Woke up to a succesful parity check according to notification, but one of my parity disks have been disabled :-/

 

What would the best course of action be to resolve?

 

Thanks,

Please post the diagnostics: Tools - > Diagnostics

At work now, but will do when I return tonight.

 

Thanks :-)

Diagnostics here.

SMART for parity1 doesn't appear in diagnostics. Check connections and post another diagnostic.

Would that not be because the system disabled it?

No, it's because it dropped offline, a reboot or power/cycle should bring it back online, but it will remain disable (red x), just grab and post new diags.

Ok, updated diagnostics here.

SMART looks fine, you can resync parity on the old disk, I would recommend replacing or swapping the cables/backplane, just to rule them out in case the same disks fails again.

 

P.S. you might want to improve your disk cooling, disks should be kept under 40C, 45C tops, parity is the worst offender:

Lifetime    Min/Max Temperature:     23/60 Celsius

 

But there are more disks with a max temp over 50C.

 

 

 

 

 

 

Thanks :-)

 

Disks are on a cross flashed Dell H310 so I can only swap fwd breakout cable.

 

Since there are no errors on remaining 3 disks on same channel, can I safely rule out that it is not the HBA acting up?

 

Regarding cooling, I am actually trying to move disks around to decrease temps - the chassis is a Node 804 - so there is not hundreds of options.

 

Maybe I should get that custom chassis done...
