xfs_mdrestore(8) System Manager's Manual xfs_mdrestore(8)
xfs_mdrestore - restores an XFS metadump image to a filesystem
image
xfs_mdrestore [ -gi ] [ -l logdev ] [ -r rtdev ] source target
xfs_mdrestore -i [ -l logdev ] [ -r rtdev ] 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.
-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.
xfs_mdrestore returns an exit code of 0 if all the metadata is
successfully restored or 1 if an error occurs.
