Title:
  [UBUNTU] Avoid creation of mixed-blocksize PV on LVM volume groups

Status in Ubuntu on IBM z Systems:
  Triaged
Status in lvm2 package in Ubuntu:
  New

Bug description:
  Default block-size of a file-system seems to be dependent on the volume-size.
  Big volume (at least ext4) does have 4k blk-size, even the underlying device with a smaller physical blk-size.

  The patch, avoiding define mixed-sized volume groups is now upstream
  in the master branch of LVM2
  https://sourceware.org/git/?p=lvm2.git;a=commit;h=0404539edb25e4a9d3456bb3e6b402aa2767af6b

  Using this patch within the distribution is for sanity reasons.
