Hi all. I have a CentOS server: CentOS release 5.7 (Final) 2.6.18-274.3.1.el5 x86_64 I have two SSD disks attached: smartctl -i /dev/sdc smartctl version 5.38 [x86_64-redhat-linux-gnu] Copyright (C) 2002-8 Bruce Allen Home page is http://smartmontools.sourceforge.net/ === START OF INFORMATION SECTION === Device Model: INTEL SSDSA2CW120G3 Serial Number: CVPR13010957120LGN Firmware

in large raids, I label my disks with the last 4 or 6 digits of the drive serial number (or for SAS disks, the WWN). this is visible via smartctl, and I record it with the zpool documentation I keep on each server (typically a text file on a cloud drive). zpools don't actually care WHAT slot a given pool member is in, you can shut the box down, shuffle all the disks, boot back up and

I don't believe that is correct. LSI acquired 3ware, and Avago acquired LSI.

I use RODBC and RpgSQL quite a lot to access files stored in another machine under PostgreSQL. Since I am now using files which do not fit into R's memory, I would like to take random samples. What I would like is to issue a query such as SELECT * FROM file WHERE runif > 0.9 with "runif" being a uniformly distributed random number, generated on the fly; but I cannot

Greetings. Here is sample code, with some comments. It shows how I can simulate data and estimate glm with binomial family when there is no individual level random error, but when I add random error into the linear predictor, I have a difficult time getting reasonable estimates of the model parameters or the variance component. There are no clusters here, just individual level responses, so

LSI/Avago?s web pages don?t have any downloads for the SAS2308, so I think I?m out of luck wrt MegaRAID. Bounced the node, confirmed MPT Firmware 15.10.09.00-IT. HP Driver is v 15.10.04.00. Both are the latest from HP. Unsure why, but the module itself reports version 20.100.00.00: [root at r1k1 sys] # cat module/mpt2sas/version 20.100.00.00 On 2016-05-25, 3:20 PM, "centos-bounces at

I've got a 1Tb USB disc that appears to be dying - eg it took about 10 days (!) to run 'badblocks -nsv /dev/sdc' and it only did less than 2% in that time. Read access became _really_ slow. So there's definitely something amiss and I've got it offline. There's no drama about the content as I have other backups and I'm resigned to junking the thing, but I'm curious

hi Up for grabs, a few packs of CentOS stickers ( but only to the EU ) These already have Royal Mail EU stamps, so I cant send them elsewhere. There are 20 packs in all, each pack has 4 x 1" by 1" CentOS logo sticker 4 x 2.5" by 2.5" CentOS logo sticker 2 x 2" round CentOS sticker Want one ? email me at kbsingh at centos.org and give me your address, I'll aim to

I've seen similar cases where a USB drive appears to fail but the SMART reports success. The most recent was a 500 GB disk which had internally a Seagate Barracuda SATA drive. It appeared to work well until I sent it a largish (7GB) tarball. As well as SMART I ran a surface check and exercise, all passed. The tar kept failing. I can't test further, the disk has been broken up for
