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)

#2 USB Drives

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.

I just found this and my bad I always ignored the messages after the disk was attached. is my USB drive getting reset?

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 :)
