Hi All,

 

Repeating problem here, hoping someone has a solution. Attached is my diagnostics zip(Yes it is empty, that is literally what it's spitting out when running diagnostics)

 

unRAID Version: 6.5.3
 

Problem is unraid on boot is not able to find /dev/disk/by-label/UNRAID

• I have confirmed that the USB is formatted fat32, label is UNRAID(no spaces or special chars all caps etc)
• I've tried multiple USB's
• tried to manually find the drive by ls /dev/disk/by-label ( return by-label does not exist in /dev/disk )
• Drive can be manually mounted fine by using /dev/disk/by-id || /dev/disk/by-path ( mount /boot /dev/disk/by-id(path)/<drive identifier>
• Checked that the label is present on the device when booted into unraid (mlabel /dev/disk/by-id/<identifier>-part1 -i :: )
• Tried enabling/disabling ehci pass-off
• The motherboard only has USB2 ports, so usb3 isn't the culprit here.
• Desperate effort attempts
  • Copy unraid to sata hdd, make bootable, boot from it, plugin usb after kernel (before os loads) has loaded (Hoping to avoid bios interaction of the drive at boot and purely rely on echi passoff).
  • Tried disabling VT-d in case it was IOMMU doing some funky stuff.
  • Tried disabling virtualization completely
  • Tried both UEFI and Legacy Boot
  • Kicked the machine a few times (now I have a sore foot, 0/10 would not recommend)

 

System Specifications:

• Intel Xeon E5-2660 (v1)
• 64GB DDR3 ECC 800mhz ram
• Supermicro X9SRL-F Motherboard (bios: r3.2)
• LSI 9211-8i HBA in IT mode + 6* WD RED 2TB drives.

 

Any help would be appreciated, if I was able to edit fstab or overwrite it during boot to simple change the mount location from /dev/disk/by-label to /dev/disk/by-id or something that would be great, or have it just simply find the first drive partition /dev/sda1.

I downloaded version 6.3.5 and was able to get a valid diagnostics out of it.

 

I noticed this in the syslog:
Jun 28 03:53:16 Tower kernel: usb 2-1.3: new high-speed USB device number 4 using ehci-pci
Jun 28 03:53:16 Tower kernel: usb-storage 2-1.3:1.0: USB Mass Storage device detected

Jun 28 03:53:16 Tower kernel: sda: sda1
Jun 28 03:53:16 Tower kernel: sd 0:0:0:0: [sda] Attached SCSI removable disk

But I don't notice anything wrong with it, still no device in /dev/disk/by-label/UNRAID. I manually mounted the USB to /mnt/usb to copy the diagnostics off (incase you see it somewhere in the logs)

again, mlabel confirmed the usb drive had a label.

So I've ordered a bunch of different USB drives. Assuming this is the problem as when I copied unraid to my external SSD(USB) it booted no worries but had a blacklisted GUID.

 

Somehow the 9 unique flash drives I tried all encountered this error...

Can you tell us which brand, model and size are you trying to use?

I'll have to get a list of them later, I'm just currently trying to get this setup as I'll need it for my studies next semester.

 

I have managed to find a USB that works, and Sandisk Cruzer Facet 8GB, :D
