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.
