I recently had a RAID failure on one of my Gluster replicas; luckily my
replica was ok, and I could re-sync all the data to the bad node's
bricks.  I used rsync to pre-seed the brick data, rather than having
Gluster's self-heal daemon try to figure it out.

It turns out I had way more files than I realized, which exposed some
problems with "traditional" rsync invocation.  I found some clever ways
to optimize the transfer and speed up the process, and wrote up my
experiences on my blog:
