Fix a bug in the NFS/TCP retransmission path. The bug was that earlier, if a request was retransmitted, we would do subsequent retransmits every 10 msecs. This can cause data corruption under moderate loads by reordering operations as seen by the client NFS attribute cache, and on the server side when the retransmission occurs after the original request has left the duplicate cache, since the operation will be committed for a second time. Further work on retransmission handling is needed (e.g. they are still being done sent too often since they are scaled by HZ, and the size of the dup cache is too small and easily overwhelmed on busy servers).
Wow. Nice catch. Robert N M Watson _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/cvs-all To unsubscribe, send any mail to "[EMAIL PROTECTED]"
