LTDBTOOL(1)LTDBTOOL(1)NAMEltdbtool - handle ctdb's local tdb copies
SYNOPSISltdbtool [OPTIONS] COMMAND
DESCRIPTIONltdbtool is a utility to cope with ctdb's local tdb copies (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.
COMMANDS
help
Print a help text.
dump <IDB>
Dump the contents of a LTDB file to standard output in a
human-readable format.
convert <IDB> <ODB>
Make a copy of a LTDB optionally adding or removing ctdb headers.
OPTIONS-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 a help text.
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
