similar to: Virtualization of a production environment

I have a large set of Dell 620 blades fully populated with memory and duel socket CPUs, Centos6.4 image. I have a kickstart that I am using to pxe boot 36 blades. I have two internal drives which are raid1 (two disks formed into one, no redundancy), not san attached In the first set, 9 successfully completed. 7 more built correctly after trying another pxe boot. 2 just wont pxeboot In the

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

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 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 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

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

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

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 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

Hello Rich, Well, that stinks. I really appreciate the quick responses. Thank you for your time and effort, too. I will see what I can do to solve this problem some other way. Maybe I can virtualize my disk image maker. Thanks, Mark Thanks, Mark Husted 770-236-1242 -----Original Message----- From: Richard W.M.

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

I have a new ESXi server (5.x), and trying to load some VM guests on there. I have the guests configured, but when I try and boot from ISO image, the graphics are so bad it is futile. No worries I normally use kickstart anyways. Because the ESXi (on the same network as my physical servers) cannot talk to the PXE server. But works fine on the network (I can ssh/scp in and out of the ESXi

Title says it all - for the time being I am stuck deploying Asterisk in ESXi . We are also looking at Proxmox for our next round of servers.. Everything works fine except conference calls - very stuttery , have tried a few different codecs. I assume this is a granular clocking issue , and wondering if anyone has anything I could try to fix or mitigate the problem in ESXi environment . We have

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

Hey folks, We've got some new hardware and are trying to figure out what best to do with it. Either run CentOS right on the bare metal, or virtualize, or several combination options. Mainly looking at : - CentOS on bare metal - CentOS on ESXi 4.0 with local disk - CentOS on ESXi with 1 VM running Openfiler to serve disk to other VMs And want to benchmark these 3 scenarios So far all we

Nice to read this. Any particular reason to *not* run the OS image in glusterfs cluster?

I might be needing to utilize one of the provided virtualization packages either in a headless console only setup of CentOS or on my desktop. I havent used anything but ESXi in ages except virtualbox which I did not like at all. Most of the guests which I will need to run will be wnidows based and last I looked at this a few years ago, windows guests ran pathetic. What are some more current
