I just installed NixOS on a machine that uses ZFS for the filesystem. The install was clean (after lots of fiddling around), but I’m getting an error when I boot. The error says:
starting decive mapper and LVM...
importing root ZFS pool "zroot"...
Enter passphrase for 'zroot':
1 / 1 key(s) sucessfully loaded
mounting zroot/root on /...
mounting zroot/nix on /nix...
mounting zroot/var on /var...
stage 2 init script (/mnt-root//nix/store/...<lots of chars>.../init) not found
An error occurred in stage 1 of the boot process, which must mount the root filesystem on`/mnt-root' and then start stage 2.
Here’s a pic:
There’s also some error messages about invalid report_size. No idea what that means.
My first guess is that something isn’t getting mounted in the right place, but I’m not sure what. Does anyone have any idea what might be going on? Happy to share configuration files, if needed.
Thanks in advance.
Pretty much impossible to know what’s going wrong without seeing the configs.
Roger that. Here are my configuration files.
