cache_check \- repair cache metadata on device or file
.SH SYNOPSIS
.B cache_check
.RB [ options ]
.I {device|file}
.SH DESCRIPTION
.B cache_check
checks cache metadata created by
the device-mapper cache target on a
.I device
or
.I file.
.SH OPTIONS
.IP "\fB\-q, \-\-quiet\fP"
Suppress output messages, return only exit code.
.IP "\fB\-h, \-\-help\fP"
Print help and exit.
.IP "\fB\-V, \-\-version\fP"
Output version information and exit.
.IP "\fB\-\-super\-block\-only\fP"
Only check the superblock is present.
.IP "\fB\-\-skip-mappings\fP"
Skip checking of the block mappings which make up the bulk of the
metadata.
.IP "\fB\-\-skip-hints\fP"
Skip checking of the policy hint values metadata.
.IP "\fB\-\-skip-discards\fP"
Skip checking of the discard bits in the metadata.
.SH EXAMPLE
Analyses and repairs cache metadata on logical volume
/dev/vg/metadata:
.sp
.B cache_check /dev/vg/metadata
The device may not be actively used by the target
when running.
.SH DIAGNOSTICS
.B cache_check
returns an exit code of 0 for success or 1 for error.

.TH CACHE_DUMP 8 "Thin Provisioning Tools" "Red Hat, Inc." \" -*- nroff -*-
.SH NAME
cache_dump \- dump cache metadata from device or file to standard output
.SH SYNOPSIS
.B cache_dump
.RB [options]
.I {device|file}
.SH DESCRIPTION
.B cache_dump
dumps binary cache metadata created by
the device-mapper cache 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 cache_restore (see
.BR cache_restore(8) )
in order to put it back onto a metadata
.I device
(to process by the device-mapper target) or
.I file.
.IP "\fB\-r, \-\-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.
.SH EXAMPLES
Dumps the cache metadata on logical volume /dev/vg/metadata
to standard output in XML format:
.sp
.B cache_dump /dev/vg/metadata
.SH EXAMPLES
Dumps the cache metadata on logical volume /dev/vg/metadata
whilst repairing it to standard output in XML format:
.sp
.B cache_dump --repair /dev/vg/metadata
.SH DIAGNOSTICS
.B cache_dump
returns an exit code of 0 for success or 1 for error.

.SH SYNOPSIS
.B cache_repair
.RB [ options ]
.RB -i
.I {device|file}
.RB -o
.I {device|file}
.SH DESCRIPTION
.B cache_repair
reads binary cache metadata created by the
respective device-mapper target from one
.I device
or
.I file
, repairs it and writes it to another
.I device
or
.I file.
If written to a metadata
.I device
, the metadata can be processed
by the device-mapper target.
.IP "\fB\-i, \-\-input\fP \fI{device|file}\fP"
Input file or device with binary metadata.
.IP "\fB\-o, \-\-output\fP \fI{device|file}\fP"
Output file or device for repaired binary metadata.
.IP "\fB\-h, \-\-help\fP"
Print help and exit.
.IP "\fB\-V, \-\-version\fP"
Output version information and exit.
.SH EXAMPLE
Reads the binary cache metadata from file
.B metadata
, repairs it and writes it to logical volume /dev/vg/metadata
for further processing by the respective device-mapper target:
.sp
.B cache_repair -i metadata -o /dev/vg/metadata

.SH DESCRIPTION
.B cache_restore
restores cache metadata created by the respective
device-mapper target dumped into an XML formatted (see
.BR cache_dump(8) )
.I file
, which optionally can be preprocessed before the restore to another
.I device
or
.I file.
If restored to a metadata
.I device
, the metadata can be processed by the device-mapper target.
.IP "\fB\-i, \-\-input\fP \fI{device|file}\fP"
Input file or device with metadata.
.IP "\fB\-o, \-\-output\fP \fI{device|file}\fP"
Output file or device.
.IP "\fB{\-\-debug-override-metadata-version}\fP \fI<integer>\fP"
ONLY FOR DEBUGGING PURPOSES:

override the version stored in the metadata.
.IP "\fB\-h, \-\-help\fP"
Print help and exit.
.IP "\fB\-V, \-\-version\fP"
Output version information and exit.
.SH EXAMPLE
Restores the XML formatted cache metadata on file
.B metadata
