    Description

      In 7.0, LUKS is certified for disk encryption on Linux hosts. We need to capture which clusters have deployed it.  You can use lsblk to list the block devices, it doesn't require sudo access. 

      $ lsblk -fsa
      NAME FSTYPE LABEL UUID MOUNTPOINT
      loop1
      loop2
      loop3
      loop4
      loop5
      loop6
      loop7
      sda1 ext4 2a46d37a-28cd-4810-8726-09b1f6c030b0 /boot
      └─sda
      sda2 swap 451b6d8c-3607-4df5-9104-38f4cd7f7d8e [SWAP]
      └─sda
      sda3 ext4 82a47a78-4e2f-4c0b-8993-dcfc91bc9bcf /
      └─sda
      crypt_dsk ext3 968c76ab-a34f-4533-a55c-135bc5f0f67f /media/crypto
      └─loop0 crypto_LUKS 2fd131a3-076d-4cbd-bfed-5c6325f2872e

      Ideally grabbing additional detailed LUKS info with (sudo cryptsetup status /dev/xxx) would also be nice, as it lists the Type, Cipher, Keysize but I appreciate it's a bit more involved to implement.   As a FYI, (sudo dmsetup ls --target crypt) lists the LUKS devices that use device mapper.
