| 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. |
