If it is only the brick that is faulty on the bad node, but everything 
else is fine, like glusterd running, the node being a part of the 
trusted storage pool etc,  you could just kill the brick first and do 
step-13 in "10.6.2. Replacing a Host Machine with the Same Hostname", 
(the mkdir of non-existent dir, followed by setfattr of non-existent 
key) of 
https://access.redhat.com/documentation/en-US/Red_Hat_Storage/3.1/pdf/Administration_Guide/Red_Hat_Storage-3.1-Administration_Guide-en-US.pdf, 
then restart the brick by restarting glusterd on that node. Read 10.5 
and 10.6 sections in the doc to get a better understanding of replacing 
bricks.
