xfs_mdrestore(8)
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.
Diagnostics
xfs_mdrestore returns an exit code of 0 if all the metadata is successfully restored or 1 if an error
occurs.

xfs_mdrestore - restores an XFS metadump image to a filesystem image
Options
-g Shows restore progress on stdout.
-i Shows metadump information on stdout. If no target is specified, exits after displaying
