Thomas Schoebel-Theuer 6755b8e4b8 marsadm: remove superfluous _get_former_primary() 
This cannot work in case of split brain.
Therefore, some primary must be designated always explicitly.

Thomas Schoebel-Theuer a26198d97e marsadm: wait for devices to {dis,}appear even on {prim,second}ary --force 2014-01-23 11:56:35 +01:00
Thomas Schoebel-Theuer 767bb03060 marsadm: allow overrides of "marsadm secondary" in disconnected clusters 
When the communication is down in partitioned clusters, the command
"marsadm seconodary" would normally use the current timestamp of
the command execution for the Lamport update protocol.

Make an exception for the case that a concurrent "marsadm primary"
was given somewhere else on a disconnected / partitioned node: let
the "primary" always win over a "secondary" command.

Thomas Schoebel-Theuer c861a0d202 marsadm: disallow 'primary --force' in connected state 
DRBD does not allow to deliberately provoke a SPLIT BRAIN
in connected state.

Thus MARS Light cannot be required to support such silly things
in any way.

Thomas Schoebel-Theuer 216ecbffde marsadm: prevent mutual overwrite of delete symlinks 
Add an (unused) host context. Previously, concurrent
log-delete operations triggered by cron could lead to
unnecessary loss of deletetion symlinks.
