Uwe Schindler commented on LUCENE-6614:
---------------------------------------
[~steve_rowe]: Can you also test the patch if it returns spins=false for the
NVMe device on your machine.
By the way: Mike and I had also problems with booting from NVMe, but in his
case the BIOS did not detect it and was not able to boot from it. The Ubuntu
installer wans able to handle the device name, but we were not able to boot. I
helped him to find the fix (my experience with all this kind of shit in earlier
days when I had a DEC Alpha Machine with SATA disks) was to use an
(Elastic-)USB stick and make the Ubuntu installer mount it as /boot, so grub
and kernel went onto it. By that the kernel and Grub bootloader are loaded from
the USB drive and it chains to boot with NVMe as root mount. Also Ubuntu kernel
updates worked perfectly, because of /boot as mount point.

> NVMe is the faster (than AHCI) protocol for newer SSDs that plug into the
> PCIE bus.
> I just built a new beast box with one of these drives, and the partition is
> named {{/dev/nvme0n1p1}} while the device is {{/dev/nvme0n1}} by Linux - this
> also appears in /sys/block with rotational=0.
> I think [~steve_rowe] also has an NVME drive ...
> [~thetaphi] (who got the box working for me: thank you!!!) has ideas on how
> to fix it!
