[Pkg-nagios-devel] Bug#742943: check_raid: wants mpt-statusd / mptctl

[Daniel Pocock]

Package: nagios-plugins-contrib
Version: 4.20120702



I'm using check_raid for an md RAID (managed by mdadm)

However, I get errors if mptctl is not loaded:

# /usr/lib/nagios/plugins/check_raid
open /dev/mptctl: No such file or directory
  Try: mknod /dev/mptctl c 10 220
Make sure mptctl is loaded into the kernel
OK: md:[md0(raid1):UU]


The errors are on stderr, regular status info is on stdout

Loading mptctl manually makes the errors go away:

   # modprobe mptctl

but it would be nice if I didn't have to make any workaround like this.


If I don't have the mpt-statusd package on my system at all, check_raid
gives spurious warnings:

# /usr/lib/nagios/plugins/check_raid
OK: md:[md0(raid1):UU]mpt:mpt-status program not found



Apart from this spurious output, it does actually work correctly for my
md RAID and correctly detected a disk failure this week.

The system in question does have MPT hardware, but the hardware RAID
feature is not in use.
