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.
