similar to: question about disk performance in domU

Hi all, When I ran the experiments to compare an application''s execution time in both a domU (named cctest1) and a native Linux machine (named ccn10), I noticed the application executes faster in domU. The host of the domU (named ccn9) and ccn10 are two nodes of a cluster and they have same hardware configurations. domU (cctest1) is created by exporting loopback files from dom0 on

I've tried several times to resize one of my ocfs volumes[see emcpowere1 below] I'm on the latest [prod] version of ocfs/ocfs-tools as of 3pm EST on 18JUL04. Per instructions... Take down db, unmount all ocfs drives, use ' tuneocfs -F -S 100G /dev/emcpowere1 ' Supposedly this should work, but I get get.... The size specified, 100G, is larger than the device size, 59G. Aborting.

Hello, I'm plotting two sets of data referenced to either the left or right y-axes. The first, water table depth (blue circles), is plotted on the left y-axis in reverse order (0 at the top) as this is more intuitive when thinking in terms of depth. The second is electrical conductance (a surrogate for salinity), and is referenced to the right y-axis. The data and plot commands follow

Hello, I was unable to find clues to my problem in ?optim. Using the data and code below, I get an error ("system is exactly singular") when a particular line of code is left in, but have found that 'optim' works when I comment it out. The line of code in question is after the closeAllConnections() line of code and contains a call to "na.approx" from the zoo package.

Hi, I have two 320 GB SATA disks (/dev/sda, /dev/sdb) in a server running CentOS release 5. They both have three partitions setup as RAID1 using md (boot, swap, and an LVM data partition). # cat /proc/mdstat Personalities : [raid1] md0 : active raid1 sdb1[1] sda1[0] 104320 blocks [2/2] [UU] md1 : active raid1 sdb2[1] sda2[0] 4192896 blocks [2/2] [UU] md2 : active raid1 sdb3[1]

Hi, I'm getting horrible performance on my samba server, and I am unsure of the cause after reading, benchmarking, and tuning. My server is a K6-500 with 43MB of RAM, standard x86 hardware. The OS is Slackware 10.0 w/ 2.6.7 kernel I've had similar problems with the 2.4.26 kernel. I use samba version 3.0.5. I've listed my partitions below, as well as the drive models. I have a

Dear list members, I am new member and fairly new into R world! I hope what I have is not beyond the purpose of this list. I did first search for similar experimental designs without success. I want to perform an ANOVA analysis using the aov() function. I am not 100% sure that I have it right. If anyone can help me, that will be greatly appreciated. My design is not balanced for any of the

Hi, Running a bunch of CentOS servers on 2U supermicro equipment, usually with 8 drives on Adaptec SmartRAID V or LSI Megaraid. In designing a rack in a data center, the question arises as to how to measure the amperage the server uses, prior to investing in power drops that actually do that for you, even remotely, for about $260.00-300USD per unit. This number is the important one these days

Hello I am reshaping a data.frame bids --> reshaped as shown below. I thought this should be possible with a single invocation of reshape, but the only way I came up with is reshaping subsets for each keyword and then joining them together. Does anyone have an idea how to solve this in a more elegant way? Efficiency is a concern as the datasets are very large. Is there a way to specify

After snapshot-delete, the qcow2 image file size doesn't decrease, isn't that a waste of disk space? Would someone please tell me how to decrease the file size when snapshot-delete, if that's possible? The image file name of my virtual machine is d0.qcow As follows: [root at test1 ]# virsh list Id Name State

Dear all, When I debugged the execution performance of an application using strace, I found there are some system calls like open and stat64 which run faster on XenLinux than the standard Linux. The following is the output of running "strace -c /bin/sh -c /bin/echo foo" on both systems. An open call runs averagely 109 usec on standard Linux but only 41 usecs on XenLinux. An stat64

Hello, running 0.99.10.6 (but seen it before that, too). Also (quite obviously) running 5 auth processes, given the fact that this is a pretty busy box and I didn't want to introduce any artificial bottlenecks. Alas with them eating up half of the free memory (which would go to a much better use as FS cache) I'm getting sorta concerned. If it's not a leak, it's caching something

I am trying to install a CentOS 6.4 x86_64 VM using a CentOS 5.9 x86_64 host, but its install has froze *twice*. What I am doing is to create a 10gig LVM volume, which I put a MS-DOS partition table on (using fdisk). I then format the only partition to ext3, install grub and install the pxeboot kernel and initrd.img and a simple grub.conf to load this. I have the CentOS 6.4 x86_64 ISOs mounted

Hello everyone, I have released SYSLINUX 2.01. It's almost identical to 2.01-pre5, but I figured it was time to get it out the door, especially since I won't have time to work on it for the next few weeks. Changes in 2.01: * MEMDISK: Fix memory sizing bug when the ramdisk crosses the 16 MB boundary. * MEMDISK: Add a "pause" option to stop

I am just starting to learn Sweave (really neat tool). I am pretty early in the learning curve (I had to think a moment ago whether a # or % was the appropriate comment character). I have successfully incorporated simple graphics and outputs, but am having trouble getting a latex (xtable) table to function properly. Latex is seemingly treating the xtable code as input or verbatim text. That
