Hello list
I am having problems with my GlusterFS setup (git version). I have two systems
acting as GlusterFS server and client on the same time. I used AFR on the server
side and the client used RRDNS to connect to the servers. But after having data
loss with that setup I moved to client side AFR. The result however is the same.
I loose data. I copy one file to the target directory and everything seams to be
okay. But then for no reason the file on one of the clients just has 0 bytes
size and after some while the other client has as well the file with 0 byte
size.
Here the used configuration files:
