This commits enables the DRBD data collector to use the Confd client to gather information about the pairing between DRBD minors and instances. For testing purposes, the DRBD data collector now requires either zero or two parameters: one is the DRBD file, one is the pairings file. When no parameter is passed, the collector is in "production mode" and takes the data from /proc/drbd and from the Confd client. The shell tests of mon-collector are updated accordingly.

mon-collector(7) Ganeti | Version @GANETI_VERSION@
NAME
mon-collector - Command line interface for the data collectors of the monitoring system
SYNOPSIS
mon-collector {collector}
DESCRIPTION
mon-collector is a suite of tools designed to provide a command line
interface to the data collectors implemented by the ganeti monitoring system.
mon-collector is also the generic binary that must be invoked specifying,
as the first command line parameter, the name of the actual desired data
collector to be run.
When executed, mon-collector will run the specified collector and will
print its output to stdout, in JSON format.
COLLECTORS
DRBD
Collects the information about the version and status of the DRBD kernel module, and of the disks it is managing.
If status-file and pairing-file are specified, the status and the instance-minor paring information will be read from those files. Otherwise, the collector will read them, respectively, from /proc/drbd and from the Confd server.
The options that can be passed to the DRBD collector are as follows:
- -s status-file, --drbd-status=*status-file*
- Read the DRBD status from the specified file instead of /proc/drbd.
- -p pairing-file, --drbd-pairing=*pairing-file*
- Read the information about the pairing between instances and DRBD minors from the specified file instead of asking the Confd servers for them.
