Good Evening Everyone,

I have connected two working USB drives, newly formatted with ext4 (checked on other systems and they are working fine). I want to mount both of them using their UUID, but the system doesn't recognize them. Lets get to some data around

#1 Version
Code: 
sathish@home:~$ pveversion
pve-manager/8.2.5/12c0a59769080547 (running kernel: 6.8.12-1-pve)

Please help me in resolving this issue
 
Thank you for the response, here is the output from dmesg -w.

Asking for cache data failed - Google'd this and found that this is not an error as USB drive does not have any cache, it is reflecting the same and attaching the USB drive as a SCSI disk.

hi,

before all, try another usb port, idealy with another usb controller.

If was on USB3 port, try it with usb2.
Problem encountered before, with usb JBOD 4 hdd 18To each. Solved via forcing usb2 usage. ( sufficient for my use case, see if good for U :)
