hi, we are going to setup elasticsearch server with 20 SSD on it. but I am not sure how we gonna group those SSDs.
i read some material it says setup as RAID 0. Shall I group all 20 SSD into one file system or should separate each disk as one file system? our sysadmin says not suggest to group all SSD into one file system as one SSD dies it will affect the whole file system.
below are my questions if i setup separately as follows:
- how I should configure the path.data in elasticsearch conf?
- how to make sure the shards (especially replica) are distributed on different disk evenly instead of 1 disk?
