This is my mount:
# mount|egrep -i 'sda|mapper'
/dev/mapper/vg_whitebox-lv_root on / type ext4
(rw,relatime,seclabel,barrier=1,data=""> /dev/sda1 on /boot type ext4 (rw,relatime,seclabel,barrier=1,data=""> /dev/mapper/vg_whitebox-lv_root on /tmp type ext4
(rw,relatime,seclabel,barrier=1,data=""> /dev/mapper/vg_whitebox-lv_root on /var/tmp type ext4
(rw,relatime,seclabel,barrier=1,data=""> /dev/mapper/vg_whitebox-lv_root on /home type ext4
(rw,relatime,seclabel,barrier=1,data="">
# swapon -s

I've selinux enabled, lvm and encrypted root and it works. It's a bit

Is the PV encrypted or the individual LVs. I have LUKS on top of LVM. Is your setup similar?
