@Davidj-0 Merci pour le retour, j'utilisais aussi une Debian pour mon test ^^

@olivierlambert A little feedback regarding my problem that some may have in the future in the case of purchasing an external box which will be connected to an XCP-NG host. It turns out that the Sabrent brand box that I bought will not work with XCP-NG, there would be quite a few basic problems. To see if with a more recent kernel in the next XCP version this resolves the problem or not. I tried the bypass with a uas blacklist without success the box remains blacklisted : touch /etc/modprobe.d/blacklist-usb.conf echo "blacklist uas" > /etc/modprobe.d/blacklist-usb.conf reboot But none with an old box (5 storage spaces in USB3) which is not black listed. Subject on the site Kernel.org (Kernel 4.18.12) : https://bugzilla.kernel.org/show_bug.cgi?id=201421 https://lore.kernel.org/all/CA+icZUXHnc-Qd9NhwxFx3+LQakNTWmS_RRYsTAY8-gO8wc219Q@mail.gmail.com/ Amazon (user feedback with similar problems) : https://www.amazon.com/gp/customer-reviews/R1PSQWXUTUMLAD I will therefore keep this enclosure for another use with a machine having a more recent kernel (6.1) where this will not be an issue. I will test it with a version of CentOS 7 with a kernel version close to the current one to see if I encounter the same issues.
