Hi, all
I'm new to gluster, and still trying to figure out whether it's suitable
for my project. Gluster has built-in failover support, which is very
great, but after reading the user manual, I found that the split-brain
problem, one of the most difficult problems of HA design, wasn't
mentioned at all.
Does gluster have such problem during failover ? If does, how to avoid
data corruption ?
Yes, split-brains are possible. Quorum configuration can be performed to
avoid chances of split-brain. Details on client quorum can be found at
[1], [2] and server quorum can be found at [3].
