ltdbtool: manipulate CTDB's local TDB files
NAME
ltdbtool - manipulate CTDB's local TDB files
SYNOPSIS
- ltdbtool [OPTION...] {COMMAND} [COMMAND-ARGS]
DESCRIPTION
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
