Is this on the roadmap?
Not in the short term roadmap.
Of course, patches are welcome. It's mainly in VDSM.
I wonder if it'll work in NFS.
Y.
I don't think I ever replied to this, but I can confirm that in RHEV 3.6
it works with NFS.
Best regards,
Martijn.

New subject: iSCSI domain on 4kn drives
Good afternoon,
Exist a plan for a implementation of vdsm works with blocks in 4k?
Thanks.

Not yet.
If this is important to you, I suggest to open an ovirt bug and explain
your use case.
You can also get someone to implement this. Note that this will not be easy
change, there
is lost of code assuming 512 bytes block size.
The change also require changes in sanlock. Vdsm and sanlock must agree on
the block
size used for a storage domain.
Nir
Thanks.

David, do you know if 4k disks over NFS works for sanlock?

When using files, sanlock always does 512 byte i/o. This can be a problem
when there are 4k disks used under NFS. On disks, sanlock detects the
sector size (with libblkid) and uses 512/4k accordingly.
If vdsm knows when to use 4k i/o over files, I can add a sanlock flag that
vdsm can use to create 4k sanlock leases.
