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

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

I'm running into some issues with regard to isolinux and memdisk, and am not sure where to ask/look in the best way possible. These are DOS-related issues. So here goes: * Can MEMDISK map a imagefile (compressed? harddisk?) to more than (and/or beyond) 4GB of memory? Say you'd have 8/16GBGB and want 4GB available to the user so might as well use the other 4/12GB for MEMDISK. Or max

I am trying to acheve pxe booting of a image of barts boot disk (www.nu2.nu). I have managed to get LTSP booting via pxelinux, so I know my dhcp/tftp servers are ok. However when I try to boot memdisk with either a stock suselinux boot image file (taken from SuSE 9.1) or my dos disk (created by dd if=/dev/fd0 of=/imagefile) I get output like MEMDISK 2.08 command line : BOOT_IMAGE=memdisk

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 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 all, I have 4 glusterd servers running a single glusterfs volume. The volume was created using the gluster command line, with no changes from default. The same machines all mount the volume using the native glusterfs client: [root at localhost ~]# gluster volume create datastore replica 2 transport tcp 192.168.253.1:/glusterfs/primary 192.168.253.3:/glusterfs/secondary

In days of old, in Solaris there was a daemon for NFS Client, and NFS server (actually several including portmap...). I am unable to find reference to the daemon that runs NFS client But the RedHat Documentation does not explain the NFS client daemon. Is this a service or something else. on centos6.5 I previously posted about a really weird root filesystem. It started on another non critical

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

Hi guys, I''m trying to do some validation on an image upload. Basically I have a model, Property, which has_many :property_images. I need to check that one image has been uploaded at least and so it was suggested I checked the number of images uploaded - @property.property_images.count > 0. Makes sense. I''ve added a validation on my Property model, like - def

Hi, I'm sorry to bring this up again but I can't quit get this too work. I'm trying to build a 2.88 floppy image so that I can use PXE to load Ghost. I'm useing the following to get a copy of the bootsector: dd if=/dev/fd0 of=bootblock bs=512 count=1 Then I build the image file with: mformat -C -t 160 -s 18 -h 2 -B bootblock x: Then use mcopy to put the required

Hi all, I've been trying out Gluster Platform, so some info will be from the management interface. If additional data from logs is required, please let me know which logfiles. When using a Gluster NFS volume as a ESXi datastore, creation of a disk file (vmdk) takes a considerable amount of time (with unfsd using 10-50% cpu) and then crashes unfsd. A reboot of the system seems necessary to

I sent a long message yesterday describing a problem I thought had to do with the JIT stubs. After further investigating, the problem seems to be in the code generation. The following basic block seems to have an error in it's code generation: __exp.exit: ; preds = %codeRepl258, %__exp_bb_bb.exit phi double [ 1.000000e+00, %codeRepl258 ], [ %.reload.reload.i,

Hi, I just resized the disk image of a virtual machine by following the recommended virt-resize procedure. The enlarged disk is working fine, and the size is correctly detected and used in the virtual machine. But "virsh vol-info /path/to/imagefile" still shows the old size and allocation. Is there a way to "fix" this, i.e. making virsh aware of the new size? Thanks. Marco

Hi there, like topic sais, I'd like to build a domain-system with two locations. Our users work one day here the other day in the other place. The two locations are connected via VPN (10MBit). To have one datastore in sync on both locations I was thinking about something like a distributed filesystem (e.g. ceph). Why? I hope to be able to setup the cluster between the two locations with a

It is now possible to build a bootable floppy image which contains HDT, with my patch applied to Erwans HDT branch: http://git.zytor.com/?p=users/erwan/hdt.git;a=commit;h=16b37fe2266c920087f88cdec94243b71218d871 Unpack the Syslinux archive and build whole Syslinux first, then cd to ./com32/hdt/ and make hdt.img $ make $ cd ./com32/hdt/ $ make hdt.img Now you have a 2.88 MB floppy image which

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
