I have not yet received any feedback on this issue. Can someone please take a look into this? Seems like updating mtime on the folder from different client is causes nocto to stop working on a mount (or a subfolder of the mount) client1: mount -t nfs -o vers=3,noatime,nodiratime,noacl,ac,sharecache,lookupcache=all,nocto 10.30.0.11/foo /mnt while true; do time cat /mnt/linux-headers/*.h >/dev/null ; done real 0m1.037s user 0m0.008s sys 0m0.088s real 0m0.021s user 0m0.008s sys 0m0.008s [...] client2: same mount, touch /mnt/linux-headers What happends (after few secs) is client1 times goes to over a sec and stays there for infinity. a -o remount (run a few times) solves problem (until client2 touches a folder again..) -- Bj(/)rnar -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
