Re: [one-users] Files in /var/tmp/one/vmm/kvm/ disappear.
Hello Richard, I'm not sure if this is related to OpenNebula, maybe there's some other daemon who's removing those files. Just to be sure it isn't OpenNebula, I suggest you audit that file to discover the PID of the process removing it: # install audit package # start the auditd daemon $ auditctl -w /var/tmp/one/vmm/kvm/deploy -p war -k opennebula_remotes wait for the unwanted delete to take place (you'll find the log in /var/log/audit/audit.log) Once you're finished do $ auditctl -W /var/tmp/one/vmm/kvm/deploy -p war -k opennebula_remotes # shut down the auditd daemon Regards, Jaime On Thu, Mar 8, 2012 at 11:37 PM, richard -rw- weinberger < richard.weinber...@gmail.com> wrote: > Hi! > > I see a very strange issue on OpenNebula 3.0. > From time to time most files n /var/tmp/one/vmm/kvm/ disappear on all my > hosts. > > $ ls /var/tmp/one/vmm/kvm/ > kvmrc poll > > vs. > > $ ls /var/tmp/one/vmm/kvm/ > cancel deploy kvmrc migrate migrate_local poll poll_ganglia > restore save shutdown > > After a "onehost sync" all files come back. > But it takes some time and is very annoying. > > Is this a known bug? > /var/tmp/one is on each host a regular directory on top of ext4. > > -- > Thanks, > //richard > ___ > Users mailing list > Users@lists.opennebula.org > http://lists.opennebula.org/listinfo.cgi/users-opennebula.org > -- Jaime Melis Project Engineer OpenNebula - The Open Source Toolkit for Cloud Computing www.OpenNebula.org | jme...@opennebula.org ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org
