We have used that drive for 2 years with no issues.

Yeah, I have about 50 of them in raid cards and doing software raid. Never done that. :) No need. We have yet to have one fail in 2 years :) -----Original Message----- From: centos-bounces at centos.org [mailto:centos-bounces at centos.org] On Behalf Of Christer Solskogen Sent: Tuesday, November 10, 2015 06:17 PM To: centos at centos.org Subject: Re: [CentOS] Samsung evo 840 fixes On

Hi! I'm having trouble compiling llvm/clang when GCC-4.8.0 is installed. Even with llvm/clang installed (and used) and gcc-4.8 it always comes to this: /data/home/solskogen/obj/_build/llvm.final.x86_64-unknown-linux-gnu/Release/bin/llvm-tblgen -I /data/home/solskogen/mingw-w64-builder/trunk/bin/llvm/lib/IR -I /data/home/solskogen/mingw-w64-builder/trunk/bin/llvm/include -I

I''ve been looking into the performance impact of NCQ. Here''s what i found out: http://blogs.sun.com/erickustarz/entry/ncq_performance_analysis Curiously, there''s not too much performance data on NCQ available via a google search ... enjoy, eric

Hi folks. I'm posting this to both the Fedora as well as the CentOS lists in hopes that somewhere, someone can help me figure out what's going on. I have a dual Xeon 3GHz server that's performing rather slow when it comes to disk activities. The machine is configured with a single 160 GiB OS drive (with CentOS 5.0) and 4x500 GiB drives setup in a RAID-5 configuration.

Does CentOS support NCQ on SATA drives? If so is there something I must do to turn this support on? Matt

fun example that shows NCQ lowers wait and %w, but doesn''t have much impact on final speed. [scrubbing, devs reordered for clarity] extended device statistics device r/s w/s kr/s kw/s wait actv svc_t %w %b sd2 454.7 0.0 47168.0 0.0 0.0 5.7 12.6 0 74 sd4 440.7 0.0 45825.9 0.0 0.0 5.5 12.4 0 78 sd6 445.7 0.0

Is there anyway to enable NCQ on CentOS 4.6? I guess anouther question is on a somewhat high activity mail server with a single SATA2 drive will it do any good? Matt

I have two identical servers. The only difference is that the first one has Maxtor 250G drives and the second one has Seagate 320G drives. OS: CentOS-4.4 (fully patched) CPU: dual Opteron 280 Memory: 16GB Raid card: 3ware 9550Sx-8LP Raid volume: 4-disk Raid 5 with NCQ and Write Cache enabled On the first server I have decent performance. Nothing spectacular, but good enough. The second one

Does SATA Native Command Queueing and Linux software RAID1 play well together or is it better to turn off NCQ when doing software RAID?

All, I have a problem with a new Seagate hard disk. The problem occurs when i go to install CentOS, i insert the cd and start the boot up process, when it gets to the section where it detects the hard disks, the driver is seems crashes, the message it produces complains about no one caring about a interrupt on IRQ11. The hard disk is a Seagate 200GB 8MB SATA150 NCQ drive, on a SilliconImage

Ruby Forum Search did not work, and I did not find any postings about http://laszlo-plugin.rubyforge.org/. OpenLaszlo is a framework handling the GUI part, or the V in MVC. See http://www.laszlosystems.com/lps/laszlo-in-ten-minutes/ for info about Laszlo itself. My question is, does anybody have experience with this framework, especially combined with Rails? Or, could I get some of the best
