MD Softraid Service does not differentiate

…between a normal scheduled check and a (forced) resync/resilvering process.

Hey guys,

I have machines with Softraids (mdadm). According to /etc/cron.d/mdadm every sunday morning, the raid will check if everything is mirrored properly, by running some routine consistency checks.

The MD Softraid Service is not able to differentiate this and gives me a warning.
However, it can be clearly seen by running mdadm --detail /dev/mdX | grep State that the array is clean.

I suggest to check the line for clean (ok) or degraded (warn) and provide a patch for this service check.

Output of check plugin WARN - Status: active, Spare: 0, Failed: 0, Active: 2, Status: 2/2, UU, [Resync/Recovery] Finish: 251.5min, Speed: 51986K/secWARN

Also, it would be great if the percentage could also be shown.

As it seems, I was not the only one with this issue and there already is an attempt to fix it:
