Things had been running well since I replaced the controller card in my server with a non marvelI controller. I recently added a drive to my array (disk4). I woke up this morning and had an alert in my email saying the drive was offline. The drive that I installed was a used drive that I pulled from an external drive. I thought that perhaps it was just bad and needed to be replaced, but I ran the diagnostics and saw errors on other drives as well. Can anyone give me an idea of what might be going on? Thanks! l33tnas-diagnostics-20230620-0728.zip

I gave it a reboot and it came back up. Disk 2 is showing as "device is disabled, contents emulated" Here are the new diagnostics. l33tnas-diagnostics-20230524-0731.zip

Without shutting it down and opening the case, I am not sure. I know I ran out of SATA ports on the motherboard and have a contoller card with 1 drive plugged into it. The rest are plugged into the motherboard. It would seem that the Marvel controller is the one built into the motherboard. The jmicron must be the one with the single drive plugged into it. At this point it seems like my best (and cheapest bet) would be to ditch the onboard Marvel controller and get a PCI card that can support 8 devices? Or maybe even better, another 4 port jmicron? I found the information about the Marvell controllers NOT being recommended as they can drop drives, just like mine is doing. I might actually have another SATA controller up in the attic in my PC graveyard. Am I safe to shut down and verify what drive is connected where? If I so should I restart in maintenance mode? After that, what are my next steps? I do have EVERYTHING backed up at this point.

After my drive failure and corruption a couple a months ago, I set up alerts to let me know if anything was going on. I got an email today that there was an error on my array. When I checked I see that disk 2 is offline and disks 1, 2, and 3 have 669,627,864, 669,627,864, and 669,627,928 errors respectively. The shares are still accessible. Disk 2 is the slot I had problems with last time (I have since replaced the drive) and have had issues with it dropping offline. I am 99.9% sure I have swapped it SATA cables and ports and the issue stayed with disk2 no matter where it was but I can certainly do that again. I learned my lesson last time and gathered logs before I am rebooting. I'm not touching anything until a smart person gives me advice l33tnas-diagnostics-20230523-1848.zip

You were exactly right! I ran a check on all the other drives, disk 7 had some errors and as soon as those were fixed the data in my shares is showing up again!

This implies to me that in the first case you are looking in the ‘data’ share, whereas the other one is looking in the ‘blue-ray’ share? My fault. Typo. If I browse to l33tnas\data\blu-ray I see an empty directory, if I browse to disk1\data\blu-ray the data is there. So I would run the xfs_repair -v /dev/(drive number) for each disk correct? After I have checked all my other disks (I might as well at this point) should I reformat the bad drive and let it rebuild and the array and THEN replace it, or can I skip that step and just pop a new drive in that slot? Thanks everybody for helping me work through this!

Yes. As I mentioned in my earlier post, I have already backup up all the available data on all the remaining drives in the array and used UFS Explorer to recover all of the data I could off of the failed drive. My question is, where do I go from here? Currently the array is started with the one disk missing. Not all files are showing up on the shares (but do exist on the remaining disks) but I have read this is normal when you have corruption. For example, I have a blu-ray directory where I store an ISO backup of all my blu-rays. If I browse to l33tnas\data\blu-ray the directory shows as empty. If I browse to \\disk1 (or 3, 6, 7, or 8\blu-ray the data is there. I'm guessing my first step would be to replace the failing drive since it had thousands of SMART errors. But once I do that how do I fix it so the shares can see all the files on the other drivers? Do I need to wipe everything and copy all files from scratch like I was building a brand new system?

Here is the xfsrpair log as requested. I also attached new diagnostics since the drive is back in the system. Thanks! xfsrepair.txt l33tnas-diagnostics-20230426-2136.zip

Hello! I am running a Unraid server with 1 pairty drive, 6 data drives, and 1 cache. I had a drive fail, it seems to have been a hardware failure, a SMART report shows 2814 "uncorrectable error in data" errors, ER -- ST COUNT LBA_48 LH LM LL DV DC -- -- -- == -- == == == -- -- -- -- -- 40 -- 51 00 00 00 01 7b 64 94 37 40 00 Error: UNC at LBA = 0x17b649437 = 6365156407 And the recover software I am using gave me this: Warning: Storage defect was detected in "read" operations of: This error indcates the storage device failed to complete a read request due to error. The power blinked and for whatever reason the UPS didn't hold, when it came back up disk 2 was showing as unmountable. I didn't do things the correct way, I am so used to UnRaid being foolproof that I didn't run dianostics to post when I saw the error, I just shut down and hoped for the best. (I've been up and running since 2015 with no issues other than the occasional drive failures where is disables the drive, emulates it, and I run a couple of days until the new drive comes in and I just swap and it rebuilds and I am fine) I referenced the "check file systesm" wiki and ran through the steps to check an XFS drive. It couldn't find the superblock or any secondary superblock. Currently the array is started with the one disk missing. Not all files are showing up on the shares (but do exist on the remaining disks) but I have read this is normal when you have corruption. For example, I have a blu-ray directory where I store an ISO backup of all my blu-rays. If I browse to l33tnas\data\blu-ray the directory shows as empty. If I browse to \\disk1 (or 3, 6, 7, or 8\blu-ray the data is there. I have all data from the other 5 disks backed up to external drives. I am running a recovery on the dead drive with UFS Explorer to get any of the data I can. Where do I go from here? Is there any way to recover what I have without starting from scratch? I see a document about replacing the boot drive and adding existing data drives back in to the array, all my drives are clearly labeled so I know which one is the parity disk, but I am more concerned about the config and all the shares, I don't really want to try to reinvent the wheel on all of those. I am attaching the current diagnostics, if there is any other info I need or if I need to pop the failed drive back in and run diagnostics again let me know. ps. If it looks odd in my config that I have disks 1 2 and 3 and then 6 7 and 8 there is a reason. When the array started getting too large I stole a couple of drives from it and started ANOTHER Unraid server I just never took the time to renumber the drives (although it does bother me) Thanks! l33tnas-diagnostics-20230422-1008.zip

And an update. They are gone again. They were probably coming up every time for a minute after the reboot and I wasn't quick enough to notice. So I'm still stuck. And I am running on the latest version, etc. etc. I may just put everything back on the old AMD machine and see if it starts working again. The i7 didn't appear to make any performance increase anyway, I can use it to upgrade the PC in my arcade cabinet.

I ran into the same problem. Last night I upgraded my box from the old AMD box to an i7. (I upgraded my main PC to an i9) No shares. I could see all the drives and the data, but not the shares. I installed the fix common problems plugin and it didn't find anything that looked relevant. I had probably rebooted at least 6 times in the past 15 hours. I found this thread an uninstalled Network Stats, rebooted, and all my shares are back.
