The options that can be passed to the program are as follows: |
| 203 | 203 |
|
| 204 |
--memory *mem* |
|
| 205 |
The memory size of the instances to be placed (defaults to |
|
| 206 |
4GiB). Units can be used (see below for more details). |
|
| 207 |
|
|
| 208 |
--disk *disk* |
|
| 209 |
The disk size of the instances to be placed (defaults to |
|
| 210 |
100GiB). Units can be used. |
|
| 211 |
|
|
| 212 | 204 |
--disk-template *template* |
| 213 | 205 |
The disk template for the instance; one of the Ganeti disk templates |
| 214 | 206 |
(e.g. plain, drbd, so on) should be passed in. |
| 215 | 207 |
|
| 216 |
--vcpus *vcpus* |
|
| 217 |
The number of VCPUs of the instances to be placed (defaults to 1). |
|
| 218 |
|
|
| 219 | 208 |
--max-cpu=*cpu-ratio* |
| 220 | 209 |
The maximum virtual to physical cpu ratio, as a floating point number |
| 221 | 210 |
greater than or equal to one. For example, specifying *cpu-ratio* as |
| ... | ... | |
| 284 | 273 |
overriding the cluster data with a simulated cluster. For details |
| 285 | 274 |
about the description, see the man page **htools**(1). |
| 286 | 275 |
|
| 287 |
--tiered-alloc *spec* |
|
| 288 |
Besides the standard, fixed-size allocation, also do a tiered |
|
| 289 |
allocation scheme where the algorithm starts from the given |
|
| 290 |
specification and allocates until there is no more space; then it |
|
| 291 |
decreases the specification and tries the allocation again. The |
|
| 292 |
decrease is done on the matric that last failed during |
|
| 293 |
allocation. The specification given is similar to the *--simulate* |
|
| 294 |
option and it holds: |
|
| 276 |
--standard-alloc *disk,ram,cpu* |
|
| 277 |
This option specifies the instance size for the *standard* allocation |
|
| 278 |
mode, where we simply allocate instances of the same, fixed size until |
|
| 279 |
the cluster runs out of space. |
|
| 280 |
|
|
| 281 |
The specification given is similar to the *--simulate* option and it |
|
| 282 |
holds: |
|
| 295 | 283 |
|
| 296 | 284 |
- the disk size of the instance (units can be used) |
| 297 | 285 |
- the memory size of the instance (units can be used) |
| 298 | 286 |
- the vcpu count for the insance |
| 299 | 287 |
|

An example description would be *100G,4g,2* describing an initial |
|
| 301 |
starting specification of 100GB of disk space, 4GiB of memory and 2 |
|
| 302 |
VCPUs. |
|
| 288 |
An example description would be *100G,4g,2* describing an instance |
|
| 289 |
specification of 100GB of disk space, 4GiB of memory and 2 VCPUs. |
|

|
| 291 |
--tiered-alloc *disk,ram,cpu* |
|
| 292 |
Besides the standard, fixed-size allocation, also do a tiered |
|
| 293 |
allocation scheme where the algorithm starts from the given |
|
| 294 |
specification and allocates until there is no more space; then it |
|
| 295 |
decreases the specification and tries the allocation again. The |
|
| 296 |
decrease is done on the metric that last failed during allocation. The |
|
| 297 |
argument should have the same format as for ``-standard-alloc``. |
|
| 303 | 298 |
|
| 304 | 299 |
Also note that the normal allocation and the tiered allocation are |
| 305 | 300 |
independent, and both start from the initial cluster state; as such, |
