Hi, I've a setup composed with 3 nodes(zodiac1, zodiac2, zodiac3)
Node config: 8 cores W5580 at 3.20GHz, 76 Go RAM, 40 To, infiniband mlx4_0
(20 Gb)
Gluster Version: 2.0.7
Kernel Linux 2.6.30 / Fuse 2.7.4
Config file:

Command on each server to start glusterfs:
glusterfs -f myreplica.vol /mnt/data/
The scenario that I use:
zodiac1 and zodiac2 are correctly synchronized. Once every thing is ok
for zodiac1 and zodiac2, I decide to start the zodiac3. I order to
synchronize it, I do on the
box ls -aLR /mnt/data. So the replication start but the transfer rate is
really slow: around 30 MB/s !
Have you an idea how can I increase this rate ?
Thank you.
