NAME

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

SYNOPSIS

9       era_dump [options] {device|file}
10
11

DESCRIPTION

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

OPTIONS

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

41       Dumps era metadata on logical volume /dev/vg/metadata to standard  out‐
