OLVM (ol8.x) - *help* some nodes we cannot do any network changes! JSON-RPC error:Interface bond0.505 has unknown parent: 6

morgan coxSep 19 2023 — edited Sep 19 2023

We have a standalone engine and several nodes. I tried to add a new VLAN to some nodes - Some of the nodes I am unable (some are ok) the ones that fail have an error in the engine - for example

VDSM node1 command HostSetupNetworksVDS failed: Internal JSON-RPC error: {'reason': 'Interface bond0.505 has unknown parent: 6'}

Other nodes are fine..

All nodes are using bond0 - but the ones that fail show a number as 'base-iface' when using # nmstatectl show instead (i.e ‘6’ above) instead of the name bond0 …

i.e

Working node:

$ nmstatectl show |grep base-iface

base-iface: bond0
base-iface: bond0
base-iface: bond0
base-iface: bond1

Non working node :

$ nmstatectl show |grep base-iface

base-iface: '6'
base-iface: '6'
base-iface: '6'
base-iface: '11'

Any ideas why ??

The nodes i cannot change networking on also show in vdsm logs

2023-09-19 09:29:48,117+0000 INFO (jsonrpc/0) [jsonrpc.JsonRpcServer] RPC call Host.setupNetworks failed (error -32603) in 0.77 seconds (__init__:312)

Any help to debug this would be good - i think all nodes have latest ovirt/olvm updates.

Previously all nodes I could change networking (i.e i must have in order to have added previous VLANs, etc)
