NAME

   xfs_mdrestore - restores an XFS metadump image to a filesystem image

SYNOPSIS

   xfs_mdrestore [ -gi ] [ -l logdev ] [ -r rtdev ] source target
   xfs_mdrestore -i [ -l logdev ] [ -r rtdev ] source
   xfs_mdrestore -V

DESCRIPTION

   xfs_mdrestore is a debugging tool that restores a metadata image generated by xfs_metadump(8) to a filesystem. The source argument specifies the location of the metadump image and the
   target  argument specifies the destination for the filesystem image.  If the source is -, then the metadata image is read from stdin. This allows the output of be another program such
   as a compression application to be redirected to xfs_mdrestore.  The target can be either a file or a device.

   xfs_mdrestore should not be used to restore metadata onto an existing filesystem unless you are completely certain the target can be destroyed.

OPTIONS

   -g     Shows restore progress on stdout.

   -i     Shows metadump information on stdout.  If no target is specified, exits after displaying information.  Older metadumps man not include any descriptive information.

   -l logdev
          Metadump in v2 format can contain metadata dumped from an external log.  In such a scenario, the user has to provide a device to which the log device contents from the metadump
          file are copied.

   -r rtdev
          Restore realtime device metadata to this device.  This is only required for a metadump in v2 format.

   -V     Prints the version number and exits.

DIAGNOSTICS

   xfs_mdrestore returns an exit code of 0 if all the metadata is successfully restored or 1 if an error occurs.
