Span Disk Space
Hi all,
I am wondering if there is a way to use multiple OpenBSD (or FreeBSD...etc) machines disk space to represent one drive. Kind of like RAID except between machines. Using a package/port or software of some kind. :P I have not been very successful in my searches. Perhaps I am not using the right words. Code:
Example OpenBSD-1----partitionX(40G)----->| OpenBSD-2----partitionX(40G)----->|combined|-> OpenBSD-4-->partitionX(120G) OpenBSD-3----partitionX(40G)----->| Thanks! |

Hmm interesting. Thanks for the info. A friend also mentioned (since I made the post) iScsi, any thoughts on the difference?
Thanks! |

There are other alternatives. You could, I suppose mount your remote drives with NFS, and then use vnconfig(8) to create devices from files you create within them, then use ccd(4) or softraid(8) to combine them. I doubt you'd like the performance, and debugging a problem within all those layers is probably beyond the average admin.

Oh I understood iSCSI was available. It is on FreeBSD. Oh well as you state does not make much difference if it does not solve my problem.
Is AFS considered stable/reliable? How about expandable? Would I be able to "add" drives in the future to increase space? Thanks for your help. |

OpenBSD comes with an audited version of the arla project's AFS client, built in. I would consider that client stable, by its very nature (it is not the latest, of course). Public AFS servers are even listed in the Getting Releases page of the OpenBSD Project website.
Learn more about operating the client from $ man -k afs. The OpenAFS project server's roots are an open source branch of IBM's AFS, based on the original CMU/Transarc AFS server, granted to the public when IBM took AFS off the market. Stable? AFS dates from 1983. Start with the OpenAFS website. There is plenty of documentation there; the Administrator's guide will tell you what you need to know to architect a solution. |

Okay cool. I will play around with that and see how it goes.
Thanks for your help/info. |
