I can't figure out how this would cause issues except via extreme side-channels for negligible data. The monitor freely advertises the FSID when you poke at it, so anybody who has access to a network can find it trivially. So all we're really looking at is if there's some way to correlate publicly-accessible data that includes an FSID but is otherwise considered private. And telemetry would be the way to do that. What sort of use case are you thinking of? That would let us try and come up with more informed attacks on it. :) -Greg On Wed, Mar 2, 2022 at 9:05 AM Blaine Gardner <brgardne@xxxxxxxxxx> wrote: > > Hi all, > > Is the FSID of a Ceph cluster considered sensitive information?
