ltdbtool is a utility to cope with ctdb's local tdb copies (LTDBs)
without connecting to a ctdb daemon.
</p><p>It can be used to
</p><div class="itemizedlist"><ul class="itemizedlist" type="disc" compact><li class="listitem"><p>
dump the contents of a LTDB, optionally printing the ctdb
record header information,
</p></li><li class="listitem"><p>
convert between an LTDB and a non-clustered tdb
by adding or removing ctdb headers and
</p></li><li class="listitem"><p>convert between 64 and 32 bit LTDBs where the ctdb record
headers differ by 4 bytes of padding.
</p></li></ul></div><p>
</p></div><div class="refsect1" title="COMMANDS"><a name="id417114"></a><h2>COMMANDS</h2><div class="variablelist"><dl><dt><span class="term">help</span></dt><dd><p>

Dump the contents of a LTDB file to standard output in a
human-readable format.
</p></dd><dt><span class="term">convert <IDB> <ODB></span></dt><dd><p>
Make a copy of a LTDB optionally adding or removing ctdb headers.

The default is 32 or 64 depending on the system architecture.

Print a local tdb in "tdbdump" style:
</p><pre class="screen">
ltdbtool dump idmap2.tdb.0
</pre><p>
Print a local tdb with header information similar to "ctdb catdb":
</p><pre class="screen">
ltdbtool dump -p idmap2.tdb.0
</pre><p>
Strip the ctdb headers from records:
</p><pre class="screen">
ltdbtool convert -o0 idmap2.tdb.0 idmap.tdb
</pre><p>
Strip 64 bit ctdb headers from records, running on i386:
</p><pre class="screen">
ltdbtool convert -s64 -o0 idmap2.tdb.0 idmap.tdb
</pre><p>
Strip the ctdb headers from records by piping through tdbrestore:
</p><pre class="screen">
ltdbtool dump idmap2.tdb.0 | tdbrestore idmap.tdb
</pre><p>
Convert a local tdb from a 64 bit system for usage on a 32 bit system:
</p><pre class="screen">
ltdbtool convert -s64 -o32 idmap2.tdb.0 idmap2.tdb.1
</pre><p>
Add a default header:
</p><pre class="screen">
ltdbtool convert -s0 idmap.tdb idmap2.tdb.0
