Synopsis |

**gnt-storage** {command} [arguments...]

DESCRIPTION |
| 15 |
----------- |
| 16 |
|
| 17 |
The **gnt-storage** is used for managing the available storage inside |
| 18 |
the Ganeti cluster. At the moment, it manages only external storage |
| 19 |
(ExtStorage). |

COMMANDS |
| 22 |
-------- |
| 23 |
|

|
| 25 |
**diagnose** |
| 26 |
|
| 27 |
This command provides detailed information about the state of all |
| 28 |
ExtStorage providers available in the Ganeti cluster. The state of each |
| 29 |
provider is calculated per nodegroup. This means that a provider may be |
| 30 |
valid (meaning usable) for some nodegroups, and invalid (not usable) for |
| 31 |
some others. This command will help you see why an installed ExtStorage |
| 32 |
provider is not valid for a specific nodegroup. It could be that it is |
| 33 |
missing from a node, or is only partially installed. This command will |
| 34 |
show the details of all ExtStorage providers and the reasons they are or |
| 35 |
aren't valid for every nodegroup in the cluster. |
| 36 |
|
| 37 |
**info** |
| 38 |
|
| 39 |
This command will list detailed information about each ExtStorage |
| 40 |
provider found in the cluster, including its nodegroup validity, the |
| 41 |
supported parameters (if any) and their documentations, etc. |
| 42 |
|
| 43 |
For each ExtStorage provider only the valid nodegroups will be listed. |
| 44 |
|
| 45 |
If run with no arguments, it will display info for all ExtStorage |
| 46 |
providers found in the cluster. If given ExtStorage provider's names as |
| 47 |
arguments it will list info only for providers given. |
| 48 |

NOTES |
| 50 |
----- |
| 51 |
|
| 52 |
In the future **gnt-storage** can be extended to also handle internal |
| 53 |
storage (such as lvm, drbd, etc) and also provide diagnostics for them |
| 54 |
too. |
| 55 |
|
| 56 |
It can also be extended to handle internal and external storage pools, |
| 57 |
if/when this kind of abstraction is implemented to Ganeti. |
