gnt-debug(8)
NAME
gnt-debug - debug commands
SYNOPSIS
gnt-debug command [ arguments... ]
DESCRIPTION
The gnt-debug is used for debugging the ganeti system.
COMMANDS
- ALLOCATOR
- allocator [ --debug ] [ --dir DIRECTION ] --algorithm ALLOCATOR
[ --mode MODE ] [ --mem MEMORY ] [ --disks DISKS ] [ --disk-template
- TEMPLATE ] [ --nics NICS ] [ --os-type OS ] [ --vcpus VCPUS ] [ --tags TAGS ] instance
- Executes a test run of the iallocator framework.
- The command will build input for a given iallocator script (named with the --algorithm option), and either show this input data (if DIRECTION is in) or run the iallocator script and show its output (if DIRECTION is out).
- If the MODE is allocate, then an instance definition is built from the other arguments and sent to the script, otherwise (MODE is relocate) an existing instance name must be passed as the first argument.
- This build of ganeti will look for iallocator scripts in the following directories: /usr/local/lib/ganeti/iallocators,/usr/lib/ganeti/iallocators; for more details about this framework, see the HTML or PDF documentation.
- DELAY
- delay [ --debug ] [ --no-master ] [ -n NODE ... ] duration
- Run a test opcode (a sleep) on the master (internally in the command) and on selected nodes (via an RPC call). This server no other purpose but to execute a test operation.
- The -n option can be given multiple times to select the nodes for the RPC call. By default, the delay will also be executed on the master, unless the --no-master option is passed.
- The delay argument will be interpreted as a floating point number.
