transcript from the upstream bug report : After doing an analysis of the code, most particularly lib/puppet/type/mount.rb it appears that the problem doesn’t lie with puppet but with cifs-utils.
When puppet does a ‘mount -o remount’, it triggers a bug in cifs-utils that makes a double entry in /etc/mtab. This is the commit of the fix for this bug : http://git.samba.org/?p=cifs- utils.git;a=commit;h=f46dd7661cfb87257c95081fc2071c934bfbbb16 “During a remount of a cifs filesystem, the mtab file is not properly updated, which leads to a doubled entry of the same filesystem in the /etc/mtab file. This patch adds a new function del_mtab() which is called before the add_mtab() in case the fs is being remounted.” A potential workaround is to use remounts => ‘false’ but a safer solution would be to get a version of cifs-utils higher than 5.3 : https://lists.samba.org/archive/samba/2012-January/165958.html To confirm this outside of puppet control, simply do the following : $ mount //sambahost/test /mnt/target $ mount -o remount /mnt/target $ df | grep target //sambahost/test 7033648 1278120 5402660 20% /mnt/target //sambahost/test 7033648 1278120 5402660 20% /mnt/target ** Package changed: puppet (Ubuntu) => cifs-utils (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to puppet in Ubuntu. https://bugs.launchpad.net/bugs/1144612 Title: puppet double mounts CIFS mounts To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cifs-utils/+bug/1144612/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
