ThePhotraveller Posted November 2, 2020 Share Posted November 2, 2020 Hei guys the rebuild started but had to be interferred because of repeated power cuts here. I tried to rebuild today. Its showing 1000 days something for the finish time. also the speed is very very low. Like even KB's at times. Can you guys check with the posted diagnostics for whats happening ? tower-diagnostics-20201102-1601.zip Quote Link to comment
JorgeB Posted November 2, 2020 Share Posted November 2, 2020 There are read errors on disk1, you should be alerted for that (if notifications are enable), if you continue the rebuild disk will have corruption, cancel, replace cables on disk1 and try again. Quote Link to comment

Hurray !! thanks man. But a general query how do cables wear out physically? just by conduction? Quote Link to comment

jon928 Posted October 20, 2021 Share Posted October 20, 2021 Hi guys, Was wondering if I could get some help. Getting the same issue about the Device being disabled - contents emulated. Attached I have included the Diagnostics and SMART report. I have another hdd on standby I can use to replace Disk 2 but if I don't have to toss the disk I'd rather not. Any help would be greatly appreciated. Thanks. Jon scornflix-smart-20211020-0914.zip scornflix-diagnostics-20211020-0914.zip Quote Link to comment
JorgeB Posted October 20, 2021 Share Posted October 20, 2021 You should always start a new thread, but since you're here, there were simultaneous errors on 5 disks, disks 1 through 5, disk2 got disabled because it was the first to give write error, it could happen to any of the 5, this is usually a power/connection problem.

Thank you for the quick reply. Should I start a new thread now or just go w/ this one? My server is connected to a UPS and I was seeing some UPS warnings about loss of communication. Should I just shutdown the server and connect the power cable to regular Power strip? Also - a parity check was completed yesterday and it says Parity is valid Last check completed on Wednesday, 10/20/2021, 07:27 AM (today) Finding 2560 errors Duration: 1 day, 3 hours, 57 minutes, 35 seconds. Average speed: 139.1 MB/sec Thank you for your help. Jon Quote Link to comment

You can but unlikely to help, since only a few disks had an issue, see if they have something in common, like a power cable/splitter. Quote Link to comment

I'm using 2 of those hot swappable cages that house 5 hdd bays each. Parity drive and drives 1-4 are in one cage and drives 5-7 are in another cage. I have 2 more hdd's on standby in bays 9 and 10 ready to deploy. Since it's drives 1-5 that showed an error and drive 5 is in a separate bay. Drive 5 and Drives 1-4 don't share anything like a cable/splitter. Having only 1 parity drive and having 1 hdd out of commission is making me nervous. I used to have 2 parity drives but then started thinking it was overkill since I haven't had any issues for like 4 years with another service and 3 years so far with my current server. So I got rid of the 2nd parity drive. Should I just go ahead and take out Drive 2 and rebuild the array using one of my spares? Thanks. Jon Edited October 21, 2021 by jon928 Quote Link to comment
JorgeB Posted October 21, 2021 Share Posted October 21, 2021 You can rebuild on top of the old disk, just make sure the emulated disk is mounting and contents look correct before doing it. Quote Link to comment

kysdaddy Posted July 18, 2022 Share Posted July 18, 2022 I just found two disabled disks on my system, any chance that these are same and can be re added to the system, I have 2 parity drives. Thanks for any help Chas tower-diagnostics-20220717-2215.zip Quote Link to comment

Runrunrun Posted September 8, 2023 Share Posted September 8, 2023 Helle everyone, I am having issues caused by a Seagate HDD in my Unraid System. Its still in test mode so no real data issue. Still I want to ask you to look at the log file so I might know more and whether I need to replace the disc or the root cause might lies somewhere else. Setup: One parity drive, one cache drive and one in the array. The one in the array is causing issues. Issue: in „main“ the disc in the array is marked as disabled and has 1024 errors. Attached you can find the log file. Do you need any other information? Kind regards Toby Portierungsformular EDNT.txt Quote Link to comment

JorgeB Posted September 8, 2023 Share Posted September 8, 2023 Looks more like a power/connection issue, check/replace cables and post new diags after array start. Quote Link to comment

The new documentation doesn't really exist and the old one https://legacy.wiki.unraid.net/Manual/Troubleshooting seems differtent. I did some tinkering with APSM roots and one of the drives has disabled. It will only be some minor file if at all (as my array shares are mainly read only) and I would prefer to not rebuild a whole drive as it takes about 32hours.

trurl Posted January 19 Share Posted January 19 You either have to rebuild the disk, or New Config and rebuild parity instead. Otherwise, your array will be out of sync. If you are sure none of your array has been written, you could New Config and Trust Parity, but you would need to do a parity check to verify. 1 Quote Link to comment
