Bug#824494: lvm2: should filter RPMB devices

[Steinar H. Gunderson]

Package: lvm2
Version: 2.02.153-1
Severity: minor

Hi,

I have an ARM-based device where I run LVM on /dev/mmcblk0p1;
however, during pvscan (which includes initramfs), it complains with:

  root at soldroid:~# pvscan
  /dev/mmcblk0rpmb: read failed after 0 of 4096 at 0: Input/output error
  /dev/mmcblk0rpmb: read failed after 0 of 4096 at 4128768: Input/output error
  /dev/mmcblk0rpmb: read failed after 0 of 4096 at 4186112: Input/output error
  /dev/mmcblk0rpmb: read failed after 0 of 4096 at 4096: Input/output error
  PV /dev/mmcblk0p2   VG odroid          lvm2 [58,00 GiB / 0    free]
  Total: 1 [58,00 GiB] / in use: 1 [58,00 GiB] / in no VG: 0 [0   ]

/dev/mmcblk0rpmb is the Replay Protected Memory Block, a special kind of
device which the OS normally does not have access to. I believe it should
simply be filtered by default; it does not make much sense to put an LVM
on it anyway.
