Uwe Schindler updated LUCENE-6614:
----------------------------------
Attachment: LUCENE-6614.patch
Here is a quick patch, completely untested (no Linux available at the moment).
The idea:
Instead of stripping off digits from the partition name and do exists() over
and over, I think the better solution is to take what's already there and not
do brute force. This patch lists the directory contents of /sys/block and for
each file name it encounters, it checks if the partition we got from mountpoint
starts with the /sys/block device name. Of course there can be overlap, so the
largest patch is taken.
Maybe Mike has some time to test, I will do this later in my VirtualBOX. I also
added a test for this type of device naming.

> 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/nsme0n1}} 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!
