ssd read cache - problem

[xigloo]

good mornig guys, is it well?
sto configurando un disco ssd di cache in lettura in proxmox VE6.4 e quando invio il comando zpool add -f rpool cache /dev/disk/by-id/0x50026b7282a19105 , compare questo errore : cannot resolve path '/dev/disk/by-id/0x50026b7282a19105'
qualcuno ha avuto mai questo errore ?

:[

grazie ancora

What is the output of ls -l /dev/disk/by-id/? Maybe you have a typo in the number?

for ssd , output is :
wwn-0x50026b7282a19105 -> ../../sda

i've selected 0x50026b7282a19105 only .... is this my mistake?
