Additionally, to reduce IO contention on the disks for etcd, you can use a dedicated device for the data and wal directory. Based on etcd best practices, mirroring RAID configurations are unnecessary because etcd replicates data between the nodes in the cluster. You can use stripping RAID configurations to increase available IOPS. -To implement this solution in an RKE cluster, the `/var/lib/etcd/data` and `/var/lib/etc/wal` directories will need to have disks mounted and formatted on the underlying host. In the `extra_args` directive of the `etcd` service, you must include the `wal_dir` directory. Without specifying the `wal_dir`, etcd process will try to manipulate the underlying `wal` mount with insufficient permissions. +To implement this solution in an RKE cluster, the `/var/lib/etcd/data` and `/var/lib/etcd/wal` directories will need to have disks mounted and formatted on the underlying host.
