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
add | tr -d ' ' fixes the problem
