StewLoft Posted August 6, 2022 Share Posted August 6, 2022 Hey there, I need some help. I have an unraid (6.9.2) system that I have had in operation for about 2 years now. I have never had any issues. It is mainly used for media and for backing up several computers. I recently had the opportunity to purchase 3 - 12TB HDD's. I had a 6TB Parity, 4 - 4TB HD, 4 - 3TB HDD, and a 240GB SSD. Never had an issue. I precleared 1 of the 12TB HDD and then added it to Parity so I could add the other 2 - 12TB down the road. After the 12TB Parity was installed and running good I removed the 6TB Parity so I could add a 12 TB HDD. This went fine. I added a 12TB HDD to the Array, all good. I added the last 12 TB HDD, all good. After about 1 day one of the 4TB HDD in the array failed. I checked sata and power cables, even switched the cables from another HDD in the Array, no change. I removed the effected 4TB HDD from the Array assignment. After I brought the system back up orange triangle with exclamation. I started read-check but it is saying 176 days to complete. Do I really have to wait for half a year to get back to parity? With read-check working on the system I am not able to access a lot of the data on the system. I am not well versed in Unraid. I have a few Dockers but don't use them much. As I said I use the system for media (Emby) and for back-up. I have not had a reason to do much else in unraid, and frankly did not want to do something that could cause a situation like I am in... Quote Link to comment

StewLoft Posted August 6, 2022 Author Share Posted August 6, 2022 Here is the diagnostic report. tower-diagnostics-20220806-1119.zip Quote Link to comment
trurl Posted August 6, 2022 Share Posted August 6, 2022 Why do you have parity2 but no parity? Quote Link to comment
trurl Posted August 6, 2022 Share Posted August 6, 2022 And it looks like what should be your cache you have assigned as disk22 in the parity array Quote Link to comment
StewLoft Posted August 6, 2022 Author Share Posted August 6, 2022 Parity 1 was a 6TB HDD. I had to remove it from the Array to add the 12TB HDD. I tried moving parity 2 to parity but it would not let me. Quote Link to comment
trurl Posted August 6, 2022 Share Posted August 6, 2022 Disk1 has corruption but is mounted. That shouldn't affect parity check anyway. Not sure why we are talking about read check. Post a screenshot of Main - Array Devices. Quote Link to comment
StewLoft Posted August 6, 2022 Author Share Posted August 6, 2022 Yes, disk22 was part of the original build and I just left it there. Planning on re-assigning to cache but I guess that will have to wait until I get everything back in order. Quote Link to comment

StewLoft Posted August 6, 2022 Author Share Posted August 6, 2022 I read somewhere in the forums about running the read-check if parity is not valid. Quote Link to comment

Why do you think parity is not valid? Don't really see what the point of read check would be even if parity wasn't valid. Quote Link to comment

I originally had a 6TB parity. I wanted to add a 12TB to the array so I added a 12TB to parity2, then I could not add the 12TB to the array as the 6TB was smaller. I deselected the 6TB, everything was fine, then added the first of 2 12TB HDD's, everything was good, added the last 12TB HDD, then shortly after a 4TB (disc1) failed and this is where I am at.

Don't really see what the point of read check would be even if parity wasn't valid. When the system finished bringing the array up I had the orange triangle with the exclamation and it showed Array started, parity not valid. I thought the read-check would go through and validate the Array. What actions should I take instead? And thank you for looking at this!! Quote Link to comment

trurl Posted August 6, 2022 Share Posted August 6, 2022 If you aren't using tabbed view, then Array Operation is at the bottom of Main after all the devices Quote Link to comment
StewLoft Posted August 6, 2022 Author Share Posted August 6, 2022 Sorry, I was confused on what you meant. Quote Link to comment

Your previous screenshot showed parity2 green and diagnostics doesn't say it is invalid. Did you let parity2 rebuild finish or not? Quote Link to comment
StewLoft Posted August 6, 2022 Author Share Posted August 6, 2022 Yes, after I added the 12 TB to parity it showed valid. After I removed the 6TB parity it was valid. It went invalid when disc1 failed. Quote Link to comment
trurl Posted August 6, 2022 Share Posted August 6, 2022 1 minute ago, StewLoft said: It went invalid when disc1 failed Where is it saying anything is invalid? Quote Link to comment
trurl Posted August 6, 2022 Share Posted August 6, 2022 3 minutes ago, StewLoft said: Yes, after I added the 12 TB to parity it showed valid. Not entirely clear. What I asked more specifically is did you let parity2 rebuild finish? It would have taken many hours. Looks like your syslogs go back a couple of days. Let me read through those and see if I can answer some of my questions. Quote Link to comment
