Ceph » ceph-volume

This is a regression introduced by [1]

When a logical partition is present on the host then the lsblk output displays the parent/child relationship between the device and the partition via the `└─` character.

# lsblk --paths --output=NAME --noheadings
/dev/sda
└─/dev/sda1
/dev/sdb
/dev/sdc
/dev/sdd

Due to this output, the `ceph-volume raw list` command is failing (in fact, the command returns zero but stderr shows the lsblk error)

# ceph-volume raw list
{}
 stderr: lsblk: `-/dev/sda1: not a block device
