I've resolved it. It's the nfslock that doesn't function. Detailed as below:
1. I run "/etc/init.d/nfslock status" (client of nfs). It shows "lockd is running but rpc.statd is stopped. 2. Checked "man rpc.statd" and found that this daemon maintains stuff in /var/lib/nfs/statd/sm - but I found all the dirs/files in statd/ have strange owner/group attributes. 3. The strange owner attributes is the result of a clean installation of MD9.0 over the old system of MD8.2. The dirs/files keep the old uid of rpcuser, while the new installation assigns a new value as the uid of rpcuser. This inhibits rpc.statd from working. 4. Fixing the owner/group of them, and restarting nfslock, my mutt now works well as before. best regards, charlie On Wed, Oct 02, 2002 at 09:46:00PM +0800, Charles Jie wrote: > I've identified that the problem is at the nfs system, which now has > interoperability problem. > > pc1 exports ~/Mail with nfs-utils-0.3.3-3mdk > pc2 mounts it with nfs-utils-1.0.1-1mdk > > I use mutt on pc2, which complains "cannot monitor pc1" in syslog, and > "No locks available" in mutt. > > I'm studying nfs documents and plan to upgrade pc1's nfs to 1.0.1 - > though I'm not sure it's the very solution or not. > > If any advice available, please help and let me know asap.
