Hi.

I had issues with couple of nodes which led to them being down, unable to be removed and replaced.

SELECT * FROM system.topology_requests WHERE done = False ALLOW FILTERING ;

 id           | done  | end_time | error | initiating_host | request_type | start_time
--------------+-------+----------+-------+-----------------+--------------+-----------
 cd9b84c0-... | False |     null |  null | 59853b48-...    |      replace |       null
 524e7f0c-... | False |     null |  null | a48691bf-...    |       remove |       null
 8a5185e6-... | False |     null |  null | a48691bf-...    |       remove |       null
 acc4f340-... | False |     null |  null | 094374c3-...    |      replace |       null

I don’t have exact steps that led to this, one of them ran out of disk space and I’ve tried to replace it with the other.

As I understand they are blocking other cluster ops, and removing records from topology_requests table will not help.

How can i remove/cancel stuck topology requests?

Also I have ks with tablets enabled, so no manual recovery.
