Neha Pawar · Answer

kinda new It s not in any release but has been on master for a few weeks

Pradeep · Answer

ah that endpoint doesn t work for me is there any other workaround

Pradeep · Answer

how about if I disable the server and then rebalance would rebalance work

Neha Pawar · Answer

no it has to be untagged

Neha Pawar · Answer

there is another PUT API on the instance Butthat is a little buggy Trying to get an example for you

Pradeep · Answer

cool cool thanks

Pradeep · Answer

otherwise just updating the controller would be good

Pradeep · Answer

as in pulling the latest code

Pradeep · Answer

that s the worst case

Neha Pawar · Answer

if you re comfortable you can directly edit the tags in Zooinspector Cluster CONFIGS PARTICIPANTS Servernode

Neha Pawar · Answer

yes pulling latest code will have the API

Pradeep · Answer

just change to TAG LIST rite

Pradeep · Answer

or change the tag to untagged SERVER

Pradeep · Answer

Maybe updating with latest code is the better option I will go with that

Pradeep · Answer

Thanks a lot

Neha Pawar · Answer

both of your options will work

Neha Pawar · Answer

or untagged OFFLINE

Neha Pawar · Answer

```curl X PUT <http localhost 9000 instances Server 10 1 10 51 7000> H accept application json H Content Type application json d host 10 1 10 51 port 7000 type SERVER tags newName OFFLINE DefaultTenant REALTIME ``` this is the other API i was talking about

Pradeep · Answer

ah yeah I see this one

Neha Pawar · Answer

if you decide to use this one please note that the output of GET doesn t match input of PUT thats the bug The input i ve used here is slightly different

Pradeep · Answer

oh got it letme try this and see

Pradeep · Answer

just to double confirm server I am untagging is a realtime server so it would be still untagged OFFLINE

Pradeep · Answer

I could set it to too but just wondering

Neha Pawar · Answer

you can use untagged OFFLINE or untagged REALTIME or either way is fine

Neha Pawar · Answer

that s more for cluster management knowing what you had assigned that server for realtime of offline even after untagging

Pradeep · Answer

got it thanks trying it now
