On a further examination, the problem will make a difference only if $vg is in the ${create_thin_volumes_only[@]} array and the LV is not thin. This would happen only with FORCE_VGCFGRESTORE=yes and with a VG that has a thin pool and also a non-thin LV. Also, MIGRATION_MODE must be off.
Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.

Description of problem: During restoration of a storage layout with LVM, this message appears in the log: /var/lib/rear/layout/diskrestore.sh: line <n>: <vg>: command not found where <vg> is a volume group name. This is because of this line in usr/share/rear/layout/prepare/GNU/Linux/110_include_lvm_code.sh if IsInArray $vg \"\${create_logical_volumes[@]}\" && ! \$IsInArray $vg \"\${create_thin_volumes_only[@]}\" ; then which after quote removal becomes this in disklayout.sh ... $IsInArray $vg "${create_thin_volumes_only[@]}" and this is equivalent to just $vg "${create_thin_volumes_only[@]}", because $IsInArray does not exist (IsInArray is a shell function, not a variable). The line should read just if IsInArray $vg \"\${create_logical_volumes[@]}\" && ! IsInArray $vg \"\${create_thin_volumes_only[@]}\" ; then This problem does not exist upstream, I probably backported an old version of the change in https://github.com/rear/rear/pull/2691. Version-Release number of selected component (if applicable): 2.6 How reproducible: for the message: recovery of a system with LVM, most likely it depends on migration mode being in use (MIGRATION_MODE=TRUE) Not sure what to do to trigger an actual problem, probably it involves a thin pool.
