Hi @all
I'm having an issue when Unraid boots its not geting the "real" serial numbers of the disks. Somtimes another reboot helped - but after I updated to 7.0.0 some hours ago I'm not able to get my array running - with out array - it's not making fun 🙂

Details: 

/dev/sda has the serial: 
 

root@unraid:~# smartctl -i /dev/sda
smartctl 7.4 2023-08-01 r5530 [x86_64-linux-6.6.68-Unraid] (local build)

BUT:

root@unraid:~# lsblk -d -o name,serial /dev/sda
NAME SERIAL
sda  0000000000000001

And what I think Unraid is doing: 

root@unraid:~# udevadm info --query=all --name=/dev/sda | grep ID_SERIAL
E: ID_SERIAL=ST16000N_M000J-2TW103_0000000000000001-0:0
E: ID_SERIAL_SHORT=0000000000000001

So the disk has a serial but is not corretly recognized thats why I tried to force to detect the serial by adding
 

libata.force=noncq

into the syslinux configuration - but did not help. 

 

Anyone has a clue how I can fix this issue ? 

Best regards
André
 

How are these drives connected?

Good Question sorry for not mentioning directly: 

 

Via USB 

Devices directly on the SATA Controller have no issue like that. 
 

This is a common problem with USB and one of many reasons it is not recommended for assigned disks. Maybe something for you here:

 

 

If you need more help post the output from:
