Hi. If I have 2 servers in AFR pair, each of them is both client and server, what is the option to make each server read/write from itself first?
I found an option: - *read-subvolume (default: none)* The value of this option must be the name of a subvolume. If given, all read operations are sent to only the specified subvolume, instead of being balanced across all subvolumes. But it seems it might actually lower the performance, deducted from here: "All operations that do not modify the file or directory are sent to all the subvolumes and the *first successful reply is returned to the application*. The read() system call (reading data from a file) is an exception. For read() calls, AFR tries to do *load balancing by sending all reads from a particular file to a particular server*. The read algorithm is also affected by the option read-subvolume; see below for details." Is it correct, and how this server is determined? Also, should I use the above option, or let GlsuterFS to decide for himself? Thanks!
