We don't know all events which happened there. I wonder why (if) state of network interfaces changed. Just in case, you can execute ip a
and verify that the current names match names in configuration files (probably /etc/network/interfaces
. Though it might not be needed, as I don't know from your post if you lost the networks access, or not. Anyway. Look at that last line ("Volume was not properly unmounted... Please run fsck"). I would take a closer look at that. Have you run fsck (probably fsck /dev/sde2
)? Depending on being it mounted or not, you could do that in this Proxmox system or in some "Live CD" environment.
