VNC Server Centos 7 specify window manager
by samphar 30 May '15

30 May '15

I have a simple question, how do I specify a gnome session with VNc Server. I correctly setup up the connections but when I log in all I get is a blue screen with a checkbox in the upper left corner saying "Accept clipboard from viewers". My guess is that I am loading generuc X11 by default. How do I specify in the etc/systemd/system/vncserver@:4.service file that I want it to load gnome? I tried editing my .vnc/xstartup file but that seems to have no effect. my xstartup file #!/bin/sh exec gnome-session & ~

Getting Megaraid Software Manager Installed On CentOS 7
by Kirk Bocek 29 May '15

29 May '15

Well I'm pleased that my raid card post brought all the enthusiasts out of the woodwork. So who has installed LSI's MSM software under CentOS 7? I've downloaded the linux-x64 package from: http://www.lsi.com/products/raid-controllers/pages/megaraid-sas-9361-8i.aspx Extracted the files and run "install.csh -a". This installs vivaldiframeworkd under /etc/rc.d/init.d and that runs fine. I can access the host from a Windows install of MSM just fine. What seems to missing is the monitoring software. I think the run-time script is called mr_monitor. It doesn't seem to be installed. Attempts to configure monitor alerts from Windows returns "monitor is unreachable." Does anyone have any idea what is going on?

Booting back into CentOS-6
by Timothy Murphy 29 May '15

29 May '15

I'm currently running CentOS-7, but I'd like to re-boot into CentOS-6.5 which I have on another partition. Although this OS is in the grub list when I boot, if I try to run it I get a segfault. I guess this is something to do with the change from grub to grub2? In any case, I'm wondering if there is any simple way of booting into both CentOS-6 and CentOS-7? -- Timothy Murphy gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin

This, IMHO, is one of the more annoying bugs with the newer GRUB (which i assume is the bootloader you are using). Specifically the newer grub can't, won't boot from a drive other than the one grub is on. suggest you revert to grub 0.97 or, if any boot loader is or can be put on the drive with the 6.5 distro you can make that drive the boot drive in the bios, which is how i do it. i.e. i just put grub on any drive i might want to boot from and install etc. with the drive i want to be able to boot to set as the boot drive in the bios. of course, depending on how you are mounting drives this may break links etc. since the bios will have different names for the drives due to the different order of the boot media list in the bios. hope that helps, it is highly annoying.

New controller card issues
by m.roth＠5-cent.us 29 May '15

29 May '15

Running CentOS 5 (long story, will be updated some day). A 5 yr old Dell PE R415. Whoever spec'd the order, they got the cheapest, embedded controller. Push came to shove - these things gag on a drive > 2TB. So, we bought some PERC H200's for it, and its two mates. This morning, I brought the system down, and put in the card, and moved the SATA cables. This did not end well. The new card seemed to see the drives, it loaded the initrd... and kernel panic'd every time when it went to switch root. I went into the card's firmware and set the first drive to boot. No change. Upshot was that I actually had to pull the card - once it was in, and set, it insisted that it was 0 in boot order, and would not let me take it out, even though I'd reconnected the SATA connector to the on-board one. So: my manager and I are suspecting that the initrd simply doesn't have the driver for the card. I'm going to rebuild the initrd (once I figure out how to do that without the card in the box). The reason I'm posting is to ask y'all if anyone out there has some *other* thoughts as to what the problem might be, other than the initrd. Thanks in advance. mark
