LTDBTOOL(1) CTDB - clustered TDB database LTDBTOOL(1)

NAME

ltdbtool - manipulate CTDB's local TDB files

SYNOPSIS

ltdbtool [OPTION...] {COMMAND} [COMMAND-ARGS]

DESCRIPTION

ltdbtool is a utility to manipulate CTDB's local TDB databases (LTDBs) without connecting to a CTDB daemon.

It can be used to:

•dump the contents of a LTDB, optionally printing the CTDB record header information,

•convert between an LTDB and a non-clustered tdb by adding or removing CTDB headers and

•convert between 64 and 32 bit LTDBs where the CTDB record headers differ by 4 bytes of padding.

OPTIONS

-e

Dump empty records. These are normally excluded.

-p

Dump with header information, similar to "ctdb catdb".

-s {0 | 32 | 64}

Specify how to determine the CTDB record header size for the input database:

0

no CTDB header

32

CTDB header size of a 32 bit system (20 bytes)

64

CTDB header size of a 64 bit system (24 bytes)

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

-o {0 | 32 | 64}

Specify how to determine the CTDB record header size for the output database, see -s.

-S SIZE

Explicitly specify the CTDB record header SIZE of the input database in bytes.

-O SIZE

Explicitly specify the CTDB record header SIZE for the output database in bytes.

-h

Print help text.

COMMANDS

help

Print help text.

dump IDB

Dump the contents of an LTDB input file IDB to standard output in a human-readable format.

convert IDB ODB

Copy an LTDB input file IDB to output file ODB, optionally adding or removing CTDB headers.

EXAMPLES

Print a local tdb in "tdbdump" style:



      ltdbtool dump idmap2.tdb.0

Print a local tdb with header information similar to "ctdb catdb":



      ltdbtool dump -p idmap2.tdb.0

Strip the CTDB headers from records:



      ltdbtool convert -o0 idmap2.tdb.0 idmap.tdb

Strip 64 bit CTDB headers from records, running on i386:



      ltdbtool convert -s64 -o0 idmap2.tdb.0 idmap.tdb

Strip the CTDB headers from records by piping through tdbrestore:



      ltdbtool dump idmap2.tdb.0 | tdbrestore idmap.tdb

Convert a local tdb from a 64 bit system for usage on a 32 bit system:



      ltdbtool convert -s64 -o32 idmap2.tdb.0 idmap2.tdb.1

Add a default header:



      ltdbtool convert -s0 idmap.tdb idmap2.tdb.0
