Hi All My nodes have 3 disks. 1) I have installed on one 2) I have mentioned the second for storing VM data These two are done during installation. 3) I added the other via rancher in the node page. Now my questions 1) 1st disk which is used for installation get used for any purpose other than serving the OS 2) VM data, is this where harvester longhorn and longhorn stores the data? 3) how I can use the 3rd disks which I attached 4) in Harvester network storage is the only option ? My original plan before trying harvester was to 1st disk only for OS 2nd disk for local storage 3rd disk for network storage

please correct if my understanding is wrong.. you have a multiple-node harvester cluster, and each node has 3 disks?
you have configured an additional disk during the install / post install for use by longhorn?

Yes, all nodes have three disks. During installation, it asked for 2 disks, and after installation, in Rancher, I chose the node and then went to the storage tab and attached the 3rd disk.

by default the 3rd disk will be used with longhorn.. and used for workloads, unless you want to use storage tags, and then create a custom storage class.. https://docs.harvesterhci.io/v1.1/host/#storage-tags
this way you can have different disk types for serving different workload types
with regards to additional storage providers, we are working on that and in 1.2.0 we are planning to open up harvester to use 3rd party CSI's https://github.com/harvester/harvester/issues/2405
