[Gluster-users] replica count documentation

This is what I thought as well. But at what kind of consistency level? How
many replicas is the file written to before returning to the client
application? Assuming I have my replica count set to 2 with my 2 brick
setup, it sure isn't strict. I've waited 15 mins after the write to one
brick has finished before it was actually synced up on the second.


Try volume info command to see the replicas.


I'm not so much trying to "see the replicas" as get the number of replicas.
My understanding is that replica != brick, so where is the number of
replicas in the output below?

# gluster volume info virt-isos

Volume Name: virt-isos
Type: Replicate
Status: Started
Number of Bricks: 2
Transport-type: tcp
Bricks:
Brick1: 192.168.0.150:/virt-isos
Brick2: 192.168.0.151:/virt-isos
virt1:~#
