xfs_mdrestore(8)                       System Manager's Manual                      xfs_mdrestore(8)

NAME
       xfs_mdrestore - restores an XFS metadump image to a filesystem image

SYNOPSIS
       xfs_mdrestore [ -gi ] [ -l logdev ] source target
       xfs_mdrestore -i [ -l logdev ] 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 display‐
              ing 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.

       -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.
