at capturing the boot messages of a newly converted opnsense box booting up  - i did it with a "host pipe" in virtualbox and picked up the "socket" in minicom on the cli of my host machine - it this is useful to someone with madder skillz than i i'll be glad :-)

I thought of some more stuff to try like: duh why don't i try to apply the info from the guide on modifying pfsense to work with zfs that i had first found here:

https://forum.pfsense.org/index.php?topic=94656.0

so i cloned the virtual machine i've been playing with and booted into the live cd mode of freebsd (i found that idea at http://serverfault.com/questions/616991/freebsd-10-wont-boot-to-zfs-root-after-power-failure)

and then took a look at mounting the zfs file system since the why it was done on the server fault page wouldn't work for me :-( . I had a look logical stuff like https://www.freebsd.org/doc/handbook/zfs.html ,http://docs.oracle.com/cd/E19253-01/819-5461/, and http://solarisinternals.com/wiki/index.php/ZFS_Troubleshooting_Guide before i poked around, generated an error and found : https://forums.freebsd.org/threads/43983/

i modified the suggested command a bit:

Code: [Select]

zpool import -f -o altroot=/mnt zroot since i just wanted the main pool (my volume was also called zroot but if you don't know it you can do just

Code: [Select]

zpool import and zfs will list all the pools it can see...)

after that i tried to start applying the steps from the pfsense article excluding the step where you mount the file-system since i had oviously just done that:

Code: [Select]

sed -i -e "s:cdrom:pfSense:" /mnt/etc/platform
mkdir -p /mnt/cf/conf
cp /mnt/conf.default/config.xml /mnt/cf/conf/config.xml
cd /mnt
rm -rf conf/
ln -s cf/conf ./conf
mkdir /mnt/tmp
chmod 1777 /mnt/tmp
uh oh.

Code: [Select]

/mnt/etc/platform dosn't exist. nor does:

Code: [Select]

/mnt/conf.default/config.xml
eventually i tracked down that opnsense has moved them. For ex: https://github.com/opnsense/core/commit/55db8dab0f19c5a9e882957087571f650608cfec shows that

Code: [Select]

/conf.default/config.xml is now probably

Code: [Select]

/usr/local/etc/config.xml and similarly https://github.com/opnsense/tools/commit/132641c826914fccf87b1ac433b39d3ec09c9a46 shows that

Code: [Select]

/etc/platform is now (maybe)

Code: [Select]

/usr/local/etc/platform
so applying those changes i got something like:

Code: [Select]

sed -i -e "s:cdrom:OPNsense:" /mnt/usr/local/etc/platform
mkdir -p /mnt/cf/conf
cp /mnt/usr/local/etc/config.xml /mnt/cf/conf/config.xml
cd /mnt
rm -rf conf/
ln -s cf/conf ./conf
mkdir /mnt/tmp
chmod 1777 /mnt/tmp
... which still doesn't work. I assume cf stands for compact flash and cdrom stands for a read only file system. beyond that i don't have as much insight into what is going on as i would like to have... Feels kind close though... *sigh*.

Hi there,

Thanks for looking into this! I don't see why most of the modification is needed. The simple truth is that the file system cannot be found when /usr/local/etc/rc is invoked:

https://github.com/opnsense/core/blob/master/src/etc/rc#L20

When you can make it mount the ZFS before it runs any other commands you're done, no need to fiddle with config.xml or "platform", which got removed a long time ago.


Cheers,
Franco
