Re: [Gluster-users] How fill my volume for test?
Thank you Is it correct that there is not a standard way to fill a file system? If I fill my gluster volume with each of these methods, the result of performance test (speed of read, write, ...) are valid?

Re: [Gluster-users] Can not delete a volume

Re: [Gluster-users] How understand some code execute client side or server side?
Thank you very much, it is very helpful. I see the client graph also in /var/log/glusterfs/mnt-glusterfs.log when mount the file system. I think there is a tree structure between xlator (I had seen something in code like child and parent of each xlator), so just some of them are the point of connecting to server. I think xlator with type protocol/client is responsible for send request and get response from server. am I correct?
