We don't use asite.conf, here's the contents of ourlocal.conf:# This file etc/rear/local.conf is intended for the user's # manual configuration of Relax-and-Recover (ReaR). # For configuration through packages and other automated means # we recommend a separated file named site.conf next to this file # and leave local.conf as is (ReaR upstream will never ship a site.conf). # The default OUTPUT=ISO creates the ReaR rescue medium as ISO image. # You need to specify your particular backup and restore method for your data # as the default BACKUP=REQUESTRESTORE does not really do that (see "man rear"). # Configuration variables are documented in /usr/share/rear/conf/default.conf # and the examples in /usr/share/rear/conf/examples/ can be used as templates. # ReaR reads the configuration files via the bash builtin command 'source' # so bash syntax like VARIABLE="value" (no spaces at '=') is mandatory. # Because 'source' executes the content as bash scripts you can run commands # within your configuration files, in particular commands to set different # configuration values depending on certain conditions as you need like # CONDITION_COMMAND && VARIABLE="special_value" || VARIABLE="usual_value" # but that means CONDITION_COMMAND gets always executed when 'rear' is run # so ensure nothing can go wrong if you run commands in configuration files.

Description of the issue (ideally so that others can reproduce it):
We initiated a backup of the system usingrear -v mkbackupwith the settings given above (NFS backup target). We created an LPAR with a smaller backing device (going from 100GB with 10GB used space to 20GB total), then booted from the backed up ISO and started the recover process:

Workaround, if any:
Manually editing the thecreate_disk_partitioncalls fixes the problem.

I did not yet look at the details here but in general
AUTORESIZE_PARTITIONS=true
is old functionality that is implemented in
layout/prepare/default/430_autoresize_all_partitions.sh
which does not and never did work properly.
See the description about
# AUTORESIZE_PARTITIONS
