thin_restore(8) System Manager's Manual thin_restore(8)
NAME
thin_restore - restore thin provisioning metadata file to device or
file.
SYNOPSIS
thin_restore [options] -i {xml file} -o {device|file}
DESCRIPTION
thin_restore restores thin provisioning metadata created by the respec-
tive device-mapper target dumped into an XML formatted (see
thin_dump(8)) file, which optionally can be preprocessed before the re-
store to another device or file. If restored to a metadata device, the
metadata can be processed by the device-mapper target.
This tool cannot be run on live metadata.
OPTIONS
-h, --help
Print help and exit.
-V, --version
Print version information and exit.
-q, --quiet
Suppress output messages, return only exit code.
-i, --input {xml file}
Input file containing XML metadata.
-o, --output {device|file}
Output file or device for restored binary metadata.
If a file is used for output, then it must be preallocated, and large
enough to hold the metadata.
--transaction-id {natural}
Override the transaction id given in the input xml.
--data-block-size {natural}
Override the data block size given in the input xml.
--nr-data-blocks {natural}
Override the nr data blocks given in the input xml.
EXAMPLE
Restores the XML formatted thin provisioning metadata on file metadata
to logical volume /dev/vg/metadata for further processing by the re-
spective device-mapper target:
$ thin_restore -i metadata -o /dev/vg/metadata
DIAGNOSTICS
thin_restore returns an exit code of 0 for success or 1 for error.
