On my system, I only see the singe "timestamps" file in /var/lib/NetworkManager. Do you have any active systems connections or VPNs active at the same time? That would explain the multiple timestamps files?
>From a cursory glance, these timestamps record an active connection's last-used time so that if a disconnect occurs, NetworkManager will automatically re-connect to the right network. Re: the fsync, my guess is removing it at worse case would cause NetworkManager to hiccup and try to connect to the wrong network if the last-used timestamp didn't actually hit the disk and the system was put to sleep/rebooted... -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/913856 Title: NetworkManager periodically writes to the disk causing wakeups Status in “network-manager” package in Ubuntu: New Bug description: Network Manager is periocially creating dirty pages that are being written back to disk and causing uncessary drive wakeups. Using SystemTap I was able to observe the following dirty pages being created on the following files 0 795 1 NetworkManager sda1 D Mon Dec 19 13:54:50 2011 timestamps 0 795 1 NetworkManager sda1 D Mon Dec 19 13:54:50 2011 timestamps.096F6V 0 795 1 NetworkManager sda1 D Mon Dec 19 13:54:50 2011 0 795 1 NetworkManager sda1 D Mon Dec 19 13:54:50 2011 timestamps.5RWD6V ..and this occurs regulary every 5 minutes. Can we either reduce the frequency of these writes or better still only write the updates when really necessary (e.g. when we close NetworkManager or the user interacts with NetworkManager which requires us to really write data back to disk).
