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,  includ‐
       ing 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.
