I've been messing around with "glusterfs" and it's pretty cool. I build 3 machine running RHEL7.2 each with an extra 250GB disk. I then setup a filesystem that stripes across all three machines. So it looks like a single 750GB filesystem. Over gigE I'm seeing okay performance ~50MB/s. Cool stuff. Next on my list of filesystems to play with it Lustre.

Nathan’s solution worked, thanks to all for the replies. I do feel better this was not a solution that could fit into a tweet. Theo’s is elegant, but there are spaces in the data, and John’s would have work, but I can’t use perl in the environment I’m working in. Mike awk -F, '{linecount[$3]++;tmp=dup[$3];if(length(tmp)==0){dup[$3]=$0}else{dup[$3]=dup[$3]"\n"$0}} END {for (count in linecount){if(linecount[count]>1){print dup[count]}}}' Hopefully this is not a homework problem.

(for meeting projectors) laptops,VGA-out,linux....

by Doug Mildram

doug> Thanks Tim for bringing a functional laptop w/linux for last night's meeting. Our VGA-out projector worked fine as he installed a linux Mint VM (Mate Cinnamon) onto it. When that finished, I wanted to show/compare Mint Mate, which I had already on my laptop. When I unplugged Tim's laptop from VGA-out and tried my own thinkpad running Mint Mate (dualbooted, my alternate OS).....well,.....chirp. The projector stopped projecting. My Fn-F7 key seemed to be trying to cycle thru the blind toggles/choices (Duplicate display? screen-only? VGA-only might expect), but no video came out, I had to give up, not having tried VGA-out ever while running linux on my laptop. We put Tim's back onto VGA-out, and it also seemed dead, but we chose not to fight it, meeting being close enough to stop caring about projector, and it "wasnt a proud moment" for me. SO I WENT HOME and plugged my (same) laptop into my TV's VGA-in port. Started by booting win7. I'd never noticed a detail : at WHICH POINT does this start working....should I expect to see the dualboot/GRUB menu on TV? Apparently not. Soon enough though, Win7 (the OS preinstalled by Lenovo/thinkpad) came up and VGA-out/TV started working as usual. (somewhere AFTER "Resuming Windows", it starts working). To control VGA-out, Fn-F7 works ...I've got (4) choices: Duplicate, Extend(laptop-screen=#1, TV-VGAout=screen2), Projector Only (turns off laptop display), and Disconnect Projector (only laptop display ON). No doubt (i surmise), thanks to windows drivers. Feels like I learned: OS controls VGA-out (somehow naively I was inclined to believe this was more of an OS-independent hardware function). OK, now rebooted laptop/win7 to try Linux Mint from a win7 state with "Duplicate" working. "Shutting down Windows" displayed....laptop goes thru boot/BIOS?...TV is blank now, I've learned to expect this....Linux kernel boots, and I see some of the minimal console text messages as usual ALSO ON TV, laptop-screen AND TV quickly go to graphical mode, also displaying the Mate background... and this is where I was the most surprised. TV/VGA-out appeared "frozen' with the Mate background, appearing much like my laptop screen BUT MINUS anything else (no bottom launch/status/"panel" bar. Whatever I launch on my laptop screen, does not appear on VGA-out. Fascinating! Wed eve late, at my house, I could swear Fn-F7 still wasnt doing anything. But this Thurs AM, it DOES start working a bit (same 4 choices, but blind, and it's strange. TV/VGA-out doesnt show EVERYTHING). I wonder if I'd rebooted at the meeting, would that have helped, probably. Today I play with it some more (ALT-F2 helps when I'm in that semi-blind VGA-out situation, getting SOME things to show on TV) even though I'm not likely to use this feature much?ever? at home, unless I break a leg. Caveat, practice what you bring for meetings to project-OUT! HDMI is also an option in our WPI meeting/conf rms if you have it. ---trivia for Mate interest... (Mate = lightweight alternate to Cinnamon. Their start/launch menus are different, and I can find good stuff in Mate's Control Center.
