I Can't reboot my server anymore

Carlton372 · Dec 18, 2018

Hi Everyone,

I'm having a problem, I'm on proxmox 5 on Debian and everything worked perfectly until I decided to remove a port from the configuration and now my server won't reboot. I can access it via rescue mode. Can someone please help understand what is wrong with? I changed the IP address with XXX

Code:

# network interface settings; autogenerated
# Please do NOT modify this file directly, unless you know what
# you're doing.

# If you want to manage part of the network configuration manually,
# please utilize the 'source' or 'source-directory' directives to do
# so.
# PVE will preserve these directives, but will NOT its network
# configuration from sourced files, so do not attempt to move any of
# the PVE managed interfaces into external files!

Does not reboot or you don't have access via network any more?

If the latter, check ip configuration which is in effect after connecting by

Code:

ip addr

and correct it.

If it really does not boot any more have a look at the console what is reported in the startup process.

Hi Richard,
Thank you for your reply, It didn't ping via IP and I had to had it reset (Kimsufi Server) in Rescue mode, It finally booted via HDD. But I never understood what the problem was. This thread can be closed now
