🙃 I should have read better before posting. Thanks anyway

Hello, I just got myself a new APC UPS. Way over my needs, my Unraid barely uses below 10% of its capacity. And still today I had the power cut off, maybe for 4 minutes, and as it seems Unraid power off was initiated. I expected the UPS to hold it on for at least 20 minutes before initiating shut down. At least it was not an unexpected shutdown forcing it into a very long parity check. I just wish I could do something to prevent that in the future. I attached a screenshot of my UPS settings.

It took me some time to assemble everything but eventually I did it. Thanks to your advice I have now 15 HDDs + NVMe loaded into a Fractal Design Define 7 XL and I have plenty of room to grow. You were of great help.

Jorge this is unclear to me. In 4 days I had 3 parity checks that ran. 2 unrequested and one actionned manually. All of them finished with around 20500 errors. Those errors are not detailed. Isn't there more information in the syslog about that? Is there a debug mode? I would like to be reassured that I have parity on my server.

So right after your answer I started a Parity check manually with correction. And a day later I get this exact same result with 20500 errors. I am concerned because I have 2 X 4Tb parity disks and I don't know what will happen if I lose a disk, will I be protected? Even when I run the Extended Fix Common Problems plugin it ends with a Found Errors notification, but no errors appear on screen to be corrected. novanas2-syslog-20210321-0731.zip

7 years with Unraid and I never knew that. Thanks Sent from my iPhone using Tapatalk Pro

The checkbox "Write corrections to Parity" is always checked on the Main page. But these last 2 parity check that ran ran because of "ungraceful shutdowns" so I did not started them myself (and that is weird because in fact I only chose to reboot). So you think that these self started parity check ran without the "Write corrections to Parity" activated?

Hello, That's the second time I run parity check and get around 20000+ errors while none of the disks show any errors. What errors are they? Where do I find and correct them? novanas2-syslog-20210320-1017.zip

No everything was in place and working when I decided to install the NUT app. NUT is not that important for me to retry I guess. Thank you very much for your help

Considering your pedigree you probably know what you are talking about. What do you think happened? It happened exactly as I wrote it. Everything was fine. I ran the install of NUT, got that message in the script about Unraid being too new, and then I didn't even have time to press the Done button for the install docker crashed and the rest is told in my messages up there.... Anyway what the NUT app would give me with my APC UPS that the built in features won't?

I won't try it again that's for sure. And I maintain that while the install script was running it warned about my version being too new and that it was at my own risk, but it did not offer to stop or abort.

Great advice. I took my flash to my PC and removed any remnants of this NUT app (folders and files) and also looked for any later changes. After I was satisfied I plugged it back in Unraid, took a deep breath, and rebooted. Apart from the fact it detected an unclean shutdown and started a parity check everything looks fine. Small price to pay. Is there any integrity check I could run to be sure? Any flash cleanup tool maybe?

Then definitely USB controller because that crap of an app. It took control I guess to connect to the UPS but wrecked a havoc instead. What now?

Wrong. While it was installing I clearly saw a warning that my Unraid version is too new and is not supported but this ^#%$ app did not stop and proceeded until the docker service crashed and something made my flash drive disappear. This might even appear in the syslog I posted. For the moment I could go on like that since all the apps work and the volume is accessible, but what concerns me is that my APC UPS is not visible anymore and I cannot renew the connection with it because of that ^&%^$^ NUT app.

I could try another USB port to refresh the reading of the flash. But most importantly I need to be reassured. Accessing the settings page still shows remnants of that crappy app called NUT, and I cannot remove them of course. Is there something I could do on the flash drive on my PC to "clean" it from any new files or modifications this NUT app made and that "could" prevent a clean reboot? This is what shows if I click on the Flash drive in the Main page.

Why? My flash drive is passing the chkdsk test now, it is readable on my PC, my Pro key file is in the config folder, and I can have access and backup if necessary any files or folders on the flash drive, but only on my PC. If I click on view the flash drive content on the Unraid page it says 0 file 0 directories. But that might be because of what happened. Maybe I could reboot the server but I am just too scared to do that before I check every thing first. I really don't want to go through the long parity check, app installs and configuration again.....

Anybody???? Please ! In the meantime I retrieved the flash, without powering down, and I scanned it. I found errors and they were corrected. The flash is readable on my PC. The key file seems to be still in the config folder. Reinserting it did not help Unraid find the key yet. What is next? I am not powering down unless I get some help to save my configuration.

Are you sure? Note that the flash drive have been corrupted by this NUT app installation. And that everything is still running so powering down might leave me without a server in the end and I will need to start from scratch. I know the volume will still be there when I mount it with the right disks and all but all my apps and configuration will be gone right? Or are they safe because sitting on the cache drive?

Hi, I just installed an app called Nut something to monitor my UPS on a perfectly working 6.9.1 Unraid and all of a sudden all hell broke loose. My dockers went down. Docker service won't start anymore. But the installed apps still run and are accessible. Unraid is still available but saying it is missing the key file. I am scared to reboot or do anything. BTW accessing my Unraid from the network the flash drive looks empty. No surprise it asks for a missing key. What can I do? Would it help if I retrieved my flash drive while Unraid is still running and loaded in memory, prepare the flash drive as new with the latest Unraid version, insert the pro key file I still have and reinsert the flash drive? And if I manage to do that, is there a way I could "export" my present running configuration to the newly prepared flash drive, as if nothing happened? novanas2-syslog-20210319-0829.zip

Hello, I do not understand what is the apcupsd-influxdb-exporter. I have an APC UPS connected to my Unraid server. I wish to see more information on my UPS (alerts, statistics, etc...) on my Windows PC. Is that useful to achieve just that?

Hello, I am at a crossroad now. I upgraded my Unraid to a new machine, much bigger. And now my UPS seems to be unfit for the task anymore. I had to disconnect it as much as I hate that. Is there a UPS calculator so I can decide what to purchase? I'd rather calculate taking into account the full capacity of the Unraid server in the end which will have 18 HDDs. I am at 15 + 1 NVMe at the moment. Thank you

I don't have it but the extended test showed everything in green. My question is is their tool (WD) reliable enough to decide that this disk is good in the end? Did anyone have a similar experience? On the other hand can anyone propose a method or tool to definitely decide if this disk is good or not ? (in the meantime I had another one exactly like that from another machine so that makes two)

As I said, the disk has been replaced already. Will the log help in that case? In the meantime my UPS has died so don't pay attention to the latest events. The disk that has been replaced is #5. novanas2-diagnostics-20210309-0956.zip

Hello, One of my HDDs, a 7 years old 4Tb WD Green drive suddenly showed some 30 reading errors while building parity. Of course after the Parity successfully finished I replaced it with a new one. But in doubt I ran an extended test on the drive using WD tools. After some 7 hours the extended test showed a well green lit Pass. What does it mean? Can I trust the WD tool extended test? Does that mean the drive was fine all along? Maybe I had a cabling problem that is now solved? I just finished transferring my Unraid to a completely new machine.....

Aborted. Disabled parity. Restarted the array. This time I am copying controlled amounts into specific disks. And still the speed is barely improved. 59MiB/s. What's the bottleneck now? P.S: Just out of curiosity. I tried to copy using my Win10 desktop, using 2 mapped drives. And the data flies..... And I thought putting the load on Unraid would help..... There must be a problem somewhere....
