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!
