Hi
I am using glusterfs now and reading the source code of the file read.Now I
encounter the following question:
1.What are the differences between the quick-read and io-cache in reading
files?
2.I find the writev(priv->fd, iov_out, count ) function in fuse_readv_cbk
function ,but I do not know its use.Does it write the content in iov_out to
priv->fd? Is the priv->fd is referenced to the file been reading? And I found
this would cause the communication between the client and the server and the
message transferred is large.Does it transfer the content in iov_out to the
server ? If this was so,where did the server store the content transferred?
Thank you!
