Error - Cluster operations in progress. Modifications temporarily suspended on Publisher node

Question Error - Cluster operations in progress. Modifications temporarily suspended on Publisher node.
Environment Publisher-Subscriber setup. we try to upgrade the code on servers to 6.2 and the subscriber gets stuck and fails to rejoin the cluster.
At this point, when we try to drop the subscriber from the publisher and it fails to drop.

 

At this point, when we try to drop the subscriber from the publisher, we will get the below error:
 
[appadmin@cppm]# cluster drop-subscriber -i 192.168.10.10 -f
ERROR - Removing entry from database failed
ERROR - Failed to notify publisher about subscriber deletion. Ignoring the error...
INFO - Attempting remote drop of the subscriber node...
ERROR - 192.168.10.10: - Ignore drop node request from unknown publisher
 
 
Solution:
 
To get your setup back into action, following are the steps in my view:
 
Login to Publisher UI and perform Drop subscriber (on designated standby whose cluster sync status = IN_PROGRESS).
- On Publisher, Drop subscriber will be refused, and an error will be prompted to disable Designated Standby configuration.
- Disable the Designated Standby settings using Cluster wide parameters.
- If subscriber node is part of VIP configuration, Drop subscriber will be refused again, and an error is prompted to disable/remove the corresponding VIP configuration. 
- After disabling the above, Drop subscriber completes successfully on Publisher
- Since cluster is out of sync, manually reset the database on Subscriber and perform Make subscriber on this node.
- Once the subscriber is added back to cluster, reconfigure the VIP and Designated standby configuration as before.

Hello, 

 

I have the same problem and I do not have "Designated Standby" configured. but still i get the same error.

 

ERROR - Removing entry from database failed
ERROR - Failed to notify publisher about subscriber deletion.
Ignoring the error...

INFO - Attempting remote drop of the subscriber node...
ERROR - 10.85.177.2: - Ignore drop node request from unknown publisher

 

 

Can anyone help me?

I had this error occur as well. 

I upgraded my publisher from 6.4 to 6.5 but hadn't yet restarted the appliance. After the upgrade any changes I tried making returned the error "Cluster operations in progress. Modifications temporarily suspended". This was odd because the appliance was a standalone publisher with no subscribers. However, it was a simple fix - restarted the appliance and had the publisher come up on 6.5 and I didnt see the error again.
