Hi Ana,
There is no documentation because this is not something that is common. Assuming you are using
SolrCloud and that you don’t want any downtime. What you could do is set up new Solr node
on the same box but configure it to use this new disk. After it is set, you use ADDREPLICA
and REMOVEREPLICA to “move” replicas from one to another and shut down the old node.

If you can afford downtime, you can simply set up new Solr to use new disk, create empty collections
and copy indices from one disk to another.
