Both client and server are 2.2-STABLE, with 3c905 100Mbps ethernet boards. Right now, for example, I have a netscape and am elm locked. If this helps, here's the output of a "ps -axlww | grep nfs" on the client: zeus::jonny [501] ps -axlww | grep nfs 0 112 1 0 2 0 236 0 accept IWs ?? 0:00.00 nfsd: master (nfsd) 0 114 112 0 2 0 228 0 nfsd IW ?? 0:00.00 nfsd: server (nfsd) 0 115 112 0 2 0 228 0 nfsd IW ?? 0:00.00 nfsd: server (nfsd) 0 116 112 0 2 0 228 0 nfsd IW ?? 0:00.00 nfsd: server (nfsd) 0 117 112 0 2 0 228 0 nfsd IW ?? 0:00.00 nfsd: server (nfsd) 0 127 1 0 -1 0 212 12 nfsrcv D ?? 0:00.09 nfsiod -n 8 0 128 1 0 -1 0 212 12 nfsrcv D ?? 0:00.06 nfsiod -n 8 0 129 1 0 -1 0 212 12 nfsrcv D ?? 0:00.03 nfsiod -n 8 0 130 1 0 2 0 212 12 sbwait D ?? 0:00.03 nfsiod -n 8 0 131 1 0 -1 0 212 12 nfsrcv D ?? 0:00.03 nfsiod -n 8 0 132 1 0 -1 0 212 12 nfsrcv D ?? 0:00.02 nfsiod -n 8 0 133 1 0 -1 0 212 12 nfsrcv D ?? 0:00.02 nfsiod -n 8 0 134 1 0 -1 0 212 12 nfsrcv D ?? 0:00.01 nfsiod -n 8 100 410 1 0 -6 0 7048 4304 nfsaio D v1 0:10.64 /usr/local/lib/netscape/netscape.bin zeus::jonny [502] The relevant fstab options are as follows: gaia:/ /gaia nfs rw,soft,intr,bg,nfsv2,dumbtimer 0 0 gaia:/usr /gaia/usr nfs rw,soft,intr,bg,nfsv2,dumbtimer 0 0 gaia:/var /gaia/var nfs rw,soft,intr,bg,nfsv2,dumbtimer 0 0 gaia:/extra /gaia/extra nfs rw,soft,intr,bg,nfsv2,dumbtimer 0 0 Using option "tcp" helps a lot, but if the server reboots, the client does not reconect. "nfsv2" and "dumbtimer" seem to have helped, but did not solve the problem. Is there anything I can do to help debug this ?
