You need to perform a clean upgrade of an indexer in a cluster. You place the indexer into maintenance mode. What happens to the replication and search factor during this time?
Trap 1: The Master initiates bucket re-replication immediately
This is exactly what maintenance mode is designed to prevent.
Trap 2: The search factor is lowered to zero
The search factor remains defined, but the Master stops enforcing it for that node.
Trap 3: Search queries are routed to other peers
Search queries are managed by the search head, and maintenance mode does not automatically force all traffic elsewhere; it just stops reporting errors for the node.
- A
Bucket fix-up activities are suspended for this peer
Maintenance mode ignores the offline status of the peer for fix-up purposes.
- B
The Master initiates bucket re-replication immediately
Why wrong: This is exactly what maintenance mode is designed to prevent.
- C
The search factor is lowered to zero
Why wrong: The search factor remains defined, but the Master stops enforcing it for that node.
- D
Search queries are routed to other peers
Why wrong: Search queries are managed by the search head, and maintenance mode does not automatically force all traffic elsewhere; it just stops reporting errors for the node.
