Good day!

Problem: after rebooting the server version 11.1, an error flies to the screen (see screenshots)
unable to remount devfs under /dev

6118


Tell me, is there a solution to restore server load?

I'm a little puzzled by the unable to unlink /dev/dev. And I'm wondering how it loads the kernel if it can't find the filesystem (the kernel is stored on the filesystem).

What filesystem is the server using? UFS? Anything advanced like full disk encryption? Have you tried booting a rescue image? Are the disk(s) still good?

using - ZFS

Tried to be started on the copy of the boot catalog from an image, the decision came true

I ran into this same issue on a custom install of FreeBSD. The more informative error turned out to be mountroot: unable to remount devfs under /dev, which led me to believe that my root filesystem wasn't being mounted correctly. In fact, it wasn't and it was due to an incorrect entry in /boot/loader.conf:

The entry vfs.root.mountfrom="zfs:zroot" should have been vfs.root.mountfrom="zfs:zroot/ROOT/default", which conforms to FreeBSD's default ZFS Boot Environment layout on used for ZFS Root installs.
