Personal Data at Work
There’s plenty of information and talk around about the issues of allowing company data onto a personal device, but what about personal data on a work device? More and more of our personal data is stored in “cloud” services like Gmail and Evernote that we access from work computers and company controlled accounts. In the time of buzzwords like “BYOD” business is rightly concerned about their data being on that tablet of yours that you managed to connect to the company wireless. They want to make sure that the correct level of security protects their data – especially things like email that almost everyone accesses from their smart phone, tablet or even web kiosk. Personal devices have proliferated the work place since they became cheaper, smarter and cooler to have than the company provided devices. Right now business is just starting to catch on and recognise that things are changing and that not everything can be restricted or dictated like they used to be.

Drbd Forcing a Full Resync in a Split Brain Situation
I have a DRBD setup similar to an old post that’s being used between two Ubuntu servers hosting MySQL. Every few months though the pair goes into a split-brain situation where the secondary can’t see the primary and refuses to reconnect. Users are unaffected as the primary is still working fine, but the HA is lost. After trying a few different combinations of commands this is what seems to work best for me and cause the quickest recovery. I’m only dealing with a 10GB device so a full sync takes about 10min. If you’re using DRBD for a much larger device, make sure you consider the sync time before doing this.
