2 ltdbtool is a utility to manipulate CTDB's local TDB databases
3 (LTDBs) without connecting to a CTDB daemon.
4 </p><p>
5 It can be used to:
6 </p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><p>
7 dump the contents of a LTDB, optionally printing the CTDB
8 record header information,
9 </p></li><li class="listitem"><p>
10 convert between an LTDB and a non-clustered tdb
11 by adding or removing CTDB headers and
12 </p></li><li class="listitem"><p>convert between 64 and 32 bit LTDBs where the CTDB record
13 headers differ by 4 bytes of padding.

51 Print a local tdb in "tdbdump" style:
52 </p><pre class="screen">
53 ltdbtool dump idmap2.tdb.0
54 </pre><p>
55 Print a local tdb with header information similar to "ctdb catdb":
56 </p><pre class="screen">
57 ltdbtool dump -p idmap2.tdb.0
58 </pre><p>
59 Strip the CTDB headers from records:
60 </p><pre class="screen">
61 ltdbtool convert -o0 idmap2.tdb.0 idmap.tdb
62 </pre><p>
63 Strip 64 bit CTDB headers from records, running on i386:
64 </p><pre class="screen">
65 ltdbtool convert -s64 -o0 idmap2.tdb.0 idmap.tdb
66 </pre><p>
67 Strip the CTDB headers from records by piping through tdbrestore:
68 </p><pre class="screen">
69 ltdbtool dump idmap2.tdb.0 | tdbrestore idmap.tdb
70 </pre><p>
71 Convert a local tdb from a 64 bit system for usage on a 32 bit system:
72 </p><pre class="screen">
73 ltdbtool convert -s64 -o32 idmap2.tdb.0 idmap2.tdb.1
74 </pre><p>
75 Add a default header:
76 </p><pre class="screen">
77 ltdbtool convert -s0 idmap.tdb idmap2.tdb.0
78 </pre></div><div class="refsect1"><a name="idp49126576"></a><h2>SEE ALSO</h2><p>
