| |
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 ?
