Looks like Masterwishx's update for CA Mover Tuning has fixed the issue. I updated and tested it and it no longer breaks Disk Location. Thanks for the quick fix, @Masterwishx !

After some days running both plugins the problem hasn't occured again. Pretty safe to say that the issue is fixed.

Hi, I have been having an issue recently where none of my Unraid HDDs will sleep anymore, adding ~25W of power draw at all times.

I've been trying to monitor what is causing this and after disabling all Dockers, I've traced it back at least partially to the Disk Location plugin. I am using a small one-line script to trace PIDs and PPIDs after lsof -r 1 /dev/sd<xx> sees some disk activity. Here is an example trace back to a Disk Location cron job.

I've tried manually editing /etc/cron.d/root to change the frequency of syslog reads and smartctl status commands, but the plugin seems to auto-revert these back to every 5 minutes... */5 * * * *
Can we pretty please add something in the plugin configuration to change the frequency of these jobs so my disks can sleep?
I appreciate any input or if anybody has found a workaround. Otherwise I may need to just remove the plugin.

That cronjob (*/5) just looks at the syslog for devices when Unraid has read the SMART data, then Disk Location uses that info to read the SMART data as well within 5 minutes as the drives are already spinning.

Otherwise it does never read SMART from devices in STANDBY mode.

@motoxnate

To debug this further, you can always uninstall the plugin and see if it helps. Your config will remain.

Also make sure you're not using "turbo write", because that will spin all the drives during write.

Hello,

When I click the Locate button, the Green Activity LED light starts flashing, but the Blue Locate LED light does not respond.

1. The indicator signal definition for the hard drive backplane in my chassis complies with the SFF-8489 specification and the SGPIO specification.

   

2. I am using an LSI 3008 HBA card.

3. storcli command

   Many RAID or HBA adapters, like those that use the storcli (megaraid) management utility have the ability to control identification LEDs.

   eg. LSI / Broadcom adapters

   I successfully managed to light up the Blue Locate LED using the following commands.

   storcli /cx[/ex]/sx start locate

   1. First, identify the device identifier (e.g., /dev/sdb) of the hard drive that needs to be located in the system, then use the smartctl tool to obtain its unique serial number.

      smartctl -a /dev/sdX | grep -i 'Serial number'

   2. Use the storcli command to find the specific physical location of this hard drive on the RAID or HBA card, namely the Controller, Enclosure (optional), and Slot numbers.

      storcli /call/eall/sall show all | grep -B5 -i "your serial number"

   3. Turn on the Blue Locate LED

      storcli /cx[/ex]/sx start locate

      (here are my 2nd hard drive)

      storcli /c0/s2 start locate

   4. Turn off the Blue Locate LED

      storcli /c0/s2 stop locate

   It works well !

4. The following command might also work, but I haven't tested it yet. (General method, especially suitable for simple storage environments without a RAID card or HBA card.)

   ledctl locate=/dev/sdX

Finally, I would like to suggest if it's possible to add an option in the settings to choose the command used by the Locate button? Or to customize the command executed by the Locate button?

Thank you. Thanks a lot.

The locate button is only looping a SMART request and will only activate the activity LED. It doesn't always work, depending on the drive and manufacturer etc.

"storcli" isn't installed by default in Unraid, and I don't want to include that in the plugin. If it's installable via a plugin, then that's great, but I can't test the functionality myself as I don't have the hardware to test this. Maybe in the future I can add something.

What I need to know is the actual output of:
storcli /call/eall/sall show all | grep -B5 -i "your serial number"

If the output can be in JSON, that's even better.

I also need to know how to detect if /ex part is required or not, if ever.

storcli /cx[/ex]/sx start locate

I understand the "/c0/s2" - but what is /e[x]?

The ledctl would be straight forward to add as an option, as it uses only default drive paths, but which package is that in? I can't test it myself, but seems easy enough.

Hello,

I am trying to configure and visualize Array as 1 column and 6 rows. I need to assign it from the bottom. But if I choose in Tray assigment count direction option "left / bottom" and then I want to assign trays I see only 2 trays available. With option "left / top" I see all 6 trays. I guess it is some small bug ?

@FlamongOle Happy New Year. I have noticed a bug in the last few versions of the app, my apologies for not posting this sooner. There is an interesting bug involving drive read writes. It appears that the first Data drive (disk 1) pulls the Read/Written data from the last NVME drive. Only Data Disk1 is affected, please see the screenshots below. This bug is also present in the on-hover of the dashboard version of the plugin. The bug is present in Unraid versions 7.1.4 - 7.2.3. Let me know if you need anything else. Thank you.

I dunno when I will have time to look at this, but please send me a debug file. Thanks!

Can you try "right/bottom"? I wonder if the "left/top" has a weird bug for 1 column, but works for 2 or something (can't be bothered testing it again). But "right/bottom" should do the same for your setup, but runs the calculation slightly different. Please report back if it solves it. Otherwise, I will look at it when I find time and motivation.

Hello, thanks for a feedback. I can confirm that option "right / bottom" solved it.

Hello all,

I'm new to Unraid and I just loaded this app to my server to find and mark down what drives I have. The server I got has two drives in one tray. When I try to add all the drives to the app, they just swap out with one another and do not add both drives to one tray. I hope this makes sense.

Am I missing something? I'd like to have where I can see what two drives are in each tray. I have a 6x4 with 48 drives.

Thank you

You can't add more than one drive per assigned slot. Rather add multiple slots if you do dual drives per slot.

Okay, when you say add multiple slots, what do you mean exactly? Thank you for your reply!

You must add 6x8 or 12x4 depending on the layout you want. No ways to assign two drives into same number/slot.

Oh I see, thank you.

Is there a way to have the disk number in the disk location overview instead of the tray numbers?

So instead of

1 2 3 4 5

disk1 disk14 disk2 disk5

No, visible via mouseover if configured so

LOL...I never tried that. Thanks...

Love this solution. I'm looking at combining my 2 SSD's into 1 HDD drive bay and I was wondering if there is a way to 'split' the bay. Or what another option would be that would appear properly. I was also thinking of putting 2 rows (instead of 1) and then 'skipping' all the bottom ones on the actual HDD but I wasn't sure what it would do / look like - even with hide empty enabled. Ideas?

No ways to split the "bay", I see no reason for it either. Don't think of this to directly copy the looks of your server, rather where you find the disks. 2 HDD's in one bay: create 2 bays instead of just 1.

Easy to try different configurations, just create a new group and play with it until you're satisfied, no need to change the one you have until you find the one that fits your purpose.

I hope it makes sense enough :P

I'm getting an error "Could not save the configuration". I'm also confused why my tray picker lets me choose from 0 - 4 when I want to be able to set 1 - 5.
TIA for any hints or help.

Hello,
I would like to request a feature. I have multiple unraid servers, and when I change a disk on one server, often, I put the old in another server. I would like to not have to write again all warranty and comments info.
could we have en export import disk option?
thanks

Not much I can do with that info. Have you adjusted the start count to be "1" and not "0"? If it can't save, there's something conflicting, like trying to assign 5 if it doesn't exists but in your case could be 4. I don't have your config, so can't test.

Ye, that should be doable I guess. But it's not a priority right now. The dates can be copied from Unraid itself as this plugin doesn't store most of that data anymore.

Check out this file: /boot/config/disk.log
