Based on my (mis)understanding of what you're describing, it sounds like 
you want something like Andrew FS (AFS) or Coda FS (Coda).  I'm sure 
there are other file systems that have come to fruition in that family 
(I can't remember the name).


I have used ceph, but its minimum requirements are way to heavy for 
a small network,moosefs looks to be similar and as dedicated storage, 
that's not what I am after.


I'm not familiar enough with any of the above to comment on the 
similarities or differences.

[gentoo-user] OT: aggregating filesystem

Is there such a thing as a linux network filesystem that aggregates
storage across a few machines?  I am not talking about dedicated chunk
servers and the like, but something that can make available a the unused
space on a number of machines (desktops, servers, ...) by aggregating
and making available the space to the network. Is afs (or coda?) what I
am after?

I haven't been able to use Gentoo directly, but I have used Linux on
Power on GCC's servers. There's nothing terribly abnormal, though
there's a lot of interesting FPU modes.

You should use ppc64le. This complicates things when compiling, and is
a minor issue for some other compilers, who do not support multilib in
a way that makes it possible to build a ppc64le toolchain from a ppc64
toolchain. You may need to set up tools on a computer of another
architecture, or get prebuilt tools from GCC.

They are expensive, but one day, if the Lord decides to bless me, I may own one.

[gentoo-user] Is anyone using a TALOS 2 or any OpenPOWER machine?

[taii...@gmx.com]

I am of curious as to peoples experiences with OpenPOWER machines and 
gentoo - is it as simple as using the ppc64 arch iso instead of x86_64?
If anyone uses it for a workstation, what apps do you have? is there 
anything normal missing? (ie: that one would have on an x86_64 workstation)


I noticed that gentoo only has big endian isos instead of little endian 
and I am also wondering what this means for software availability as I 
have never heard of endianness before a few months ago.

It's completely useless today. Unless you have some binaries from 15 years
ago or so that you're still using, which I assume is not the case.




Thank you.
