We are setting up a 10 node ES cluster for one of our clients and will be loading/querying ES data in the terabytes. The current system was configured with a GPFS file system. I have some concerns with this related to network traffic. Does anyone have any experience supporting very large clusters running on GPFS or shared file systems. Is this a good idea? We do not have local storage available? Are there any other options? NFS/ etc... SOrry, I'm not a storage guy but would appreciate any help!
