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
