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
