Thanks again for taking a look. I rebuilt on top and then went through the entire process to add 2x12TB parity disks one at a time and then moved my old 2x10TB parity disks down to data disks. No errors.

Attached. Thanks tower-diagnostics-20240716-0903.zip

Today, I have 130 read errors on a different drive (19). This time it looks like Unraid has pulled the drive and it's now being emulated. Attached new Diagnostics.. please help. New drives should hopefully get here soon.tower-diagnostics-20240715-1936.zip

Thank you for taking the time to evaluate. I will pay attention to the attributes you highlighted.

No issues during the extended SMART test for Disk 17. SMART self-test history: Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error # 1 Extended offline Completed without error 00% 64998 - # 2 Short offline Completed without error 00% 64984 - The Smart Error Log item still shows "No Errors Logged". Still just the 128 read errors. Current diagnostics attached. Thanks again. tower-diagnostics-20240713-1617.zip

This morning I encountered 128 read errors with one of my drives (Disk 17, a 6TB WD Red). Nothing else seems to be amiss. I've been running without any issue for years in an enterprise chassis. I run a monthly parity check and it's been 6+ months since I've physically touched any of the hardware. There was nothing unusual about this morning (no one bumped the case, no power hiccups, etc). Would someone please take a look at my attached diagnostics and let me know if anything stands out? Disk 17 - SMART short-test completed without error, running long test now. (Side note, I have 2x 12TB drives on the way. The plan was to upgrade parity and move the 2x 10TB I have as parity now, to data drives. Hopefully I can still do that.) Thanks in advance tower-diagnostics-20240711-1511.zip

Same. Any ideas? I'm not sure why it happens, but it does not seem to impact my Plex server (that I've noticed)

I am interested in running two dual-parity protected arrays in a single chassis w/ Unraid on bare metal. I have a smaller array for testing and data that would be a minor headache to replace (6 data drives + 2 parity). I also have my "Production" Unraid array that houses my primary data that would be a huge issue if I lost (18 data drives and growing + 2 parity & full/daily offsite backup). My chassis is 36 bays and I currently run Unraid on top of ESXi, passing through the USB keys along with HBAs and NVMe cache drives to get as close to bare metal as I can. Edit: After ZFS lands, surely multiple Unraid parity arrays will be next…?

I'm having this issue as well... I have two Ubuntu 16.04 servers and they both will throw an error after a while on my most used folders. I have the mover enabled (FYI), but haven't tied any of this to it yet. This had not been a problem until recently. I guess I'll try to use 1.0 and see if it fixes it. Very frustrating.

Thanks for the app. I am trying to get my NUT stats to display. Am I missing them? iOS 13 ControlR v4.10.0 NUT Plug-in 02-03-19 unRaid 6.7.2 Do I need the ControlR plugin for NUT stats to work? Thanks

Wanted to chime in and say thanks! I had this happen to me tonight on version 6.3.5. Would be really nice to get an explanation on what might cause this from LT.

unRAID won't clear a new parity drive. There is no need for it to be clear since it will be completely overwritten by the parity sync. So if you want to test your new parity drive you may want to preclear it anyway. I meant I would be preclearing the OLD parity drive to be used as a new data drive in the array (like you discuss below). Thanks for this, I'll be sure to keep a link to it for the future.

FYI, since v6.2 clear is done with the array online, but disk is not tested like when using preclear. Thanks for that info too. I'll take advantage of that when I upgrade my parity drives again (and look to use them as data drives in the array). As a follow up to what you noted above, I proceeded with starting the array and unRAID picked up the preclear signature and prompted for only a quick format. Everything as you indicated. thx

That's normal, unRAID only checks for the preclear signature after starting the array. Many thanks Johnnie! Been quite a while since I expanded my array. Wanted to make sure I wasn't giving the go-ahead for 9+ hours of downtime.

Hello - I'm attempting to preclear a 4TB drive to expand my array but after each successful preclear, the array appears to want to Clear it again before adding it. I've attached diagnostics, preclear reports and a screenshot of the "Start will bring the array on-line and start Clearing new data disks" message I'm concerned about. Please let me know what else might be helpful to troubleshoot. I'm hoping to avoid multiple hours of downtime by pre clearing and the language I'm seeing seems to tell me thats what unRAID intends to do once I click start. Am I misunderstanding the meaning or is something not right? Thanks for your help, Brian tower-diagnostics-20170215-1213.zip TOWER-preclear.disk-20170215-1211.zip

In Unassigned Devices, you can see a X icon next to the disk serial which can be used to clear the old session. In Tools > Preclear Disk, that icon exist too with same functionality. FYI for Mac users - I was experiencing this issue as well. I have a slot dedicated to pre clearing disks for this and other NAS I have. In Safari, clicking the red X on the Preclear plugin page did nothing. Switched to Chrome and it acted just as you said it should. Not sure why it behaves different in Safari. Side question: Can the plugin be modified to read the serial and if it doesn't match the last preclear on record, it behaves as if no prelcear has been done and presents users with "Start Preclear"? Thanks for this awesome tool! I'm macOS user too, and I can't replicate the issue. Every time a user complains about it, I open Safari and it works strait forward. Can't patch what I can't replicate, I'm afraid. If you can invite me on a remote TeamViewer session, than I can investigate it using your setup. Thanks. I just purchased two 6TB drives to replace my current parity drives which will then be moved into my array as data drives. I expect I'll be running at least 2-3 additional pre-clears during this process. Assuming I encounter the issue moving forward, I'll PM you to find a good time for TeamViewer. Appreciate the offer.

I first mentioned this twelve pages ago. Whoops, sorry about that . I did read back several pages in the thread, but admittedly could have searched for "Safari". Thx for pointing out this has already been identified.

Do you mean that you physically move the drive without shutting down the server? I stop the array, pull the drive, relocate the drive, restart the array. So when I hover over the red X, the tooltip says "Stop Preclear" (obviously there isn't one ongoing) and clicking it refreshes the page, but doesn't actually change anything that I can see - I've still no option to start a preclear. Pretty sure by now that Im missing something obvious, but not sure what it is! Is it mounted by Unassigned Devices? I just got some help from gfjardim via PM - my problem was that I was missing the Unassigned Devices plugin - with it I was able to kick off my preclear as I wanted. I'd just like mostly to give thanks to gfjardim for his help here - there wasn't a bug, rather a misunderstanding on my part, and the support I got was the kind of top notch you'd not dare hope for even if you'd parted with a great deal of money. Really above and beyond the call of duty and I am very thankful. Outstanding As a follow up to this, I've established that it does count as a very minor bug - the problem is that the 'stop pre clear' Red X button doesn't clear down the status of a device if you click it in Safari. It works just as intended in Chrome. Just submitting for clarity! I can confirm this bug in Safari. I have a drive that has had some problems in another storage system recently so I put it in unRAID to run preclear on it. After one preclear, clicking the red X in Safari (I wanted to start another) did nothing. I finally saw this post and installed Chrome. Clicked the red X and I'm ready to run a preclear again on this drive. Thanks!

Thanks again for this plugin, I love it. The one issue I'm still having is with disktemps polled through SNMP. It looks like it's going to work when I try via snmpwalk, but I get nothing. Running the drive_temps.sh manually works fine. Polling "sharefree" via snmpwalk works as expected and my .conf looks ok, so I'm stumped. I saw some mention earlier re: scripts not having enough time to run... was that resolved? How can I see if that's what's happening to me? Linux 4.1.18-unRAID.

I've moved on to trying the LibreNMS fork of Observium. I love it so far. The community/authors seem much more friendly as well. I'd recommend it over Observium at this point.

Wanted to add my thanks for this plugin. Using the Observium VM Appliance is the way to go (I set it up on my ESXi box). Looks great and all the info appears accurate.

This is amazing Zeron, thanks again!

Similarly to @trurl's suggestion, I have an OSX VM running that mounts unRAID shares at boot. I then have Arq configured to backup these shares. Personally, I'm using it to back-up to Amazon but it can also backup to Google. *Note: I don't believe the Windows version of Arq allows backing up network drives yet. This feature is presently only available on the OSX version.

This is fantastic! Thank you very much. My ultimate ESXi build is now complete.
