After I realized that we no longer make any node primary automatically :)
Here the suggestion of the new configure option:
disconnect No automatic resynchronisation gets performed. One
node should drop its net-conf (preferable the
node that would become sync-target)
I think this should be default.
ass-older Auto sync source is the oder primary (current default i.t.s.)
ass-younger Auto sync source is the younger primary
ass-furthest Auto sync source is the node that did more modifications
ass-NODENAME Auto sync source is the named node
Falls es schon einen pirmary gibt (also dieses:
P --- S Everything ok.
P - - S N1 is failing, but for the moment being just can no
longer answer the network; but it is still able to update
drbds generation counts
? - S Now N1 may be dead, or maybe not
X - S A sane Cluster-mgr makes N2 primary, but stonith N1 first ...
X - P N1 now is really dead.
S --- P N1 comes back
S - : P oops, N1 has "better" generation counts than N2
N2 shall become sync target, but since it is
currently Primary, it will refuse this.
It goes standalone.
disconnect (current behaviour in the situation.)
ass-* Auto sync, but the current primary gets sync-source.
What do you think ?
