Verify that changelog reading is enabled.
On Lustre 2: Default mode is: --read-log --purge --rmdir

But, as you specified '--purge', I'm not sure RBH is still enabling its 
default options.
Look at your RBH logs.

Or, run "robinhood -d --readlog --purge"

Mobile security can be enabling, not merely restricting. Employees who
bring their own devices (BYOD) to work are irked by the imposition of MDM
restrictions. Mobile Device Manager Plus allows you to control only the
apps on BYO-devices by containerizing them, leaving personal data untouched!
