Openfiler storage configuration
Posted on 2011-04-20
I have a configuration question that is more advisory in nature than how-to.
I have an Openfiler box that will be used for archival (non-live production) storage for an application that runs independently on four servers. Each server will have its own LUN to archive to. I know how to create partitions, volumes, and LUNs.
Since Openfiler doesn't do thin provisioning, I have to estimate up front how much space each server will need for archiving. However, It could turn out after putting the archive box in place that one server actually needs more space and another might need less, and I want to make resizing each server's space as painless as possible. (It's a new system and we have no history for how much space each server will need.)
So my question is, should I make the free disk space one big partition and one big volume and split the space up at the LUN level, or the volume level, or should I make each server's space separate from the partition level down?
My instincts are to do the former, throwing all the space (not including the OS) into a single partition and make that partition a single volume, which I then split up into four LUNs, one for each server. Any advice?
