similar to: SATA disk issue

I'm in the process of upgrading the hardware in a small cluster based on CentOS 5 and Xen. The old hardware had dual ide disks, the new dual SATA. In both cases /boot and / are on RAID 1 partitions on each of the disks. The remainder of the disk is a RAID 0 with volume group laid on top. Here's my problem, when booting to Xen the box gets to the point of mounting filesystems for dom0,

Following up to myself here, I tracked the problem in my original posting down to a memory issue with the system board, found that I had to manually specify the amount of memory using the mem= parameter at boot time. Since then Asus has released an updated bios that has everything working fine without the parameter. Now there is a new issue that again appears to be related to the disks. When

I've got an odd situation that I need some advise on. I have two computers that I am planning to use as a cluster. I initially started with some left over Compaq Presairos with 667MHz CPUs. I loaded CentOS 4.3 and later updated to 4.4. Things ran normally, albeit slowly. I had an opportunity to upgrade to a pair of IBM Netvistas with 2.26 GHz CPUs, I did this by transferring the

Hi, I'm probably being fairly stupid. But I did the following, starting with the following two files: # tcprobe -i vts_01.m2v [tcprobe] MPEG elementary stream (ES) [tcprobe] summary for vts_01.m2v, (*) = not default, 0 = not detected import frame size: -g 720x576 [720x576] aspect ratio: 16:9 (*) frame rate: -f 25.000 [25.000] frc=3 # tcprobe -i vts_01.m2a

I have configured 2x 500G sata HDD as Software RAID1 with three partitions md0,md1 and md2 with md2 as 400+ gigs Now it is almost 36 hours the status is cat /proc/mdstat Personalities : [raid1] md0 : active raid1 hdb1[1] hda1[0] 104320 blocks [2/2] [UU] resync=DELAYED md1 : active raid1 hdb2[1] hda2[0] 4096448 blocks [2/2] [UU] resync=DELAYED md2 : active raid1

Sorry I had typo in previous email, this typo corrected version: Dear R experts I have simple question, please execuse me: #example data, the real data consists of 20000 pairs of variables K1 <- c(1,2,1, 1, 1,1); K2 <- c(1, 1,2,2, 1,2); K3 <- c(3, 1, 3, 3, 1, 3) M1a <- rep( K1, 100); M1b <- rep(K2, 100) M2a <- rep(K1, 100); M2b <- rep(K1, 100) M3a <- rep(K1, 100); M3b

Dear R users, I have now tried out several options of obtaining p-values for (quasi)poisson lmer models, including Markov-chain Monte Carlo sampling and single-term deletions with subsequent chi-square tests (although I am aware that the latter may be problematic). However, I encountered several problems that can be classified as (1) the quasipoisson lmer model does not give p-values when

Hello, I have two disks sda and sdb. One of the was broken so I have changed the broken disk with a working one. I started the server in rescue mode, and created the partional table, and added all the partitions to the software raid. *I have added the partitions to the RAID, and reboot.* # mdadm /dev/md0 --add /dev/sdb1 # mdadm /dev/md1 --add /dev/sdb2 # mdadm /dev/md2 --add /dev/sdb3 # mdadm

Dear R experts. I might be missing something obvious. I have been trying to fix this problem for some weeks. Please help. #data ped <- c(rep(1, 4), rep(2, 3), rep(3, 3)) y <- rnorm(10, 8, 2) # variable set 1 M1a <- sample (c(1, 2,3), 10, replace= T) M1b <- sample (c(1, 2,3), 10, replace= T) M1aP1 <- sample (c(1, 2,3), 10, replace= T) M1bP2 <- sample (c(1, 2,3), 10, replace= T)

I have a long string. i want to sepearate a 10 digit phone no from it. eg "my no is 9876543210 is personal no and my official no is 123-456-8907. you can use any of these" i want to seperate the 9876543210 and 123-456-8907 from this. therev may be many phone nos in the string. how to do it ----- Thanks in Advance Arun -- View this message in context:

Hello Since I got the IBM Netvista to boot Linux, and am still waiting for the Compact Flash cards that I ordered, I was wondering if someone knew of an Asterisk distribution that can run on that kind of diskless host? I've taken a look at AstLinux and AskoziaPBX, but they both seem to be meant to be installed on a solid-state medium instead of RAM. For instance, the Netvista is unable to

Hi. CENTOS 7.6.1810, fresh install - use this as a base to create/upgrade new/old machines. I was trying to setup two disks as a RAID1 array, using these lines mdadm --create --verbose /dev/md0 --level=0 --raid-devices=2 /dev/sdb1 /dev/sdc1 mdadm --create --verbose /dev/md1 --level=0 --raid-devices=2 /dev/sdb2 /dev/sdc2 mdadm --create --verbose /dev/md2 --level=0 --raid-devices=2

Hi all, I have two time series that I would like to correlate but as they are autocorrelated, I am "pre-whitening" them first by fitting ARIMA models, then correlating their residuals....as described in https://onlinecourses.science.psu.edu/stat510/?q=node/75 However, http://www.stat.pitt.edu/stoffer/tsa2/Rissues.htm discusses some issues with ARIMA in R. In particular, for issue 2, if

So I'm trying to RAID-1 this system which has two identical disks installed in it, and it isn't working for some reason. I started by doing a CentOS-4 install on /dev/sda1 as root, and with /dev/sda2 as my swap. I finish the install, yum update, and then I want to make the mirrors. I copy the partition table from one disk to the other: # sfdisk -d /dev/sda | sfdisk /dev/sdb I create

Hi,we have Centos 5.4 server and according to me we have strange problem.

I am stuck on a simple problem where an example works fine but the real one does not. I have a data.frame where I wish to sum up some values across the rows and create a new data.frame with some of old data.frame variables and the new summed variable. It works fine in my simple example but I am doing something wrong in the real world. In the real world I am loading a labeled data.frame. The
