#Ephemeral storage aws full

If I get a chance I'll take a peek at the current implementation and see what might need to be done to get all the ephemerals attached by default.

I generally ping the ec2 metadata service to see what ephemeral drives are available to me and what their device names are before I subsequently auto raid0 them (in most cases). That's a bit tricky because they are different devices on different instance types.

I think the trick is making sure that you don't attach an ebs drive on one of the /dev/* devices that the ephemerals default to. I'd say that all the ephemerals available to a given instance type should always be available regardless of whether or not you intend to attach ebs drives on launch.

The case you're seeing is that if you provide a block_device configuration then you need to make sure the ephemerals are attached as well as the ebs drives. I think if you don't provide a block_device configuration that it'll default to providing all of the ephemerals to the instance. So I'll use the root of the drive, that drive won't be used for anything else.I've been thinking about this. I experimented with using SQL on a delayed start and having a start-up task to re-create the folders but that turned out to be a very (very, very, very) bad idea. This happens as you have to use the root of the drive as all folder structures will be lost too. Otherwise SQL changes the permissions on the drive and you'll lose access. The only thing I have found with this is not to specify the ephemeral storage as the location for tempdb on install. Yep, losing the data was my concern so I'm going to use the general provisioned storage (I want to use the bursting capabilities) for the data/logs and use the ephemeral storage for tempdb. For me that is win win combination.Īnd dont foret to do snapshots of instance and save them to the S3 buckets. If your company don't have enough money for that type of EBS,then use magnetic EBS and put your tempdb on Ephemeral storage (that will not help you with performance if you have log fragmentation and index problems). When you creating Amazon EC2 instance you can choose various types of EBS, and for your purpose you can choose EBS Provisioned IOPS (SSD).

One solution will be to made full recovery backup plan of your databases and put backups (FULL, DIFF and LOG) to Amazon S3 so you can do restore and recovery after instance restarting, but for me, you risk too much again. If you put your databases on Ephemeral storage on EC2 instance, then you will lose all your data on that storage after instance restarting.
