Hi,
I'm trying glusterfs-3.1.0beta in my environment and have following questions.
1) Can I start/stop volumes from any servers?
I have 5 servers and a volume 'vol1'on them.
It seems that 'gluster volume start vol1' returns immediately at
head-001(10.200.20.1) but does not return at another servers.
[root at head-001 ~]# gluster peer status
Number of Peers: 4
hostname:10.200.20.2, uuid:f651680b-3b0a-4675-b4b6-c8d8e62e741c, state:3 (connected)
hostname:10.200.20.3, uuid:e2897fcb-320a-4aee-abd1-78726855c241, state:3 (connected)
hostname:10.200.20.4, uuid:6c8f8d61-ed37-4d87-b1ef-594ffacd1a94, state:3 (connected)
hostname:10.200.20.5, uuid:ac1a1b49-e8c8-4fbd-bafa-4f459f7bc96f, state:3 (connected)
[root at head-001 ~]# gluster volume info
Volume Name: vol1
Type: Distribute
Status: Started
Number of Bricks: 5
Transport-type: tcp
Bricks:
Brick1: 10.200.20.1:/export
Brick2: 10.200.20.2:/export
Brick3: 10.200.20.3:/export
Brick4: 10.200.20.4:/export
Brick5: 10.200.20.5:/export
2) Can I expect same or higher I/O performance lower cpu usage compare to 3.0.5 ?
bonnie++ results (3.1.0beta vs. 3.0.5) in the same 5 servers:

3) When and what keys should I change the value? and how should I review the current values ?
volume set <VOLNAME> <KEY> <VALUE> - set options for volume <VOLNAME>
Thanks,
