...h identical hardware, identical kickstart/image, inside the same blade chassis. Any idea what to test. -- Dan Hyatt Division of Statistical Genomics Washington University School of Medicine 4444 Forest Park Blvd, Campus Box 8506 St. Louis, MO 63108 314 747 4767 (o) 314 473 8713 (c) dhyatt at dsgmail.wustl.edu

I have googled, read the man page, and such. What I am trying to do is install applications to a NFS mounted drive, where the libraries and everything are locally installed on that filesystem so that it is portable across servers (I have over 100 servers which each need specific applications installed via yum and we do not want to install 100 copies). We tried the yum relocate and it was not

Hi, I am running centos6-5 on dell620 blades. mirrored local root drives several (including home) mounted filesystems. The other blades are working fine. Top indicates the server is running 1% cpu, and very little memory (idleing) There is no error in the messages file There is no amber lights on the server. When I log into my server it is fine, on my remote mounted home directory. When I cd to

I am a bit baffled on this. We recently rebuilt all our servers to CentOS release 6.8 (Final) from a prior 6.x centos release. We ran into a couple of problems such as Java not working (just had to yum install java). It was installed, but unable to create a java machine, until I yum install java solved the problem. But now a user (the big boss) is receiving xrdp errors. And it appears

Hi, I have a vector Y1 <-c(8, 11, 7, 5, 6, 3, 6, 3, 3) and an index iy <-c(c(1, 2),c(1 2), c(1, 2, 3, 4), c(2, 3, 5), c(4), c(5, 6, 7), c(7, 8, 9)) how can I produce the mean, or the sum of the elements specified in the index iy from the vector Y1? expecting something like this for the sum: Y2 19 19 31 24 5 15 12 I thought lapply function may perform this, but does not work:

When I put export DISPLAY="IP address:0.0" ip address being my windows8 desktop then xhost + I get xhost: unable to open display "IP:0.0" when I try export DISPLAY=":0.0" I get the same thing. I have centos6.4 running on a late model Dell Blade Windows8 Alienware laptop I checked the xwin firewall setting and it is set to public network access (but strangely

I have an intermittent problem with my Dell blades, out of 80 blades 69 of them kickstarted Centos 6 fine using PXE The other 11, I get a c0t0 not found error (indicating it is not finding the local disk on the blade). I can remote mount the iso image and do a basic install of centos on these blades, but when I go to do a pxe boot it gives me that error again. I have googled the issue and

Hi, I have an interesting problem. I want to be able to verify that my hostname, ipaddress, and mac address are correct in the DNS/DHCP. I have the values, how do I compare. I am able to use NSLOOKUP for the hostname=ip confirmation How do I do the ip addresss = mac address comparison I tried arp and a few other things. Almost everything on google says either to logon to DHCP (which I do

I am looking for opinions and personal experience on CentOS7 for both grid and virtualized web environments. I am currently on CentOS6.5 in a production environment. I am about to add about 50 more servers to my grid and am trying to identify the advantages and disadvantages of going to CentOS7. The good part is, that I have some tolerance for backing out and installing CentOS6.5 if 7 does not

Hi, I am still trying to get kick-start centos in my vmware5 because pxe cannot find the pxe server. I do not control the dhcp or pxe server. I have both my kickstart file and my iso image for centos6.5 on my vmware datastore, but am trying to run my kickstart file from VMware guest. Can I tell the command line to run from the datastore in VMWare? Or must I convert my kickstart file to a

Hi, I was wondering if there is a way to figure out why in SAS random beta coefficients are 0 vs. in R the beta-s are non zero. The variables of the data are nidl, time, and sub (for subject). Time and nidl are continuous variables. I am applying random coefficients model. Any input is greatly appreciated, Thanks, Aldi 1. mixed model in SAS: ====================== ods output SolutionR =

This should be simple, but it's not, unless I'm forgetting something. Writing a script, an arg is a filename. So fname=$1 But I want that expanded to include the full path and filename, not just what is given as the arg on the command line. E.g., if the user's cwd is /home/joe/a/b/c/ and he specifies ../x/file-a.ext then the function/utility should transform that into the

My environment is "heterogeneous" my authentication and home server are currently stuck on a 1G shared network, the production servers and storage servers are on a bonded 40G network, all are in the same VLAN. I have about 100 servers on the 40GB bonded network each with 12cores and 128GB of memory. They are running centos 6.6 Except for my storage servers they are all just running

I don't know if this is of interest as an alternative. I did find a cool functionality called locate and updatedb Updatedb creates the database of your files, locate does superfast searches. It essentially does a superfast "find" on your root filesystem, giving you the fully qualified path of all hits. You can create db's on your other filessytems. The problem is that it can

I might be in left field but... in init.d create a script that simply echo_ip script contents #!/bin/bash ip -4 addr |grep inet |tee /var/log/ip # this will only print the ip lines and copy to /var/log/ip ( I prefer tee over echo, for a variety of reasons) then create S99echo_ip in rc3.d so that it runs last then On 12/8/2014 5:35 PM, Florin Andrei wrote: > CentOS 7 > > How

I am trying to load centos on a gen opteron x86 but since the boxes are out of support, I am unable to find firmware for it. Any suggestions on where I might find the drivers? Thanks, Dan

About 15% of my blades wont kickstart. I checked to see, and they all seem to be 100% compatible. I currently do not own/direct access the kickstart server, I will build one later. Is it possible they fat fingered the MAC address of the problem blades when they put them into the PXE server? As I can build them from a locally mounted virtual CD, but cannot build from PXE At first I was

I need to virtualize a server, but this needs to be stable enough for production. What are the advantages/disadvantages of the different hypervisers with CENTOS ESXi (vmware) XEN KVM Primarily I will be running Centos6.4 there may or may not be a windows server. I need stability as this will be production. I will not need the equivalent of V Motion, but would like to be able to do a
