Finding the correct ext3-fs dm/LVM?
by Kai Schaetzl 20 Oct '08

20 Oct '08

I'm getting ext3-fs maximal mount count warnings on logical volumes that are regularly mounted und unmounted for backup. Of course, I can just tune2fs all of them to stop that. But, if I wanted to find out for instance which one "dm-16" is, how do I do that? Kai -- Kai Schätzl, Berlin, Germany Get your web at Conactive Internet Services: http://www.conactive.com

Only the client gets installed. The argument was that their support folks were spending an inordinate amount of time helping people get their databases configured and running.

Centos 5 and Driver Disks
by Clint Dilks 19 Oct '08

19 Oct '08

Hi, I am trying to install CentOS 5.2 on a Dell PowerEdge R905, and a problem that you run into is that the DVD Drive on the system is not recognized by the kernel. I have done some searching on the web and found http://kbase.redhat.com/faq/FAQ_103_13121.shtm and obtained the driver disk that it mentions. Having followed the instructions I can see and select the driver disk image but the install thinks there are no appropriate drivers in the image. Can someone please confirm or deny that I should be able to use a Red Hat Enterprise Linux 5 Driver with CentOS 5 without issue ? It isn't a big deal as I will try a Network based install or use a USB DVD drive but I just want to confirm if using a RHEL 5 Driver Disk should work :) Thanks, and have a nice day

Problems with Thunderbird
by ArcosCom Linux User 19 Oct '08

19 Oct '08

On new CentOS 5.2 installation (and ugradation before config the diferent programs I use), I'm having problems with Thunderbird 2.0.0.17. Problem 1: I configured my e-mail account (as I have in my old machine) and I have no access to my pop3 and/or smtp servers. I write my user for the access, but thunderbird no ask my password anytime. Problem 2: I installed lightning, but I can't add any new calendar to it (local or remote). Does anyone have these problems or knows how to solve them? Regards

new list proposal
by Karanbir Singh 18 Oct '08

18 Oct '08

One thing that we are often blamed for is trying to stifle conversations and to discourage people from commenting / contributing / encouraging conversations. And that cant be further from the truth, really. We are all pro-community ( and when I say we, I mean everyone - including the contributors, developers, admins, users, abusers and hey upstream too ). However, one thing that does get in the way, often, and something that we all feel creates a higher 'noise' ratio is conversations on this list about semi-related stuff, but not something that directly contributes to the general users of CentOS. Conversations that specifically address four areas: - technologies - best practices - deployment strategies and tools - management strategies and tools And to better cater to these conversations, as well as further encourage such content, we'd like to propose creating a 'centos-tech' list. Over a period of time, we would like to see the CentOS list become a more user help and distro specific list, with generic conversations moving to the centos-tech list. -- Karanbir Singh : http://www.karan.org/ : 2522219@icq
