I have an IBM system X3500 file server that has four hard drives installed. They are setup in a RAID 5 environment. I am running low on disk space and I want to be able to add additional drives to increase the storage capacity of this server.

I have other identical drives that I can add to this server. They are hot swappable. Is there a way for me to just add these drives and then have them added on to the RAID 5 configuration in such a way as I will be able to increase the storage capacity of this server without wiping the data and setup up the server from scratch.

Thanks for your input.

Depending on the RAID controller in the system, you can probably add the drives to the system and add them to your current array without an issue.   The problem is that your OS may not be able to see or use the new space as part of an existing partition, meaning that you'll have to back the data up and restore it to the new, larger partition.

You should look up any config guides for your RAID controller and follow the instructions they give you.  It will be different per array controller and per OS.

Note: If you really don't want to reinstall, you probably have the option of adding the disks to the current array, creating a partition, and mounting that partition in windows as a file system off the root of your existing drive.  Then you may want to move some large amount of data (My documents, for instance to that new, mounted drive.  Then just make sure that you use that new mount as your My Documents folder from then on.
