Hi, I enabled mail notification for OMV on a raspberry pi2 and I red about issue with RRDTool.
Stopping and restarting monitoring service I see this error
Error #0:exception 'OMV\ExecException' with message 'Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C; systemctl start 'rrdcached' 2>&1' with exit code '1': Job for rrdcached.service failed.
