[Gluster-users] Newbee Question: GlusterFS on Compute Cluster?

[Adam Tygart]

James,

vrrp works fine, but from what I understand of the Gluster FUSE mount
process is that it will read the whole of the rrdns response and keep
trying to get the volfile from the others if the first server fails to
respond.
