NAME

6       era_dump - dump era metadata from device or file to standard output.
7

SYNOPSIS

9       era_dump [options] {device|file}
10

DESCRIPTION

12       era_dump  dumps  binary  era  metadata created by the device-mapper era
13       target on a device or file to standard output for analysis or  postpro‐
14       cessing   in  XML  format.  XML  formated  metadata  can  be  fed  into
15       era_restore (see era_restore(8)) in order to put it back onto  a  meta‐
16       data device (to process by the device-mapper target) or file.
17
18       This tool cannot be run on live metadata.
19

OPTIONS

21       -h, --help
22              Print help and exit.
23
24       -V, --version
25              Print version information and exit.
26
27       --repair
28              Repair the metadata whilst dumping it.
29
30       --logical
31              Fold any unprocessed write sets into the final era array.
32
33           You probably want to do this if you're intending to process the results as
34           it simplifies the XML.
35
36       -o  {xml  file}  Specify  a file for the output rather than writeing to
37       stdout.
38

40       Dumps era metadata on logical volume /dev/vg/metadata to standard  out‐
41       put in XML format:
