My FC6 desktop client becomes unresponsive every 15-30 seconds for 5-15 seconds during long NFS write operations. My installation is up-to-date as of this morning. This occurs with both an FC4 NFS server and another NFS server I have running nfs-utils. I can't see any issues in nfsstat on the client: [root@ratbert nick]# /usr/sbin/nfsstat --nfs Client nfs v3: null getattr setattr lookup access readlink 0 0% 39 0% 3 0% 16 0% 30 0% 0 0% read write create mkdir symlink mknod 0 0% 476675 99% 2 0% 0 0% 0 0% 0 0% remove rmdir rename link readdir readdirplus 3 0% 0 0% 0 0% 0 0% 0 0% 223 0% fsstat fsinfo pathconf commit 5 0% 10 0% 0 0% 376 0% Client nfs v4: null read write commit open open_conf 0 0% 0 0% 0 0% 0 0% 0 0% 0 0% open_noat open_dgrd close setattr fsinfo renew 0 0% 0 0% 0 0% 0 0% 0 0% 0 0% setclntid confirm lock lockt locku access 0 0% 0 0% 0 0% 0 0% 0 0% 0 0% getattr lookup lookup_root remove rename link 0 0% 0 0% 0 0% 0 0% 0 0% 0 0% symlink create pathconf statfs readlink readdir 0 0% 0 0% 0 0% 0 0% 0 0% 0 0% server_caps delegreturn 0 0% 0 0% On the server I see nothing wrong: # cat /proc/net/snmp Ip: Forwarding DefaultTTL InReceives InHdrErrors InAddrErrors ForwDatagrams InUnknownProtos InDiscards InDelivers OutRequests OutDiscards OutNoRoutes ReasmTimeout ReasmReqds ReasmOKs ReasmFails FragOKs FragFails FragCreates Ip: 2 64 2033141 0 0 0 0 0 2033109 1264641 0 0 0 0 0 0 0 0 0 Icmp: InMsgs InErrors InDestUnreachs InTimeExcds InParmProbs InSrcQuenchs InRedirects InEchos InEchoReps InTimestamps InTimestampReps InAddrMasks InAddrMaskReps OutMsgs OutErrors OutDestUnreachs OutTimeExcds OutParmProbs OutSrcQuenchs OutRedirects OutEchos OutEchoReps OutTimestamps OutTimestampReps OutAddrMasks OutAddrMaskReps Icmp: 5 0 5 0 0 0 0 0 0 0 0 0 0 21 0 21 0 0 0 0 0 0 0 0 0 0 Tcp: RtoAlgorithm RtoMin RtoMax MaxConn ActiveOpens PassiveOpens AttemptFails EstabResets CurrEstab InSegs OutSegs RetransSegs InErrs OutRsts Tcp: 1 200 120000 -1 2 205 0 0 1 2031363 1263636 2 0 0 Udp: InDatagrams NoPorts InErrors OutDatagrams Udp: 1700 17 0 993 Any ideas what I can look at? I need to get NFS running for home directories, but the machine using it become unusable when copying big files around. Thanks, Nick.
