iSCSI does not control when files show up. It depends on caching on the target/initiator and how the filesystems work. How are you detecting the files on the target side? Are you also mounting the FS on the target side? If you are seeing the data get copied on the wire but do not see the file on the FS mounted on the target side then it probably depends on how your target is caching the data. iSCSI the protocol has nothing to do with this, and the iscsi initiator has not much control over there (if your target supports it you can control the caching using some tools like in sg utils). Are you just saying that the data is not showing up on the target for 10 to 20 seconds, how are you determining this? Are you watching it with wireshark or tcpdump? It could depend on the caching in your app or FS. If you are just saying the actual copy is taking 10 or 20 seconds then you need to provide some data about the file size and hw being used. -- You received this message because you are subscribed to the Google Groups "open-iscsi" group.
