resize LVM (ext3)
by David Hláčik 31 Oct '08

31 Oct '08

Hello guys, my scenario is following 1. I have LVM group named "system" 2. I have a logical volumes - system/root , ext3 mounted as / (20GB) - system/swap, swap - system/home, ext3 mounted as /home (431GB) I need to shrink system/home to 80GB (currently there is 57GB used) and use free space to create another logical volumes. My scenario is 1. reduce ext3 fs size to 80GB by using resize2s 2. reduce system/home size by using lvreduce 3. create another logical volumes Questions 1. How can i be sure that i will shrink ext3 to exact size 80GB and that the same will lvreduce do? I do not want to cut from ext3 filesystem if i will reduce logical volume too much 2. Can you please send me commands to achieve 1) and 2) part of my scenario? 3. Or can i just use lvreduce and my ext3 will shrink automatically? 4. Do i need to umount system/home when resizing? Thanks in advance! David

Apparently no swap configured

Is that good enough confirmation that it is not in use? I'm very curious how I managed to get into this situation, using the GUI install method. Any ideas on that? I'd prefer not to be in this situation again. Thanks Ian Masters

Desktop Choice Centos 4/Centos 5 or Fedora 9
by vandaman2002-rt＠yahoo.co.uk 30 Oct '08

30 Oct '08

I have a choice of CentOS 4/5 and Fedora 9 on a laptop. I have not use CentOS 5 on a desktop but have used CentOS 4 and Fedora 9. I found the Fedora Gnome not as appealing as the CentOS 4 clearlooks. Any opinions from someone who has used CentOS 4/5 and Fedora? I'm not a KDE fan so KDE users need not reply. Regards, Vandaman.

We are seeing very similar behavior. It has gotten better since we complained to IX but we still see a significant lag the first time the site loads. The fast load on subsequent visits could be explained by Drupal doing some caching of needed items so it doesn't have to go to the database. The initial site load time became much more noticeable after IX took some kind of hit on their DB server. All we know is the site suddenly couldn't connect to the database, they fixed something on their end and the database came back but we've had the long lag for first load ever since.

changing partition priority on install
by Monty Shinn 30 Oct '08

30 Oct '08

Greetings. I am in the process of installing 5.1 64 bit on a server. The server has 2 3ware cards: 9550SX 12 port, and a 8006 2 port, both SATA. I want the 8006 board to be /dev/sda, and the 9550 to be /dev/sdb. My plan is to install the os on /dev/sda (8006), and data on /dev/sdb (9550). Unfortunately, the 9550 comes up as /dev/sda. The 8006 is installed in slot 3, which is a 100Mhz slot. The 9550 is installed in Slot 4, which is a 133Mhz slot. I really don't want to put the 9550 in the 100Mhz slot. I'm not even sure it would make a difference... I would also prefer to not have grub reside on /dev/sda, while the os is on /dev/sdb. I have tried to change the boot priority in bios, but this hasn't changed the priority. I tried to disable one of the boards in the bios, but that didn't seem to have any effect. Interestingly enough, when I boot with the Knoppix 5.1.1 live cd, the cards show up as I want them to. I have searched Google, but I am either entering the wrong search parameters, or there isn't anything out there, at least pertaining to the initial installation. Any ideas are appreciated. Thanks in advance. Monty Specs: Supermicro X6DH8-G 3ware 8006-2lp pci-X 3ware 9550sx-12, pci-X CentOS 5.1, x86_64, network (nfs) install

RHEL 5.3 Beta released, beta-testers needed
by Dag Wieers 30 Oct '08

30 Oct '08

Hi all, The CentOS community is pretty limited in what we can do to the core distribution. Since our mantra is "aiming to be 100% compatible with Red Hat Enterprise Linux" we cannot fix bugs or improve the CentOS core without waiting for Red Hat to make those modifications first. We have limited leverage and a 6-month release cycle against us. But that is not the complete truth, Red Hat usually has an internal, a vendor and a public beta period and everything that is found within that time-frame might get fixed before it is being shipped (and frozen) for the next 6 months. Today RHEL 5.3 Beta was announced with a lot of interesting improvements. https://www.redhat.com/archives/rhelv5-announce/2008-October/msg00000.html So if we can improve the testing during the RHEL Beta program, everyone in the CentOS community directly benefits from that as well. Therefor it makes a lot of sense to encourage the large CentOS community to take part in the RHEL Beta program and help with improving the next CentOS releases. (You don't need my back patting, start already !) If you are looking for the RHEL 5.3 Beta ISO images, go to Red Hat Network, log in, click on Download Software, expand the RHEL5 channel for your architecture and go to the Beta channel. There you can find the RHEL 5.3 Beta ISO images for your architecture. https://rhn.redhat.com/rhn/software/channel/downloads/Download.do?cid=6002 https://rhn.redhat.com/rhn/software/channel/downloads/Download.do?cid=6007 And please, if you find anything that is worth to fix, report your findings to Red Hat's bugzilla. Thanks in advance, -- -- dag wieers, dag(a)wieers.com, http://dag.wieers.com/ -- [Any errors in spelling, tact or fact are transmission errors]

A few general questions
by kevin kempter 30 Oct '08

30 Oct '08

Hi All; I ran Linux as my main laptop OS for several years, then I got into a mac shop and bought a macbook. The macbook is ok but it just doesn't cut it per productivity so I've ordered another laptop (a 64bit laptop with 8G of memory expandable to 16G and 2 internal 320G 7200rpm drives) I'll be loading Linux as soon as the machine arrives from Dell. Here's my questions: 1) Are there any published plans for CentOS to support KDE4, or is there a way to upgrade CentOS to KDE4 ? 2) Does anyone know if Kpilot is working with Palm Centro phones ? Is there a better solution besides Kpilot ? 3) Does Kmail support Exchange yet ? 4) Is there a way to migrate apple mail messages to Kmail ? 5) Is there a way to migrate apple address book and calendar events to the KDE address book and calendar ? Thanks in advance...

Re: [CentOS] Can one invoke multiple INSTANCEs of Firefox on CentOS

This works. Thank you. The magical invocation is: Edit ~/.bashrc or /etc/bashrc and add: # Force Mozilla (Firefox) to prompt for profiles # and start as separate instances for each. MOZ_NO_REMOTE=1; export MOZ_NO_REMOTE # Then invoke via "firefox -SelectProfile %u" Log out and restart the desktop to get the changes to take effect for the panel and menus. Changes made to ~/.bashrc or /etc/bashrc are picked up with each new terminal window opened and do not require a logout or source command if you invoke Firefox from the command line instead. Many thanks. Now I can lose myself in the madness of model-model, view, controller xml.... wheeeee.... -- *** E-Mail is NOT a SECURE channel *** James B.

I went to the Mozilla Firefox Help page and read up on this. However, when I run: # firefox -ProfileManager All I get is a new Firefox window with all of the bookmarks and history of my standard user profile.
