The board received this recently, and we're forwarding it for your information. MUUG makes no assertion or comment on this project whatsoever... maybe someone would like to evaluate it and do a short presentation about it? -Adam -------- Forwarded Message -------- Subject: [Board] Rockstor: A Linux and BTRFS based NAS solution Date: Sun, 26 Oct 2014 07:13:45 -0700 From: Suman Chakravartula <suman(a)rockstor.com> To: volunteers(a)lists.svlug.org, bellevuelinux(a)gmail.com, linux(a)oclug.on.ca, linux(a)lists.oregonstate.edu, lalugs(a)yahoogroups.com, oclug-owner(a)oclug.org, brian(a)zimage.com, sfvlug(a)sfvlug.org, svglug(a)svglug.net, sblug-announce(a)lists.sblug.com, officers(a)linux.ucla.edu, vclug(a)lists.actusa.net, webmaster(a)lalugs.org, officers(a)lists.svlug.org, general(a)brlug.net, joey(a)joeykelly.net, officers(a)blu.org, gaf(a)blu.org, lkvam(a)venix.com, dlslug-announce(a)borlaug.bfccomputing.com, gnhlug-announce(a)mail.gnhlugNoSpam.org, nylug-announce(a)nylug.org, cowlug(a)cowlug.org, info(a)nanlug.org, vanlug(a)robomod.net, pres(a)vlug.org, vp(a)vlug.org, secretary(a)vlug.org, treasurer(a)vlug.org, program(a)muug.mb.ca, sig(a)muug.mb.ca, monctonlug-general(a)lists.sourceforge.net, nslug(a)nslug.ns.ca, barrielug(a)bluglists.barrielug.org, group(a)bglug.ca, ottawa-gosling(a)list.goslingcommunity.org, announce(a)gtalug.org, dmitton(a)klug.on.ca, kwlug-announce(a)kwlug.org, oclug-announce(a)lists.oclug.on.ca, westtlug(a)yahoogroups.ca Hi, I'd like to introduce a project/product of mine called Rockstor. It is a Linux and BTRFS based open source NAS solution that runs on commodity hardware and provides enterprise level features with easy to use management interface and much more. Rockstor is suited for advanced home users/offices and businesses with Storage needs looking for enterprise class open source alternatives. I hope members of your LUG find Rockstor interesting and useful. Please spread the word. I'd love to have other Linux fans like me join Rockstor community, benefit from it's value and help make it better. For a live demo, download, blog and more information about Rockstor, please go to: http://rockstor.com Please contact me if you have any questions.

weird ssd image issue
by Trevor Cordes 31 Oct '14

31 Oct '14

I made a drive image of an SSD using dd a while back. I had to go back to the image to do a repair, and something is wrong with the image. When put back on the SSD and a boot is attempted, Windows7 won't boot. I check it with linux and it says the main NTFS FS is corrupted. I run fixes on it and I can mount it and look at many files, but every 50 or so files generates an I/O error when listing the directory entry, let alone trying to read the file. I do these types of images all the time and consider myself an expert at it, and never have these types of problems (even on source disks that are already dying). One of the only things I could come up with is I noticed while doing this image restore that the customer (who built it themselves) had used a SATA2 cable on a 6Gb/s SATA3 port (and the SSD is 6Gb/s). Could this have caused corruption of data "on the wire"? Is that even possible? Would wire-caused errors be detected by the mobo, or is it just the drive that does checksums? Do 6G mobos and drives detect when a 3G cable is used and downshift to 3G? The system seemed to run fine for a year setup this way, so perhaps the errors are very infrequent but doing the image at full-blast reading the whole 120GB in a few mins caused this problem? The SSD died (actually, is dying) 3 weeks after the image was made, so there is also a chance the drive was just screwing up already and giving me back bad data. However, the customer had no problems with Windows during the 3 weeks until I/O started showing up in Windows. Lastly, can a mis-wiring like this kill an SSD? This is an OCZ Vertex 420 drive (a brand I don't sell, but they bought elsewhere) and we already have RMA'd the drive once, and it definitely is dead a 2nd time now. Either OCZ SSDs suck bad, or perhaps something else is going on? Perhaps a mis-wiring can cause the SSD to detect errors and request re-dos from the OS causing a multiplication of writes? Just guessing here. Most likely the OCZ just sucks rocks. I read some other people on the net having real big problems with dying OCZ SSDs.

Ubuntu -> Kubuntu
by Kevin McGregor 28 Oct '14

28 Oct '14

I just installed Ubuntu 14.04.1 LTS, and I was wondering what Kubuntu would be like on the same system. Is it as easy as apt-get install kubuntu-desktop and logging out/in (or rebooting)? Are there any gotchas to look out for? I've installed a couple of apps, specifically VMware Workstation and Google Chrome. Will they continue to work transparently? That is, I don't need to re-install them, do I?

Why not just install kubuntu?

wanted: Seagate 2TB
by Trevor Cordes 10 Oct '14

10 Oct '14

Do you own a Seagate ST2000DM001 2TB drive? That's their cheap desktop line of which they have sold zillions. For a project, I need a close match to an existing drive. If you have one of these drives that matches what I need, I would be willing to trade you your old drive for a brand new 3TB ST3000DM001 drive! You can't lose! So check if your drive (the sticker on the top) matches: PN must be 1CH164-575 date code should be very close to 13493, preferably one that starts with "13" (the year) and maybe between 1320 and 1350 (year plus week). As a bonus, if you have a way to weigh the drive, that would really help out also (though not required). If you think you have a match, email me all the numbers on the sticker, or a pic of the sticker. Only the first close drive someone offers to me will get the deal, sorry! Thanks!

Solaris fix for the bash bug
by Kevin McGregor 30 Sep '14

30 Sep '14

I'm trying to apply IDR 126546-06 to our Solaris servers. One of them (eventually) went fine. The second one I tried failed with this message: ERROR: IDR 126546-06 cannot be applied until all Interim Relief/Diagnostics are backed out. Dryrun complete. No changes were made to the system. Okay, so how do I find a list of IDRs I need to back out of? This is Oracle Solaris 10 9/10 s10s_u9wos_14a SPARC (SunOS <server> 5.10 Generic_142909-17 sun4u sparc SUNW,Sun-Fire-V490). Both servers show have been identically installed; how do I find out the differences, on a package basis? Kevin

Does anyone have an opinion ( ;-) ) on which desktop SSDs to buy or avoid in the ~250 GB size? How about the Kingston HyperX Fury 240GB SSD SATA3 SandForce SF2281 <http://www.ncix.com/detail/kingston-hyperx-fury-240gb-ssd-82-100152-1342.htm> ? (E.g. $140 + tax & shipping from NCIX) Kevin
