could please someone explain the correct sequence to re-establish a
cluster
after one node has failed.
According to the docs, the right sequence would be (assuming we have
DBs
A and B:
start server A
start server B
CreateCluster source=A target=B serverList=A,B
--> machine of A fails and gets restartet
delete DB file(s) of A
start server A
CreateCluster source=B target=A serverList=A,B
-> and everythig is fine
HOWEVER: assuming I have multiple clients which come up and
terminate at unknown times, Each of them has the list A,B in its URL.
==> assuming one of these clients hits the time between the
second
start server A
and
CreateCluster source=B target=A serverList=A,B
This client will think it has a cluster connection but actually
has two connections to unsynchronized DBs - a situation that should
be prevented!
Thanks
