xfs_mdrestore - restores an XFS metadump image to a filesystem image

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

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.

Shows restore progress on stdout.
Shows metadump information on stdout. If no target is specified, exits after displaying information. Older metadumps man not include any descriptive information.
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.
Prints the version number and exits.

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