atimes not updated through NFS
After upgrading an NFS server from kernel 2.6.12 to 2.6.23, the
atime of files is not updated any more when clients read them :
client$ ll -u --time-style +%Y-%m-%d_%H:%M:%S /nfsmnt/zz
-rw-r--r-- 1 xxx xxx 0 2007-12-21_14:58:11 /nfsmnt/zz
client$ md5sum /nfsmnt/zz
d41d8cd98f00b204e9800998ecf8427e /nfsmnt/zz
client$ date +%Y-%m-%d_%H:%M:%S
2007-12-21_15:00:28
client$ ll -u --time-style +%Y-%m-%d_%H:%M:%S /nfsmnt/zz
-rw-r--r-- 1 xxx xxx 0 2007-12-21_14:58:11 /nfsmnt/zz
Reading the file locally, i.e. on the NFS server, does update the
atime :
server$ ll -u --time-style +%Y-%m-%d_%H:%M:%S /nfsmnt/zz
-rw-r--r-- 1 xxx xxx 0 2007-12-21_14:58:11 /nfsmnt/zz
serveur$ md5sum /nfsmnt/zz
d41d8cd98f00b204e9800998ecf8427e /nfsmnt/zz
serveur$ date +%Y-%m-%d_%H:%M:%S
2007-12-21_15:04:00
serveur$ ll -u --time-style +%Y-%m-%d_%H:%M:%S /nfsmnt/zz
-rw-r--r-- 1 xxx xxx 0 2007-12-21_15:03:57 /nfsmnt/zz
/nfsmnt is mounted with options :
- server : rw,noexec,nosuid,nodev,nodiratime
- client : rw,user=root,nosuid,nodev,nodiratime,intr,rsize=8192,wsize=8192
Any ideas ?

If the Debian project published their users' email addresses,
we'd be getting spam. So I'm glad they don't.
