.TH ERA_DUMP 8 "Thin Provisioning Tools" "Red Hat, Inc." \" -*- nroff -*-
|
|
.SH NAME
|
|
era_dump \- dump era metadata from device or file to standard output
|
|
|
|
.SH SYNOPSIS
|
|
.B era_dump
|
|
.RB [options]
|
|
.I {device|file}
|
|
|
|
.SH DESCRIPTION
|
|
.B era_dump
|
|
dumps binary era metadata created by the device-mapper
|
|
era target on a
|
|
.I device
|
|
or
|
|
.I file
|
|
to standard output for
|
|
analysis or postprocessing in XML format.
|
|
XML formated metadata can be fed into era_restore (see
|
|
.BR era_restore(8) )
|
|
in order to put it back onto a metadata
|
|
.I device
|
|
(to process by the device-mapper target) or
|
|
.I file.
|
|
|
|
This tool cannot be run on live metadata.
|
|
|
|
.IP "\fB\-\-repair\fP".
|
|
Repair the metadata whilst dumping it.
|
|
|
|
.IP "\fB\-h, \-\-help\fP".
|
|
Print help and exit.
|
|
|
|
.IP "\fB\-V, \-\-version\fP".
|
|
Output version information and exit.
|
|
|
|
.IP "\fB\-\-logical\fP".
|
|
Fold any unprocessed write sets into the final era array. You
|
|
probably want to do this if you're intending to process the results as
|
|
it simplifies the XML.
|
|
|
|
.IP "\fB-o \fI{xml file}\fP"
|
|
Specify a file for the output rather than writing to stdout.
|
|
|
|
.SH EXAMPLES

|

|
|
to standard output in XML format:
|
|
.sp
|
|
.B era_dump /dev/vg/metadata
|
|
|
|
.SH DIAGNOSTICS
