similar to: Problem with blades that wont kickstart

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 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

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

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 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

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

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

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

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

Hi there. I got myself a pair of old Intel Xeon blades, which I plan to repurpose with CentOS. The model is : HP bl20p-g3 server blade Manual http://h18004.www1.hp.com/products/quickspecs/12322_ca/12322_ca.pdf Now, the main problem with this hardware is that LVD UW SCSI HDDs are hard to find and hella expensive if you find em (and of reduced capacity). Any of you know: 1. If there's any

Any suggestions for a good lightweight pdf reader for my centos servers? Thanks, -- Dan Hyatt

Hi all, A few months ago, I migrated some of our internal servers to HP blades, as the VMWare box they were previously running on was getting too slow. However, it wasn't without it's problems, and eventually the only way I could get them to work was: Install the same version of CentOS on the blade (believed to be 5.0, but /etc/redhat-release says 5.2) Took down both servers, booting

Greetings, We have purchased an IBM BladeCenter and I am in the process of testing Linux installation on these things (boot off SAN i.e. qla2300 driver, not using internal drives). My distro of choice is Debian, however, since I'm really not interested in trying to hand compile all the drivers, I decided to try CentOS (which I'm so far very impressed with). On boot, as with 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
