Disks spin down, but get up by SMART readings

Featured Replies

Hi there! I'm facing a strange problem - I've seen a number of similar threads, but none seems to fit.

I reworked my unraid box, moving taking out a SATA SSD and the HBA, plugging in an NVME as cache, and other disks on the mobo connectors.
Since then, disks spin down, but always get up by a SMART reading:
 

May 14 15:54:20 Tower apcupsd[8958]: Communications with UPS lost.

May 14 16:34:11 Tower emhttpd: spinning down /dev/sdc
May 14 16:34:13 Tower emhttpd: read SMART /dev/sdc

As you can see, I still have to connect again the UPS USB cable :)
 


I've tried almost anything: disks are idling, dockers (I have a number!) and VMs are set off. Running 6.12rc5.
What could I try?

smart read  is because Unraid has detected IO on a drive and it is used to get temp etc. and not the cause of the spin up.

 

Have you tried safe mode to see if a plugin is the cause of the spin up?

Hi Simon! Yes, I did, but it keeps doing so. Disks spin down individually, but after some time are woken up.
Before that hardware rework (tried to save some power) it was working like a charm...

Looks like some of appdata is on disk3 is that expected? I know you said docker is shutoff at present so should be read.

 

appdata                           shareUseCache="only"    # Share exists on cache, disk3

 

Any remote systems reading drives?

 

maybe try removing cache dir plugin?

Geez, didn't notice that folder. It's empty fortunately, I'm removing it .. now!

I shut down the autofan too - removing the cache dir plugin, I'll report back soon.


( thanks for your prompt replies!)

Sob, I decided for another run in safe mode and... last shutdown, even it was clear, triggered a parity check. I'm goint to let it finish. 

The SMART message you get is simply something that happens when they spin up, and unrelated.

 

I had a similar issue and it was the ZFS Master Plugin and only affected my ZFS formatted disks.

So it's an effect, and not  a cause... mmm... 

In the while, Parity check finished in safe mode, but... same issue, even in safe mode. I'm stopping the server to prevent a spinning recycle.

During the night (...) I'll try to put back the HBA in, even I'd spare gladly those 10Watts (it's a 9211-8i flashed in IT mode).

small update: no news... :(

Spin down doesn't work correctly in maintenance mode, don't know why but it doesn't, try instead to start in normal mode and disable VM ad docker services.

 Yet done, it was my first try! :/

 

I'm noticing that the wake order is always the same: sdf, sdd, sdg, sdc, sdh

Upgraded to RC6, but unluckiliy no free solution... :| :D

 

I think I've messed up something. How can I "reset" my system and star new? I can save my appdata, but what about the array?


Thanks all!

Uh, it looks like I found the waking process!

It seems it's been an rclone job, launched by Custom scripts. It looks like it was looping on retrying... :/
Anyway, I put up the HBA and some spare HDDs. Long live the H97! :)
