      Well, I've gotten myself into trouble using ChatGPT. I'm sure this will read like a horror novel for you. This started with my newer USB HDD enclosure. Things were working fine for a while, and then I started to see random disconnects. All the disks would drop from xcp-ng simultaneously after x mins/hours. Here is a dmesg from xcp-ng displaying what happened:

      So my first steps were to disconnect other disks, install updates, and reboot. I left it like that for about 48 hours and then the disks disconnected again.

      ChatGPT then had me make a quirk entry in XCP-ng disabling UAS
      nano /etc/modprobe.d/disable_uas.conf

      options usb-storage quirks=174c:55aa:u

      dracut -f
      Reboot xcp-ng

      ChatGPT then told me:

      • On XCP-ng (CentOS-based, older kernel), this syntax is not enough:
      • It will only apply if usb-storage loads before uas, and on your system uas loads earlier, so the quirk is ignored.
      • We need to explicitly force usb-storage to claim the device before uas is even allowed to load.

      nano /etc/modprobe.d/blacklist_uas_174c_55aa.conf

      blocklist uas

      dracut -f
      reboot host

      This again did nothing.

      ChatGPT then said:

      • Correct Fix for XCP-ng: Update the bootloader's initrd
      [13:36 xcp-ng-3 ~]# cat /boot/efi/EFI/xenserver/grub.cfg | grep initrd
module2 /boot/initrd-4.19-xen.img
module2 /boot/initrd-4.19-xen.img
module2 /boot/initrd-4.19-xen.img
module2 /boot/initrd-fallback.img
module2 /boot/initrd-fallback.img

      and then:

      dracut -f /boot/initrd-4.19-xen.img 4.19-xen

      After this, upon reboot I was booting to a dracut command prompt. The issue here was that apparently USB had been fully disabled, so my keyboard is fully disabled.

      I probably should have posted on here then, but I didn't. At ChatGPT's suggested, I booted the device with the install media and ran shell. After a bit of work, here's what we did that seemed to be working:

      mkdir -p /mnt/root
mount /dev/md127p1 /mnt/root
mount /dev/md127p4 /mnt/root/boot/efi
mount --bind /proc /mnt/root/proc
mount --bind /sys /mnt/root/sys
mount --bind /dev /mnt/root/dev
chroot /mnt/root

      From chroot, I used the following to remove any offending modprobe.d files

      ls -l /etc/modprobe.d

      Followed by

      dracut --regenerate-all --force

      I then umounted everything, exited chroot, and rebooted.

      After a reboot the issue persisted. So we tried dracut with the verbose flag (NOTE: this is OCR from a photo, so there are typos and weirdness):

      sh-4.2# dracut -force -verbose /boot/initranfs-S(uname -r).img $(uname -r)

      ChatGPT's solutions are escalating, and getting downright dangerous at this point. It would be great to have a (preferably sympathetic) human help me out.

      So my issue is still that:

      • I boot to Dracut with a disabled keyboard
      • I can boot install media to shell, but something isn't working right

      Other things that I didn't mention yet that may or may not be relevent:

      • the enclosure is connected with a USB-C cable to a USB-C input
      • the enclosure hosts 4 disks
      • Other disks/enclosures were not experiencing the disconnect issue
      • The enclosure was actually working fine until a few days after I troubleshot/resolved an issue with one disk having slow transfer speeds. I switched the enclosure from USB-A to USB-C and also disabled spindown for the affected disk in the enclosure. Disabling spindown was done at the VM level, so I didn't mention it above.

        @nuentes Hello,

        Following an IA seem to be dangerous already, no need for Skynet 😆

        There is a documentation part about regenerating the initrd: https://docs.xcp-ng.org/troubleshooting/common-problems/#initrd-is-missing-after-an-update

        You can likely used what you did above to mount the XCP-ng FS and then regenerate the initrd using this command.
        It's not an initramfs that you need to generate but a initrd 🙂

          @dthenot Thanks for getting back to me.

          Yes, it seems we still have time to prepare for the robot uprising

          I did boot from the initrd fallback before, and ChatGPT walked me through hosing that one as well.

          I ran the command from that doc as verbose.

          alt text

          I ran the exact command a 2nd time as:

          dracut -f --verbose /boot/initrd-4.19-xen.img 4.19-xen

          No change. Boot to dracut with the keyboard not working. I've tried multiple kernels.
