Hello guys,
I've a laptop which has a plain traditional HDD with 4K blocks.
And this laptop is fitted with an M.2 NGFF SSD device of 128GB. It is a
pity to use this SSD only as cache.
So I wonder if I can make a VG comprising the two devices (one PV per
device) and still retain the 4K blocks for the hard disk and the TRIM
and 512bytes sector size of the SSD.
And if the answer is yes, what should I be aware of ? Or what options
should i use during the pvcreate/vgcreate steps ?
Thanks for your help !
P.S. the HDD is GPT partitioned and the SSD is not so all options are
possible.
