similar to: what is device dm-2?

How does one view the dm-{n} names wrt the actual dev names? I assume it involves dmsetup but I cant figure it out. I am using iostat to track some busy disk io and don't know which dm-{n} to watch :) Thanks! jlc

All of a sudden yum hangs on a Centos 4.5 (updated to the latest patch before 4.6) when I try to use it. "clean metadata" didn't help. The output of -d5 shows it gets to the point of "Reading Local RPMDB" and then sits there. The process doesn't die, but doesn't seem to do anything from that point on. strace shows this: futex(0xb76dcae8, FUTEX_WAIT, 2, NULL I

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 Sch?tzl, Berlin, Germany Get your web at Conactive Internet Services: http://www.conactive.com

The installed php on CentOS/RHEL is the CGI version. This means I should be able to get command line arguments with $GLOBALS[''argv''] or $_SERVER[''argv'']. That''s how the php documentation tells and how it works f.i. on Suse. However, on CentOS I get them only when I use the -n switch to php (no php.ini). The problem with -n is that php cannot find

We are serving the mp3s with .nsv endings since that is what the oddcast plugin seems to send by default when mp3 is

I have a local mirror of CentOS5 base and updates. Now with 5 having become 5.1 and in case I just want to keep on updating (at the moment) is it enough that I update the mirror of updates or do I also need an update of the base repo?

Is there a program on CentOS which will sort my passwd/group etc. files by username or uid/gid? On Suse I can do this with a sysconfig switch and Suseconfig, is there something similar on RH-based systems?

The new virtual machine manager in Centos 5.1 displays some weird behavior here and I assume it's because the UUID of one running VM is the same as of a VM that is shut down. I used the same config file template for creating all my test VMs, so several have the same UUID. Didn't produce any problems with xm. But the new VM manager in Gnome shows active and inactive VMs and identifies

I took over a custom firewall script from my older Suse machines to my Dom-Us and it works just fine. Doing the same for Dom-0 immediately killed all traffic for the VMs. As there was no need before I had been dropping everything on the FORWARD chain. After ACCEPTing all for FORWARD my VMs are happy again. What's best practice on Dom-0, what do you do? Can I restrict the forwarding, in

Even a minimal install with nobase installs about 40-50 i386 packages on a 64bit-System. I know this has come up before and thought it might be an FAQ, but I can't find it on the wiki. Some questions are answered here: http://www.goitworld.com/rhelcentos-x86_64-and-i386-packages-mess/ but I have these remaining: - can I tell via kickstart to just install the 64bit packages? - is it safe to

I converted a physical maschine running CentOS 4.6 to a Xen VM on a CentOS 5 host. Almost everything was running when I decided to rsync /lib and /usr a while later in order to get updated files and get the one or two non-working programs to work. There are differences because of the xenU kernel I didn't think about. I forgot to exclude rpm database and /lib/modules. Because the synced

I'm new to streaming or music hearing over the wire, I still prefer my old-fashioned stereo equipment :-) But a friend asked me to setup a shoutcast server for him, so I went out and installed it, played a bit with it and didn't like it. So I looked for an open source alternative and found Icecast. Installed fine, works fine. But there is one thing which puzzles me and I hope someone

I figured I try if I can mirror the base and updates repos locally. There's no tutorial for that, only one about creating your own repo of packages which is not the same. So, I just mirrored all the stuff with wget and changed the baseurl in the repo files and hoped that's enough. Works. So easy you don't need a tutorial. *But* I then realized that the updates directory contains

I setup a kickstart file that contains only @core and several packages explicitely listed. postfix is listed, sendmail is not. And there's no package where I would think it needs cups. Nevertheless, after the install I now have postfix *and* sendmail on the machine and sendmail even being enabled. And cups is installed. How can I find out what forced them (and probably many other unwanted

I''m trying to get DHCP working with DomU clients. I don''t want to use libvirtd. There''s a dhcpd on the machine and it works fine for all clients in the network, but not for DomUs. If I set a static IP on the DomU all networking for them is fine, so there''s no general networking problem. I use the xen 3.2 packages for CentOS on CentOS 5.1. There was a public

I usually don't setup any GUI on my Linux systems. Yesterday I installed with X and Gnome on a spare system for some testing and hit a problem. Right after login the system freezes. The system froze already earlier when I opted to test the sound card on the Welcome screen and when I login with the alternative login choice xterm and shut down it freezes when "saving mixer

This is my first major version update after using a local repo. It seems that before I can "yum update" I have to fetch the complete new 5.2 base? Is this correct? When I run yum update it now fails with various strange dependency errors although all the updates are synced. When I change to using the original repo file it wants to download many many more and shows a lot of files that

My update to 5.2 fails on one machine because of this error: Transaction Check Error: file /etc/init.d from install of chkconfig-1.3.30.1-2 conflicts with file from package AcronisAgentLinux-9.5.8076-1 file /etc/init.d from install of chkconfig-1.3.30.1-2 conflicts with file from package TrueImageAgent-9.5.8076-1 Obviously, both packages created (completely unnecessarily) the /etc/init.d

Using CentOS 5.1 with Xen 3.2. I'm trying to install a fully virtualized system for the first time and doing this with an old Suse 9.0 (this probably would run paravirtualized, maybe it won't run, anyway, because of hardware problems). I start with virt-manager and after choosing "fully virtualized" it presents me two options for install media: iso image and CD-ROM or DVD,
