I have a problem with NFS/AMD hangs for some filesystems in this large automounted network. (I reported this to questions earlier and got no responses). At first I though this might be related to these messages that went to the log the first time I started amd: noconn option exists, and was turned OFF! (May cause NFS hangs on some systems...) So I tried modifying /usr/src/usr.sbin/amd/include/config.h to play with the USE_CONNECTED_NFS_SOCKETS and USE_UNCONNECTED_NFS_SOCKETS. This doesn't seem to have any effect on the problem. What I have noticed is that these problems appear to be related to "deferred" mounts: bash-2.02# amq -s requests stale mount mount unmount deferred fhandles ok failed failed 10 0 176 0 0 bash-2.02# amq -s requests stale mount mount unmount deferred fhandles ok failed failed 12 0 176 0 0 In the code these are referred to as "dropped" mount requests. Can someone tell me what causes these and what I can do to fix this? -- Robert Withrow -- (+1 978 916 8256) BWithrow@BayNetworks.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
