Hello, I've just setup Scalr so that I can get some highly available MySQL servers up on EC2. I am new, and looking for any documentation or info about Scalr, and I can't hardly find anything, so if you know of any, please point me in the right direction.
In the mean time, I have a few questions that would really help me out if you could answer. 1. When setting up a mysqllvm farm, if I enable "Bundle and save mysql data snapshot every 48hrs" Will the database be unavailable while the bundle is taking place? If so, how long will it be unavailable? 2. If I enable "Periodically backup databases every 15 mins" will the backup cause any interruption to the database service? If so how long, and what type of backup is being performed (an export?) and where is it stored? 3. If under storage engine in the MySQL Settings tab I select EBS, do I need to also specify to attach an empty EBS volume under the EBS tab? Or will doing that create a second EBS drive? 4. When I build a farm I have to select an east or west coast region. How can I put a slave in a different zone for redundancy? 5. In the information I could find, Scalr uses a single master multi slave system for MySQL -- but DNS round robins, so that write could go to any of the instances, not just the master. This seems more like a master-master setup. Which one is it? And is there some type of locking mechanism that prevents errors, such as a primary key being issued to two different instances at the same time? Thanks in advance for you help, Cole --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "scalr-discuss" group.
