Hi I want to set up a small search cluster and I was wondering if raid is really needed since ES already has replication built in. Can I use multpile data paths in the ES config pointing to /mnt/disk1 ... /mnt/disk12 since disk cost is a premium or do you recommend to put the data on a raid volume ? What are the pro and cons of both. The first one would be similar to a hdfs setup. Would the number of replicas also be an option ? Which balance did you guys choose Regards Ronny -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

I use RAID0 on data folder for speed. If RAID fails, the whole node is decommissioned, there is one node per server. Replica level must be greater 0 or you will lose data sooner or later. Multiple data paths will just scatter files, probably over partitions, equal balancing over data paths is not guaranteed. And without RAID, scattering is not faster for read/write so you don;t have any advantage.
