No network connection after "EXT4-fs (dm-1): Remounting filesystem read only" fsck repair

[alisosy]

Hi everyone,

Suddenly I noticed that my WebGUI isn't working anymore. I checked the server and found the error "EXT4-fs (dm-1): Remounting filesystem read only". I did a fsck of the boot drive, which led to being able to access commandline again. VM's are running fine, but WebGUI is still not working. Also no access to the Internet from the host. After checking networking status I found this " warning: cannot load "address" module: No module named 'pkg_resources.extern.jaraco' ". Anyone got an idea how to fix this?

pvedaemon and pveproxy are running without any error. Port 8006 is open.

Help would be greatly appreciated.

I’ve run into something similar before after an unexpected power event. The read-only remount usually means the system hit a disk or file system error. After running fsck, make sure you also reboot cleanly so services like pveproxy reload correctly.
If WebGUI and networking are still off, check /etc/network/interfaces
for corruption or missing configs, and reinstall pkg_resources with pip install --force-reinstall setuptools. By the way, at work we monitor network health using Openvault tools those analytics really helped us detect early signs of bandwidth or filesystem stress before things like this happened.
