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 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.
| −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.
