[Gluster-users] are they no longer syncing?

I have a two node cluster setup with iscsi using the image files that 
are stored on the gluster cluster as LUNs. They do appear to be syncing, 
but I have a few questions and I appreciate any help you can give me. 
Thanks for your time!

1) Why does the second brick show as N for online?
2) Why is the healer daemon shown as NA? How can I correct that if it 
needs to be corrected?
3) Should i really be mounting the gluster volumes on each gluster node 
for iscsi access or should i be accessing /var/gluster-storage directly?
4) If i only have about 72GB of files stored in gluster, why is each 
gluster host about 155GB? Are their duplicates stored somewhere and why?
