Failed to start node (12) (and some kind of workaround)
Posted: Mon Jul 30, 2018 9:17 am
OK, so I made some research and there's several topics with this problem. So here's how I resolved this (this is not a panacea of course and I'm posting this mostly like some kind of a bugreport and as a possible (in some cases) workaround ).
First of all, I have EVE 2.0.3-86 on ESXI 6.0.
So I have serveral dynamips nodes (c7200-adventerprisek9-mz.152-4.S6) in my lab which worked like a charm, but one morning some of them failed to start with
This is what I saw in logs:
At first I tried to wipe the node but it didn't really help. (Permissions were, of course, fixed as well).
It seems that when we start node unl_wrapper tries to delete interfaces listed above, but it's not able to delete it: this is what happens if we try to perform it from cli
But it's possible to delete it this way:
After you remove all the problem interfaces listed in logs, your node will be able to start succesfully.
FYI:
