ltdbtool1
Manipulate ctdb's local tdb files
Usage
ltdbtool [OPTION ...]
COMMAND
[COMMAND-ARGS]
Overview
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
