Hi

 

on each node customize these 3 configs  ?

systemctl stop petasan-file-sync

/etc/hosts
/opt/petasan/config/cluster_info.json
/opt/petasan/config/node_info.json

systemctl start petasan-file-sync

 

greetings marcel

you do not need to modify cluster_info.json unless you are changing interface or bonds which applies to all nodes, but just changing the ip of a node it is not needed.

You will however need to change the node_info.json local file (as you showed), as well as in consul, as below example to change a node NODE01

consul kv get PetaSAN/Nodes/NODE01 > x
nano x # edit management ip
consul kv put PetaSAN/Nodes/NODE01 @x

hi i have edit the
/opt/petasan/config/node_info.json
adapted and also
consul kv get PetaSAN / Nodes / NODE01> x
nano x # edit management ip
consul kv put PetaSAN / Nodes / NODE01 @x

but the webgui time after the login
"Internal Server Error
The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application. "

what did i do wrong? :(

Apologies i did not see this..

i see you have address already in use errors..did you reboot the node after changing ips and still get this error..or you want to avoid reboots ?

can you ssh using the new ip ? is everything running ok apart from web ui ?

you only changed the management ip correct or did you also change backend ip ?
