OK, so we’ve been talking about NAS boxes at work. NAS (Network Attached Storage) is a simple server appliance. Plug this thing into the network and you’ve got an instant file server.
Problem is, they’re not that much less expensive than a file server, if at all.
Now, file serving isn’t a particularly CPU-intensive task. Put some decent-speed disks in a box with a simple CPU and some memory, running an embedded operating system, and you’ve got a NAS box, right? Sounds like a perfect job for Linux, right? And you can stuff a minimal Linux into 8 megs of disk space and save the overwhelming majority of your disk space for real work, right?
Well, I asked Charlie if I was completely crazy or not. He didn’t seem to think I was completely nuts. He did ask if I checked to see if anyone’s compiled Samba against uClibc, the alternative libc I was talking about using. I know one person has gotten Samba 2.2.8 to compile against a recent uClibc.
And I even found a project that downloads and compiles uClibc, TinyLogin and Busybox, essentially giving you a complete Linux environment in 600K of disk space, not counting the kernel. And it boots very quickly, even off a floppy. The only problem is that its tools are set up for the ancient Minix filesystem.
Charlie didn’t think running the enterprise on the Minix filesystem was one of my brighter ideas. Maybe I should be glad he didn’t tell me exactly what he was thinking.
Well, getting the system up and running with JFS or XFS probably won’t be much of a problem. Those filesystems are enterprise class if anything ever was.
I had difficulty getting Samba to compile though. I forget the exact error message I was getting.
I may have to opt for the uClibc-based Linux from Scratch, since it’s being actively maintained. That’ll be a bit more work.
I suspect it’s possible to get this combination of tools to work together though. I can’t imagine Quantum is running its Snap servers on Red Hat. I’m sure they’re using uClibc and other embedded tools in conjunction with Samba.
The question is how much more time I want to put into it. If indeed I ever get more time to put into it. The surprising thing to me is that nobody else has built and released this.
