ZFS Mounting local filesystem ; eval : zfs not found - eval: touch not found - /etc/rc : date not found

Hello to everyone.

My main FreeBSD 13.1 installation froze at some point of the booting process showing these messages :

Code: 
Mounting local filesystem
eval : zfs not found
eval: touch not found
/etc/rc : date not found

I have no idea what's wrong and why. Please,can someone give me some suggestions to help me to fix these errors ? because I can't use ianymore that installation since those errors froze it totally. Maybe the solution is here :


but I don't know if those commands,adapted to my situation,can help to fix the errors or they could further damage it. I don't want to risk issuing commands that I don't understand. Very thanks.
 
Looks like your root filesystem is missing /bin, /usr/bin and /sbin. Some of it is still there because it does start the /etc/rc script which means that /sbin/init and /bin/sh are still there. But /usr/bin/touch, /sbin/zfs and /bin/date seem to have disappeared. Boot to single user mode and investigate further.

In a pinch you could extract those files from base.txz from the installation media.
 
i remember a similar post when the problem was the incorrect dataset was mounted as root
which was missing /bin and stuff
2 dataset had mountpoint set to / and canmount on

touch,zfs and date are on the proper places.

I think that this could be compatible with what I did today. Can you help me to fix it ?

No one can help here ? If I don't restore that zfs pool ? I can't do anythng else. All my important data are there. I'm totally lost.
 
Boot to single user, then have a look at zpool list, I'm wondering if both pools are loaded. The name and mountpoints of nomadbsd-zroot appear to look good, no clashes or conflicting mounts there. You could simply try to export that other pool, if only to make sure it's not in the way.

I'm assuming that zroot pool is the one with your data? Why are they all mounted on /mnt? Is that because of an import with a install disk?
 
Like i said in your previous post verify :
- zpools have different names
- you don't do overmount of directories which contain already data when you do "zpool import". (I'm almost certain you do this)
- when you import pools with identical dataset mountpoints as the host use altroot import.

Actually I'm on the nomadbsd system. And zfs list shows that the zroot pool (where I have all my data) is not mounted. I have also turned off the disk where I have installed nomadbsd and I have booted my third freebsd installation,thinking that this might have been enough to fix the conflict. But unfortunately it hasn't. I'm almost sure that the conflict arises because I have set the canmount of the zroot pool in the wrong way. How can reverse it ?

maybe :

Code: 
zpool import -f -R /mnt/zroot zroot
zfs set canmount=off zroot
zpool export zroot

?
 
Boot something, import the offending pool, set canmount back to 'off', export pool. Boot system normally.
 
Useful command: zfs list -r -o name,canmount,mountpoint zroot

Double check your mountpoints too.

For reference, this is a fairly standard install:

At the moment I'm trying to fix that error,but don't forget that what I want to do is,when I'm running NomadBSD,to mount the zpool zroot showing all the directories there.
 
I've rebooted. Unfortunately it didn't work :

Basic troubleshooting guide is to cut away everything that's not explicitly required. Export all the other pools so you're only left with the important one. Do NOT import the others until you've got the zroot pool properly booting again. You are adding a lot of unnecessary clutter and complexity which only leads to more confusion, bring it down to the basics. Then fix any issues that may arise. Once you have that system back up and running properly again should you consider adding the various other pools. Work methodically, take it step by step. Checking each step before moving onto the next.
 
Everytime I reboot the PC and I go with nomadbsd,I don't see different pools than the nomadbsd-zroot pool. So I have nothing to export. Below you see what I see now. I have just rebooted the PC and I haven't mounted any external pool.

/me looks at the top of the screen. Hmm, it says FreeBSD forums there, for a minute I though I had accidentally moved to the NomadBSD forums. That zroot is the broken FreeBSD install, right? Then why are booting NomadBSD?
 
Yes,the zroot pool belongs to the FreeBSD 13.1 system,not to the nomadBSD system. I'm "working" on NomadBSD because I'm experimenting with bhyve. Yesterday I needed to get some files from the FreeBSD system and I tried to mount it (while I was on Nomad). I gave a wrong command and I started to see that error. Actually I can't boot FreeBSD / ZFS anymore. I'm forced to go with Nomad or with another FreeBSD installation that I have,which has been installed on a UFS fs.
