Distributed Storage Systems for Linux?

elambrecht asks: "We've got a _lot_ of data we'd like to archive and make sure it is accessible via the web 24/7. We've been using a NetApp for this, but that solution is just waaaay to expensive to scale. We want to move to using a cluster of Linux boxes that redundantly store and serve up the data. What are the best packages out there for this? GFS? MogileFS?"

AFS ??

[forsetti]

How about OpenAFS [openafs.org] ? It is sort of like NFS on steroids, with redundancy, scaling, cacheing, Kerberos-based security ... I've just started looking at it myself, but it seems pretty slick.

Ask Google

I'm sure they'd be happy to sell you something along the line of serving data....

Converting extra Windows(tm) workstation space?

[Dr.Dubious DDQ]

A barely-related subject - I've been wondering whether there's some way to collect the unused space on all the Windows workstations around here into a shared space for storage.

This is purely a speculative exercise, but I keep wondering if some combination of:

• Every Windows(tm) workstation "shares" an otherwise-empty subdirectory
• a Linux box creates and uses a "filesystem image" file of some kind ("loopback mount"-style image) stored on each share over SMB/CIFS
• Linux uses VFS to combine the individual virtual drives into a larger drive (or perhaps two identical-size virtual drives, which are then combined into a single software RAID 1 array?)
• Linux then shares this Rube-Goldbergian system as a Samba share...

Yes, I know it's kind of silly, and performance seems like it would be pretty pathetic, but the more I think about it, the more I want to see if I could actually do it (think pretty much the same mindset that the IP-over-carrier-pigeon guys had...)

Heck, it might conceivably actually WORK for a large-but-infrequently-accessed historical repository or something...

Or has someone already started some sort of "Virtual ATA-over-ethernet-from-a-file driver for Windows" project and spoiled my fun?...

If you want to try building it, I'd suggest you start with a nice high level method of creating linux based filesytems:

http://perlfs.sourceforge.net/ [sourceforge.net]

Build it first, optimize later.

FYI.. The multi-threaded filesystem version exists, I just haven't bundled it up pretty for distribution. Now someone needs to create a multi-threaded samba to share it out.
