PVE 7.2.7 suddenly one bond does not up after reboot

Hi folks
We are running a six member cluster with a several network connections trough enterprise grade switching.
  • GbE (copper) for HA
  • 2x2 Port SFP28 to two Switches as Bond (LACP 802.3ad)
    • one bond for Data/Mgmt
    • one bond for Storage
This setup worked well until about two or three weeks. After a restart of a node (Maintenance reboot), the bond1 will suddenly not come up automatically anymore. Needs to be upped manually. This is not a big issue, but needs attention on Maintenance.
Any hint, why this occurs?
The setup is identically, HPE Hardware, Network Card BCM57414
  • card 1 / port 1 --> bond0 through switch 1
  • card 1 / port 2 --> bond1 through switch 1
  • card 2 / port 1 --> bond0 through switch 2
  • card 2 / port 2 --> bond1 through switch2
 
Any hint, why this occurs?
for now not really - but check the journal since the reboot occurred (`journalctl -b` ) - usually this gives a hint at what's not working

if you don't find the issue:
* post the journal (anonymize only what you must)
* post your /etc/network/interfaces

I hope this helps!

perhaps the network device naming of one nic has changed? (I've see one case during an update in the last time)
But in this case you should get an error on manually start too…
Do you have an auto entry for all devices?

Will need to reboot the nodes to see, if it happens and to go into the journalctl -b, at the moment I don't see any useful infos in the logs of the 2 machines that have been rebooted.
Just very early:
Code:

The hung message appears two additional times.
After, the enslaving of the devices seems ok

As I said, that happens only to bond1, bond0 is coming up normally.
The only difference in between is that bond1 is on jumbo frames.
And the behavior is new, it did work until soon. And we didn't change anything on the network. Just the regular patches from Debian/ProxMox.
 
the other variation is that you are tagging vlan 600 and an ip address explictly on bond1.600 where vlan 100 is configured differently.

the documentation suggests
auto bond0 iface bond0 inet manual bond-slaves eno1 eno2 bond-miimon 100 bond-mode 802.3ad bond-xmit-hash-policy layer2+3 iface bond0.5 inet manual auto vmbr0v5 iface vmbr0v5 inet static address 10.10.10.2/24 gateway 10.10.10.1 bridge-ports bond0.5 bridge-stp off bridge-fd 0
 
Ok, yesterday we patched all nodes and they came up without a flaw.
Our network engineer told, that he will check if there is perhaps something different on the switches which the system engineers didn't found.
We'll keep an eye on it and will follow up.
