So... this kinda applies to me too and I want to get some clarification: I
have the following setup

# gluster volume info

Volume Name: gv0
Type: Replicate
Volume ID: fc50d049-cebe-4a3f-82a6-748847226099
Status: Started
Number of Bricks: 1 x 3 = 3
Transport-type: tcp
Bricks:
Brick1: eapps-gluster01:/export/sdb1/gv0
Brick2: eapps-gluster02:/export/sdb1/gv0
Brick3: eapps-gluster03:/export/sdb1/gv0
Options Reconfigured:
diagnostics.count-fop-hits: on
diagnostics.latency-measurement: on
nfs.drc: off

eapps-gluster03 had a hard drive failure so I replaced it, formatted the
drive and now need gluster to be happy again. Gluster put a .glusterfs
folder in /export/sdb1/gv0 but nothing else has shown up and the brick is
offline. I read the docs on replacing a brick but seem to be missing
something and would appreciate some help. Thanks!
