I have spent some time understanding the NQNFS code and have two questions to ask: (1) People say we can not do write-behind on the NFS server side. Does this mean all vnode I/O must be performed with IO_SYNC (or other similar) flag set on the server side when the I/O is done on behalf of a NFS client? (2) NQNFS uses the concept of write slack time. What will happen if a NFS client fails to write the modified buffer back to the server's stable storage within that slack time? Will the late write request be discarded by the server? Any help is appreciated. -Zhihui To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
