trurl Posted November 24, 2020 Share Posted November 24, 2020 Go ahead and start in normal mode. Quote Link to comment
boosted Posted November 24, 2020 Author Share Posted November 24, 2020 disk 3 and 5 show emulated with red X and no unmountable labeling for 3 and 5. Nothing in the unassigned section. here's the diagnostic. unraid-diagnostics-20201123-1928.zip Quote Link to comment
boosted Posted November 24, 2020 Author Share Posted November 24, 2020 The data that were gone in maintenance mode are back, mainly the things I copied over the past month or so. But I don't know if I'm missing anything though. Quote Link to comment
trurl Posted November 24, 2020 Share Posted November 24, 2020 Since the emulated disks are now mounted, you should be able to rebuild them. The emulated contents are the same as what will be written to the disks, it is all just the result of the parity calculation. I don't see a lost+found share so I don't think anything got dumped there. You should be able to look at any of your shares or disks now, but of course it may be difficult to figure out if anything is missing. Disk3 looks to be about half full but disk5 looks mostly empty. I don't know if that is how it was before or not. Quote Link to comment
boosted Posted November 24, 2020 Author Share Posted November 24, 2020 Thank you for helping me get this far! I honestly don't think I lost anything, but I will see over time, I can most likely recover the last 2 month, i think that's how long they've been down. So does no lost+found mean nothing was lost? Or that nothing that was lost can be recovered? What is the rebuilding process from this point? The wiki didn't say what to do to rebuild after a repair. I don't want to assume anything. As for what happened, can you speculate anything? Maybe those 2 drives lost power at some point and corrupted the data? Should I still trust these 2 drives or should I get replacements for them?

You can run an extended SMART test on them if you want. Click on each disk to get to its page to access the self test. Extended test will take several hours but you can do them both at the same time. If they pass then I would trust them. But if you rebuild to new disks then you have the originals as backup in case there are problems with the rebuild. On the other hand, the originals are probably corrupt and would have to be repaired just like the emulated disks did. Lots of good reading here: https://wiki.unraid.net/UnRAID_6/Storage_Management#Replacing_disks Quote Link to comment
boosted Posted November 24, 2020 Author Share Posted November 24, 2020 Ok, I will do that. Extended smart test, then stop array, unassign disks, start array, stop array, assign disk back then start to rebuild. According to the wiki. Thank you again. Quote Link to comment
boosted Posted November 24, 2020 Author Share Posted November 24, 2020 One more question, can I rebuild both drives at the same time? The wiki didn't say whether that's advisable or possible. Quote Link to comment

Here are their reports. I think I'm ok to proceed. But I'm not sure if some the attributes numbers are good. Most say "old age" eventhough it's just 2 years old. unraid-smart-20201124-1215-disk3.zip unraid-smart-20201124-1215-disk5.zip Quote Link to comment
boosted Posted November 24, 2020 Author Share Posted November 24, 2020 12 more hours til rebuild is done. I'll pick up some drives during this BF sale if possible as spares. Prices have gone down since when I built it. Quote Link to comment
boosted Posted November 25, 2020 Author Share Posted November 25, 2020 Rebuild completed without errors. It does not appear that I have lost any file, at least that I can tell. As long as the loss is the whole file and not chunks of it. That'd just corrupt the whole file without me knowing it for a long while. Spare HD ordered as well. Thanks again trurl for your help on this. Quote Link to comment
