Hi, I was wondering how we control access to shared resources that are being utilized by different management servers at the same time.
For example: When a user attaches a volume (that's based on the SolidFire plug-in) to a VM, my plug-in looks at the CloudStack account that is requesting the operation. If this CloudStack account does not have a corresponding account on the SolidFire SAN, I must create one (there is a 1:1 mapping between CloudStack and SolidFire accounts). How can I protect against a situation where my plug-in is running in multiple management servers and performing this kind of operation at the same time (in other words, I don't want both instances of the plug-in to see no SolidFire account and then they each end up creating one, which breaks the 1:1 mapping between a CloudStack account and a SolidFire account)?
