CentOS 6 - Preferable snapshots via LVM, EXT4 or XFS
by aurfalien 30 Aug '12

30 Aug '12

Hi all, I read some where that due to UUID conflicts, EXT4 + LVM snapshots is still the way to go in Cent 6. I do love XFS but was wondering your thoughts and experiences. - aurf

bash job control and signals
by Theo Band 30 Aug '12

30 Aug '12

I want to suspend a script using a signal but that does not work as I want. I made an example script: $ cat script #!/bin/bash echo $$ gkrellm If run this script gkrellm starts up and I can use job control from the terminal to suspend the script (CTRL-Z) and resume it (fg or bg). If I suspend I can see that gkrellm freezes (that's why I choose gkrellm in this example): $ ./script 23632 --CTRL-Z-- [3]+ Stopped ./script $ fg ./script Next I want to do exactly the same but from another terminal using a signal: kill -SIGSTOP 23632 [3]+ Stopped ./script So the bash script is indeed suspended, but the gkrellm keeps running. I can of course signal SIGSTOP to gkrellm and then this gkrellm will suspend as well. I have however an application that suspends my script and I cannot change this application. I want all processes that are children also to become suspended. I tried to add a trap, but that did not work. Any idea how to make this work? Theo

The kvm guests get the user applications. I simply want to have a similar arrangement on my personal workstation so that my experiments do not become invisibly dependent upon something I have installed for my own use. Basically, I want to simply leave the host configuration alone once kvm is running and do my mucking about in a virtual machine. -- *** E-Mail is NOT a SECURE channel *** James B.

Cut command behaviour - bug or feature
by Rajagopal Swaminathan 29 Aug '12

29 Aug '12

Greetings, I have a CSV file with three fields. eg. a1,b1,c1 a2,b2,c2 .... I wanted the output to be: b1,c1,a1 b2,c2,a2 .... the command cut -d, -f2,3,1 <file> returns a1,b1,c1 cut -d, -f2,3 <file> works as advertised. Is it specific to linux? In that case how do I go about swapping two columns? I do not think a gazzillion byte gui is required. The file size is about 43Megs. any ideas? -- Regards, Rajagopal

KVM as a desktop
by James B. Byrne 29 Aug '12

29 Aug '12

I am nearing the end of a project that moved our disparate services and hosts onto kvm virtualized servers. What I am now contemplating is setting up my desktop as a virtual host and using one of the guests as my primary workstation. However, I am not sure how this would work in practice. I am accustomed to working with virtual instances via ssh (a terminal window) and with my desktop system in a Gnome window manager. Is there a reference somewhere that outlines the mechanics of logging into a virtual guest's graphical desktop directly from the physical console of the kvm host system? -- *** E-Mail is NOT a SECURE channel *** James B.

I like to use freenx to host the desktop and the NX client to display it. That should work regardless of whether the desktop is a VM or not and regardless of the OS or location of the display - and it wouldn't surprise me if it performs better than whatever the built-in KVM mechanism uses. Even if you normally work locally, you may find it handy to be able to pick up the display from elsewhere with everything still running and have good performance. -----Original Message----- Not sure if freeNX is the best way to go. How about x2go: http://www.x2go.org/ Or thinlink from http://www.cendio.com/ Hw ______________________________________________________________________ Dit bericht kan informatie bevatten die niet voor u is bestemd.

updatedb taking too long
by Tim Dunphy 29 Aug '12

Hi list For some reason mlocate is taking a long time when I run the updatedb command. Have a look! [root@beta:~] #time updatedb real 19m48.729s user 0m0.400s sys 0m2.728s It's not a big volume by any means [root@beta:~] #df -h Filesystem Size Used Avail Use% Mounted on /dev/xvda1 75G 9.1G 63G 13% / So I'm wondering what could be causing this command to take so long. I'm running centos 5.8 in a xen vm. I was hoping I could get some advice that would help me troubleshoot this problem. Thanks!
