Yes, disk alignment is only needed as the LVM stack cannot get the details of
the HW Raids.In your case , use the default 256k as per documentation.

Dear Strahil,
Thank you very much for pointing me to the RedHat documentation. I wasn't aware
of it and it is much more detailed. I will have to read it carefully.
Now as I have a single disk (no RAID) based on that documentation I understand
that I should use a data alignment value of 256kB.
Have you checked this page:
https://access.redhat.com/documentation/en-us/red_hat_gluster_storage/3.5/html/administration_guide/brick_configuration
?
The alignment depends on the HW raid stripe unit size.

pvcreate. The documentation
