All, I'm not sure if this is a config issue or bug. I have 2 servers with mdadm/mdraid arrays. In both a check of 'systemctl --type=service' shows mdmonitor has failed. It fails to start each time: ● mdmonitor.service - MD array monitor Loaded: loaded (/usr/lib/systemd/system/mdmonitor.service; static; vendor preset: disabled) Active: failed (Result: exit-code) since Sat 2015-08-22 22:33:52 CDT; 7h ago Process: 377 ExecStart=/sbin/mdadm --monitor $MDADM_MONITOR_ARGS (code=exited, status=1/FAILURE) Process: 375 ExecStartPre=/usr/lib/systemd/scripts/mdadm_env.sh (code=exited, status=203/EXEC) Main PID: 377 (code=exited, status=1/FAILURE) Looking at the service file I'm not sure if there is an issue here, or somewhere else, but there is no file 'mdadm_env.sh' that is reference by ExecStartPre=: # This file is part of mdadm. # <snip> [Unit] Description=MD array monitor DefaultDependencies=no [Service] Environment= MDADM_MONITOR_ARGS=--scan EnvironmentFile=-/run/sysconfig/mdadm ExecStartPre=-/usr/lib/systemd/scripts/mdadm_env.sh ExecStart=/sbin/mdadm --monitor $MDADM_MONITOR_ARGS Is this a bug? -- David C.
