[Gluster-users] 3.1.x Setup: distributed replicated volumes across 6 servers, each with 24 drives

[Mark "Naoki" Rogers]

If I may ask, is there a reason you're not putting the 24 drives on each 
server into raid6/5 arrays and doing dist+rep over just:

clustr-01:/mnt/data clustr-02:/mnt/data clustr-03:/mnt/data
clustr-04:/mnt/data clustr-05:/mnt/data clustr-06:/mnt/data

But in answer to your question I think your config looks good and to 
mount you would just issue:

mount -t glusterfs clustr-0?:/dist-datastore/ /<mountpoint>
