From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4.1) Gecko/20031114 Description of problem: /etc/rc.d/init.d/mdmonitor uses a hack to start mdadm. I found that mdadm can be started in the standard way, with daemon(), initlog etc. So I made a patch for the init script, which maybe will help if the errata for #112490 does not already have an improvement: daemon --check mdadm \ "/bin/bash -c \"mdadm --monitor --scan -f > /var/run/mdadm.pid\"" mdadm in monitor mode will run in background if argument -f or --daemonise is given. Although mdadm(8) man page says "Also write pid of mdadm daemon to /var/run/mdadm.", I did not see this happening. The man page also says and this is true: in daemon mode mdadm will write the pid of the daemon on stdout. With an extra shell invocation and a redirection I managed to write this pid to /var/run/mdadm.pid. One possible problem: if mdadm refuses to start or become a daemon, then /var/run/mdadm.pid will be created as a zero size file. If this is a problem, then the script could check the size and delete the file. Version-Release number of selected component (if applicable): mdadm-1.3.0-1 How reproducible: Always Steps to Reproduce: 1. Review /etc/rc.d/init.d/mdmonitor 2. service mdmonitor start and see the odd output format. 3. Additional info:

We will review this... remind me in 10 days if you don't hear anything from me.
Consider yourself reminded :-)
Took a quick look. The FC2 initscript changed a bit from FC1, but aside from that I am uncertain about the behavior of the kernel side enough to determine if removing the ugly sleep hack is safe or not. I would recommend raising this on f-d-l.
mdmonitor initscript is really the same in FC1 and FC2 test2, probably you looked at the new mdmpd initscript. The comment before the sleep says that it's there to give mdadm a chance to start and decide if it should die due to some errors or continue to run in monitor mode.
This should show up in the 1.5.0-4 version of the package.
