[one-users] Files in /var/tmp/one/vmm/kvm/ disappear.

[Jaime Melis]

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
