How do I mount a Fedora 25 partition on another Linux distro?

On my Ubuntu 16.04 and Arch Linux installations whenever I try to mount a freshly-made Fedora 25 partition I get the error:

mount: unknown filesystem type 'LVM2_member'

On both such systems I have LVM2 installed and I have started the lvm2-lvmetad service and socket with systemd. I saw this answer at AskUbuntu but it wasn't helpful to me as I only have one LVM2 partition. My root partitions for Ubuntu and Arch Linux are ext4 partitions. Any ideas what I have to do to overcome this problem?

Why would I want to mount this partition on another distro? Simple, Fedora 25 has no proprietary firmware (which while it can be a blessing in this case it is anything but as my laptop has a Broadcom chip) in its default installation and hence on a laptop with a Broadcom chip it has no WiFi. So in order to get this WiFi I need to install proprietary firmware to Fedora 25 (via a chroot) from a distribution that does have the necessary firmware installed (and hence can access my WiFi).

The answer was quite simple. It was provided at AskUbuntu. Merely run:

 fsck -p /dev/fedora/root
 mount /dev/fedora/root /mnt

where /mnt is to be replaced with wherever you wish to mount your Fedora partition too on your presently-running system.

scottro gravatar image may offer help. I don't have any multi boot machines with LVM, so am unable to test. is more recent and makes more sense to me. It may also be that your filesystem is xfs and neither the Ubuntu nor Arch have support for it by default. (I don't know that they don't, it's just a hypothesis).

If this is a new installation, I would just reinstall using standard partitions. LVM is not an unreasonable default for RHEL, where many servers make use of it, but for a single or dual disk laptop or desktop, can over complicate things for those not used to it. If, after doing a reinstall, If it still won't mount, then you know the issue is XFS support for Ubuntu and Arch.
