[Solved] Pct start don't work (unable to detect OS distribution)

[chencho]

Hi all.

I have the nvem disk freeze.

After reboot, disks works again and I can make ssh and login via web.

But now all my vm's are stopped.

If I see the lo, I can see:

lxc pre-start with output: unable to detect OS distribution

I upgrade from 5 (with error) to 6, but the error still here.

It's the same with all the vm's (all are lxc)

Seems rpool was mounted before lxc start

I need to delete dir and then mount it

rmdir /rpool/vmdata/subvol-712-disk-0/dev/
rmdir /rpool/vmdata/subvol-712-disk-0/
zfs mount rpool/vmdata/subvol-712-disk-0

Now I can start my lxc containers.
