patch to add support for mdadm

This patch adds support for mdadm
Comment 3 Jan Synacek 2012-12-05 05:44:03 EST
The patch is 4 years old and seems that it has never been accepted upstream. It looks pretty ok-ish to me (not the shell calls though).
Comment 4 jcpunk 2012-12-06 11:52:43 EST
A few years back the mdadm folks said to only use mdadm to query the status.  Their current docs don't say that, so I'll whip something up in pure perl....

Will take a bit though.

pure perl scrape of /proc/mdstat

This patch makes no system calls.

For this to work under selinux, logwatch will need read access to system_u:object_r:proc_mdstat_t in order to read /proc/mdstat

That patch didn't run right on one of my hosts over the weekend.

I'll have a fixed one once I get it sorted.

Less error prone pure perl scrape of /proc/mdstat

This version runs fine on my systems.  Selinux still needs to grant getattr and read access to /proc/mdstat but this patch wont error out if the access is denied.

FYI mdadm script has been recently added to the mainstream repository:
