gnt-storage(8) Ganeti | Version @GANETI_VERSION@

================================================

Name

----

gnt-storage - Ganeti storage administration

Synopsis

--------

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

DESCRIPTION

-----------

The **gnt-storage** is used for managing the available storage inside

the Ganeti cluster. At the moment, it manages only external storage

(ExtStorage).

COMMANDS

--------

DIAGNOSE

~~~~~~~~

| **diagnose**

This command provides detailed information about the state of all

ExtStorage providers available in the Ganeti cluster. The state of each

provider is calculated per nodegroup. This means that a provider may be

valid (meaning usable) for some nodegroups, and invalid (not usable) for

some others. This command will help you see why an installed ExtStorage

provider is not valid for a specific nodegroup. It could be that it is

missing from a node, or is only partially installed. This command will

show the details of all ExtStorage providers and the reasons they are or

aren't valid for every nodegroup in the cluster.

INFO

~~~~

| **info**

| [*provider*]

This command will list detailed information about each ExtStorage

provider found in the cluster, including its nodegroup validity, the

supported parameters (if any) and their documentations, etc.

For each ExtStorage provider only the valid nodegroups will be listed.

If run with no arguments, it will display info for all ExtStorage

providers found in the cluster. If given ExtStorage provider's names as

arguments it will list info only for providers given.

NOTES

-----

In the future **gnt-storage** can be extended to also handle internal

storage (such as lvm, drbd, etc) and also provide diagnostics for them

too.

It can also be extended to handle internal and external storage pools,

if/when this kind of abstraction is implemented inside Ganeti.
