Description Sachin Punadikar 2025-10-06 07:26:07 UTC 
Description of problem:
With Ceph 9.0, haproxy config has new stanza added, "peers", which helps in maintaining in-memory stick-table across haproxy daemons.
When a node (on which Ganesha is running) goes down, cephadm starts Ganesha on another eligible node. This needs an update into the haproxy.cfg file.
On updating the config, haproxy daemon is restarted. This leads to loss of stick-table.
To maintain the in-memory stick-table persistent across config changes, haproxy should not be restarted, instead reload the config by sending SIGHUP

Version-Release number of selected component (if applicable):
