- Collect data directly from the master daemon, which is to be
- contacted via the luxi (an internal Ganeti protocol). An optional
- *path* argument is interpreted as the path to the unix socket on
- which the master daemon listens; otherwise, the default path used by
- ganeti when installed with *--localstatedir=/var* is used.
-
---simulate *description*
- Instead of using actual data, build an empty cluster given a node
- description. The *description* parameter must be a comma-separated
- list of five elements, describing in order:
-
- - the allocation policy for this node group
- - the number of nodes in the cluster
- - the disk size of the nodes, in mebibytes
- - the memory size of the nodes, in mebibytes
- - the cpu core count for the nodes
-
- An example description would be **preferred,B20,102400,16384,4**
- describing a 20-node cluster where each node has 100GiB of disk
- space, 16GiB of memory and 4 CPU cores. Note that all nodes must
- have the same specs currently.
-
- This option can be given multiple times, and each new use defines a
- new node group. Hence different node groups can have different
- allocation policies and node count/specifications.
-
---tiered-alloc *spec*
- Besides the standard, fixed-size allocation, also do a tiered
- allocation scheme where the algorithm starts from the given
- specification and allocates until there is no more space; then it
- decreases the specification and tries the allocation again. The
- decrease is done on the matric that last failed during
- allocation. The specification given is similar to the *--simulate*
- option and it holds:
-
- - the disk size of the instance
- - the memory size of the instance
+ Backend specification: collect data directly from the master daemon,
+ which is to be contacted via LUXI (an internal Ganeti protocol). The
+ option is described in the man page **htools**(1).
+
+\--simulate *description*
+ Backend specification: similar to the **-t** option, this allows
+ overriding the cluster data with a simulated cluster. For details
+ about the description, see the man page **htools**(1).
+
+\--standard-alloc *disk,ram,cpu*
+ This option overrides the instance size read from the cluster for the
+ *standard* allocation mode, where we simply allocate instances of the
+ same, fixed size until the cluster runs out of space.
+
+ The specification given is similar to the *\--simulate* option and it
+ holds:
+
+ - the disk size of the instance (units can be used)
+ - the memory size of the instance (units can be used)
