diffindex-rred - Restricted restricted ed
diffindex-rred diff1 ...
diffindex-rred is a command line tool for applying diff --ed style patches, as used in APT's diff/Index format. It can efficiently apply
several patches in one run and does not need to read the whole source file into memory.
The source file is taken from stdin. The patched file is written to stdout. Compressed patch files are decompressed automatically if they
have the proper .gz, .bz2, or .lzo extension.
diffindex-rred is used by diffindex-download.

crm_diff - identify changes to the cluster configuration and apply patches to the configuration files
crm_diff [-?|-V] [-o filename] [-O string] [-p filename] [-n filename] [-N string]
The crm_diff command assists in creating and applying XML patches. This can be useful for visualizing the changes between two versions of
the cluster configuration or saving changes so they can be applied at a later time using cibadmin.
OPTIONS --help, -?
Print a help message.
--original filename, -o filename
Specify the original file against which to diff or apply patches.
--new filename, -n filename
Specify the name of the new file.
--original-string string, -O string
Specify the original string against which to diff or apply patches.
--new-string string, -N string
Specify the new string.
--patch filename, -p filename
Apply a patch to the original XML. Always use with -o.
Compare or patch the inputs as a CIB. Always specify the base version with -o and provide either the patch file or the second version
with -p or -n, respectively.
Read the inputs from stdin.
Use crm_diff to determine the differences between various CIB configuration files and to create patches. By means of patches, easily reuse
configuration parts without having to use the cibadmin command on every single one of them.
1. Obtain the two different configuration files by running cibadmin on the two cluster setups to compare:
cibadmin -Q > cib1.xml
cibadmin -Q > cib2.xml
2. Determine whether to diff the entire files against each other or compare just a subset of the configurations.
3. To print the difference between the files to stdout, use the following command:
crm_diff -o cib1.xml -n cib2.xml
4. To print the difference between the files to a file and create a patch, use the following command:
crm_diff -o cib1.xml -n cib2.xml > patch.xml
5. Apply the patch to the original file:
crm_diff -o cib1.xml -p patch.xml
/var/lib/heartbeat/crm/cib.xml--the CIB (minus status section) on disk. Editing this file directly is strongly discouraged.
