Gluster's replication is implemented as "copy on write". That
means that your client writes to both copies of the file at the same time. All
file operations, including adding and removing locks are done synchronously.
There is no possibility of replication partners getting "out of sync".
Thanks,
Craig

Subject: [Gluster-users] Concurrency Access ?
Hello !
I've some question about this problem..
Situation :
I've two site with each time glustefs server installed (And replication
between both server)
But, Two site are active with read and write operation..
What happens when both site write in the same time the same data.. ?
There's no lock to say "" HEY i'm writing, don't touch
this file"" no ?
So.. Data may be corrupt ?
Or i'm crazy and just don't understand.. : ) please need some help : )
