<div dir="ltr">Hi all,
<div><br>
</div>
<div>I have a configuration which uses RAID meta-devices set up
as raid1 over empty slots for GUI configuration and
notification. As such, I have md0 and md1 showing up as fatal
errors in Xymon. Again, this setup is standard for this
installation. md2 + are all normal normal, valid (and
actually hold mounted filesystems).</div>
<div><br>
</div>
<div>I'd normally expect to be able to set up analysis.cfg to
"something something IGNORE" for this machine. Like:</div>
<div><br>
</div>
<div>HOST=<a href="http://vault.home.vollink.com" target="_blank">vault.home.vollink.com</a></div>
<div> RAID md0 IGNORE</div>
<div> RAID md1 IGNORE</div>
<div><br>
</div>
<div>Does such a thing exist (and I missed it/have the syntax
wrong?) If not, /could/ such a thing exist?</div>
<div><br>
</div>
<div>I'm starting to become used to just having a RED screen
(and that is dangerous).</div>
<div><br>
</div>
<div>If the answer to the above is all, 'no,' then what is the
best way to ignore all RAID for that machine?</div>
<div><br>
</div>
<div>Thank you much for any thoughts,</div>
<div>Gary</div>

<p>You will need to share a your /proc/mdstat and/or a pointer to
which ext script you are using to monitor your md RAID. I suspect
that your RAID arrays are defined as a two member RAID1 with one
missing member, therefore, they would be expected to show as red,
because they are failed.</p>
<p>You could either define the RAID arrays as RAID1 with only one
member, or else define them as RAID0 with only one member. <br>
</p>
<p>Or, you could add the spare drives as spares, or simply not
define them as RAID arrays until you actually need to use them.</p>

To be clear: "I don't know" is acceptable, I read through source-code looking for a way, and I couldn't find one (and so-many bits are auto-loaded that it's super hard to be sure enough to say "no"). I was hoping someone on-list would actually know, but I get why that might not be the case.</div><div><br></div><div>To the questions:</div><div><pre>============================ /proc/mdstat ===========================
