[Bug 1129217] [NEW] rbd showmapped has trailing whitespace which break rbd monitor

[James Page]

Public bug reported:

Taken from rbd RA

find_rbd_dev() {
    local sedpat

    # Example output from "rbd showmapped" (tab separated):
    # id        pool    image   snap    device
    # 0         rbd     test    -       /dev/rbd0

    # Build the sed pattern, substituting "-" for the snapshot name if
    # it's unset
    sedpat="[0-9]\+[ \t]\+${OCF_RESKEY_pool}[ \t]\+${OCF_RESKEY_name}[ \t]\+${OCF_RESKEY_snap:--}[ \t]\+\(/dev/rbd[0-9]\+\)"

    # Run rbd showmapped, filter out the header line, then try to
    # extract the device name
    rbd showmapped | tail -n +2 | sed -n -e "s,$sedpat,\1,p"
}

rbd showmapped is outputing a trailing whitespace character at the end
of the block device which means that the monitor check can't find the
mapped block device
