** [tickets:#2705] ntf: ntfd remove client in standby node while not finalize
in active node**
**Status:** accepted
**Milestone:** 5.18.01
**Created:** Mon Nov 27, 2017 07:32 AM UTC by Canh Truong
**Last Updated:** Mon Nov 27, 2017 07:35 AM UTC
**Owner:** Canh Truong
Steps to reproduce the issue (not always happen):
1/ saNtfInitialize_1
2/ saNtfFinalize_1
3/ saNtfInitialize_2
4/ saNtfNotificationSubscribe_2
5/ saNtfFinalize_2
At the end of step 2, the NCSMDS_DOWN event will be send to both active and
standby node.
- In active node, mds thread send this request to ntfd through mailbox. ntfd
receive this request to process this event and it delete the all clients then
go to step 3 to: initialize new client_2 and send ckpt to standby to initialize
(create) new client_2 in standby node.
- In standby node, mds thread send this request to ntfd through mailbox. But
ntfd receive the NCSMDS_DOWN request after ckpt of initialize request of step
3. So new client_2 is created in standby node first, then ntfd process the
NCSMDS_DOWN request. It will remove all clients in standby node. No client in
standby node
In step 4, the subcribe request is processed in active node and send ckpt of
this request to standby node. In the standby node, ntfd receive the ckpt of
subcribe request and process. But it can not find the client
