Trying to elevate OVH dedicated server
Was just wondering, i'm trying to elevate my OVH dedicated server from Cloudlinux v7 to v8 but i'm getting this error:
2023-12-08 06:48:33 [WARN] *** Elevation Blocker detected:
Your machine has multiple network interface cards (NICs) using kernel-names (ethX).
Since the upgrade process cannot guarantee their stability after upgrade, you cannot upgrade.
Please provide those interfaces new names before continuing the update.
What should I do to resolve this issue?
Comments
Seems like you should
Try renaming them
eth0 -> nic0
eth1 -> nic1
I can't rename them though as they are controlled by cloud-init
Don't know too much about cloud-init, what part of cloud-init is preventing you from changing the names on them? As everything I can see in the documentation for it seems to imply that the
set-namevariable can be used for network interface names.https://cloudinit.readthedocs.io/en/latest/reference/network-config-format-v2.html
Well for example the ifcfg-eth1 doesn't even exist, I already tried creating that file and renaming it but that change doesn't apply when I reboot the server so its reading stuff from somewhere place.
I thought of completely disabling automatic network configuration and created this file /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg to do that.
I've also adjusted my ifcfg-eth0 file and changed BOOTPROTO from dhcp to static and added the IP & netmask in the file.
But i'm not sure if this is the correct way or if I will just break everything.
A quick google showed someone had a similar issue with the changes not applying to ifcfg-eth1, does adding
ONBOOT=yesto/etc/sysconfig/network-scripts/ifcfg-eth*work?https://unix.stackexchange.com/questions/68295/use-of-etc-sysconfig-network-scripts-ifcfg-eth-files
Nothing seems to apply to eth1/eth0, they not controlled by /etc/sysconfig/network-scripts/ so nothing defined there applies.
Wouldn't it be much easier if you back up the server, reinstall Cloudlinux v8 and go back to the backup?
Not in this case unfortunately!
Do you have something like net.ifnames=0 in grub configuration?
I got really close to succeeding with elevate st OVH. But, in the end I gave up. The old trusty method works best = get a new server, install/setup your cpanel stack on the version you want all fresh and new. Use Transfer Tool to migrate your accounts from old panel to new. Delete the old server and old licenses. It's the safest and easiest route to go imo.
Maybe you implemented the wrong steps during the rename process:
Here are the exact steps:
1) Identify your network interfaces by running: ifconfig | grepeth[0-9]
2) Edit the udev rules file: vi /etc/udev/rules.d/70-persistent-net.rules
3) Modify the last parameter of each rule to assign desired names to the cards.
4) rename the previous files that used the old card names. Run:
cd /etc/sysconfig/network-scripts/
mv ifcfg-eth0 ifcfg-ens192(your desired name)
mv ifcfg-eth1 ifcfg-ens224
Open each renamed file and update the DEVICE parameter to match the new name:
vi ifcfg-ens192
Change DEVICE=eth0 to DEVICE=ens192 and save
Repeat for the other file (ens224).
After this, interfaces should be renamed.
