Explanation The module dm-snapshot was not loaded at the time when FSE backup tried to create
volume snapshots.
Workaround You need to load the module and configure its automatic loading at subsequent system
startups.
To load the module, invoke the following command:
# modprobe dm-snapshot
To configure automatic loading of the module at subsequent system startups, add the string
dm-snapshot to the variable MODULES_LOADED_ON_BOOT in the file
/etc/sysconfig/kernel, like shown in the following example:
## Type: string
## ServiceRestart: boot.loadmodules
#
# This variable contains the list of modules to be loaded
# once the main filesystem is active
#
MODULES_LOADED_ON_BOOT="dm-snapshot"
