Many thanks to all how have responded so far.  Based on the replies 
we're now looking at LizardFS, which I *thought* I had previously 
brought up, but if I did it hadn't stuck.  This time it did.

As for Oracle Linux, we hate it with a burning passion, but have zero 
choice; that's what it has to be.  :-(

Keith, good to know about activity, it looks quite bad on the wikipedia 
page where MooseFS looks good.

Will, thanks for the note about Chrony, I suspect any/all of these will 
be sensitive there so I'll make sure that is specced in.  It should be 
anyway, but I'll make sure.

Rich, per the guy doing the actual work the issue with Ceph was that it 
flat out would not work if some /etc/*-release file (I took poor notes) 
didn't have the string "Red Hat" in it.  Since we're stuck with OEL... 
I didn't read the Oracle docs link because I'm not doing the work, but I 
did send it on.

Bhaskar, the use case is mostly check-box compliance, so yeah, it's a 
bunch of archive files that'd we'd have to `zgrep` or something.  Or 
feed back into a one-off historical indexer instance...

Dustin, thanks for all the gotchas, about 70% of them were new to me and 
haven't come up in any of our discussions.  The expansion stuff has come 
up a lot, so it was good to get external conformation that we had it 
right.  And yes, that's painful, that's one way I was able to sell 
looking into LizardFS.

Losing a Gluster storage node and then recovering it was one of my big 
questions because it sounded quite painful.  Not sure we'll ever answer 
that if LizardFS works out.

So, many thanks again!
JP
