Dear All, Is it possible to decommission a disc from nodes? is it possible to stop indexing/storing data on particular disc?.

If you are using multiple data paths and you replace a disk, you will lose all data on that node. "Data can be saved to multiple directories, and if each directory is mounted on a different hard drive, this is a simple and effective way to set up a software RAID 0.

Are the disks not the same size? You will need to make sure the shards that this node has are on other nodes, or move shards to other nodes, then replace the disk.
