Disk is Disabled - Any ideas?

[Mike-R49Pqj]

Not sure what would cause this to happen. Might be related to a power outage but logs show that the UPS worked properly. 

 

Drive is only a couple months old and has never thrown errors until now. 

 

UPDATE: I can access all the contents of this disk but there is still a red x by the disk and it says "contents emulated". 

 

Thank you!

Disk dropped offline and reconnect with a different letter:

We really discourage using USB disks as array devices, both for performance and reliability.

None of my array disks are connected via USB - all are running off HBA cards (LSI SAS3008). I did have a portable backup drive connected via usb but only used it as an 'unassigned device'. Could that disk be showing up in my array for some reason? I was able to access all the files saved on this disk but on the 'Main' tab it still says its disabled.

This disk that was assigned as disk7 is connected by USB:

 

May  7 18:43:03 FULSERVE kernel: mdcmd (8): import 7 sda 64 7814026532 0 ST8000DM004-2CX188_ZCT0D23R
May  7 18:43:03 FULSERVE kernel: md: import disk7: (sda) ST8000DM004-2CX188_ZCT0D23R size: 7814026532
May  7 18:43:03 FULSERVE kernel: md: disk7 new disk

 

It was sda, after it dropped and got picked up again it became sdm.

I see what you mean, its just very confusing. All of the disks are connected internally via two HBA's. I don't understand why it would think its connected by USB. Do the other disks look to be connected via USB? They are all exactly the same setup. 

 

I tried unplugging the usb hard drive then restarting and now my disk 7 shows "Not Installed" yet I can still access the files. However, when I try to plug any portable hard drive in through usb, it thinks the drive is xfs even though its exFat. It allows me to run a File System Check and returns the attached results. fsck.htm

 

This makes me believe that Unraid is seeing the USB device as the disk 7 array device even though the original drive was an internal (non usb) drive.

It doesn't think, it is.

It's the only disk using USB.

That's because it's now emulating the disk.

Thanks again for your help. I have scrubbed through the logs and it looks like when I added a new drive to the array on may 7th I accidentally added the external hard drive instead of the new internal hard drive. The drive I ordered must have been DOA and probably just didn't show up as an option. 

 

Do you have any ideas for how to recover this data or how to get this drive online again? The emulated data seems to be intact from the few files I have copied over but I don't understand how emulated data works.

You just need to rebuild to a new or the same disk, but recommended using an internal device.
