I'm running VMware Workstation 12.5.1
, and am trying to haveSCSI0:0
as an SSD drive.
(I want to have the discard
mount option and fstrim /
work on ext4
and btrfs
.)
I added the following to my .vmx
file: scsi0:0.virtualSSD = 1
But in Linux (both Mint 17.2
and Manjaro 16.08
, /sys/block/sda/queue/rotational contains 1
, meaning it's not a spindle and platter disk.
However, smartctl -a /dev/sda
disagrees:

How do I get rotational
to be 0
(and thence get TRIM
working?)
If there is no solution here, where should I raise this upstream?

It seems that Vbox fixed the analogous issue 3 years ago:
