Subject: [PATCH 167/169] glusterd/shd: Optimize the glustershd manager to send
|
|
|
50dc83 |
reconfigure
|
|
|
50dc83 |
|
|
|
50dc83 |
Traditionally all svc manager will execute process stop and then
|
|
|
50dc83 |
followed by start each time when they called. But that is not
|
|
|
50dc83 |
required by shd, because the attach request implemented in the shd
|
|
|
50dc83 |
multiplex has the intelligence to check whether a detach is required
|
|
|
50dc83 |
prior to attaching the graph. So there is no need to send an explicit
|
|
|
50dc83 |
detach request if we are sure that the next call is an attach request
|
|
