Advice on setting up Raid and LVM
by Fajar Priyanto 02 Mar '06

02 Mar '06

Hi all, I'm setting up Centos4.2 on 2x80GB SATA drives. The partition scheme is like this: /boot = 300MB / = 9.2GB /home = 70GB swap = 500MB The RAID is RAID 1. md0 = 300MB = /boot md1 = 9.2GB = LVM md2 = 70GB = LVM md3 = 500MB = LVM Now, the confusing part is: 1. When creating VolGroup00, should I include all PV (md1, md2, md3)? Then create the LV. 2. When setting up RAID 1, should I make those separated partitions for /, /home, and swap? Or, should I just make one big RAID device? The future purpose of using LVM is I want to be able to expand any partitions that would run out of space into a new disk. Thank you very much. -- Fajar Priyanto | Reg'd Linux User #327841 | Linux tutorial http://linux2.arinet.org 18:35:53 up 4:55, 2.6.15-1.1830_FC4 GNU/Linux Let's use OpenOffice. http://www.openoffice.org

index.php test
by Robert Hanson 02 Mar '06

02 Mar '06

greetings i just noticed in another thread the index.php <?php phpinfo(); ?> reference... when you put this on a current i386 centos 4.2 server and hit that page, of course it spews a bunch of info. does anyone have any recommended websites or docs to cross reference or compare this "specific info" against to determine if "obvious" security modifications should be made?? thanks in advance for your help! - rh -- Robert Hanson - Abba Communications Computer & Internet Services (509) 624-7159 - www.abbacomm.net

Dmesg errors logged
by Sam Drinkard 02 Mar '06

02 Mar '06

Along with the discussion of system loading, I remembered something I wanted to add, but just remembered it. I noticed when I logged out, there was a brief flash of a text page (console I presume) that had some things I wanted to investigate further. Given it is a rather lengthly text file, and rather than clutter up the pages here, I stuffed it on my server so anyone wishing to look at it and comment can do so. The file is available at http://wa4phy.net/dmesg.txt Lots of segfaults I know which application they came from, but I don't quite understand about the keyboard errors and emulating rawmode for keycode 240. There also appears to be a few disk errors, both in buffer I/O and a few others I have no idea what they are. At any rate, would appreciate any comments, or if something needs a tweak, that too. Sam

It depends on how Vim recognizes the file. If Vim displays the file as a DOS file, it will hide the ^M and you can't search for it. If Vim displays the file as a unix file, it will show the ^M at the end of the line and you can search and replace it with the command shown above. -- Bowie

Checking out yum localinstall before installing
by Robert Moskowitz 02 Mar '06

02 Mar '06

I want to just see what will happen (ie success, or some dependencies still cannot be met) with: yum localinstall whatever.rpm I ASSuME (I have googled for this, but it is not clear) that localinstall will take the rpm, install it, and go to the yum repro to meet any outstanding dependencies. I just want to test this right now, not actually do it. I want to know what yum would install from the repro as well.

Discrepancies in Anaconda-ks.cfg after kickstart
by Robert Moskowitz 02 Mar '06

02 Mar '06

I am asking this here, that although a kickstart question, may have something to do with the Centos install? I took my Anaconda-ks.cfg from my system, turned it into a ks.cfg and did the install. Everything SEEMS ok, but why? First the partitioning information: ks.cfg supplied: clearpart --all --drives=hda part /boot --fstype ext3 --size=100 --ondisk=hda part / --fstype ext3 --start=14 --end=796 --ondisk=hda part pv.34 --start=797 --end=2303 --ondisk=hda part swap --start=2304 --end=2434 --ondisk=hda volgroup VolGroup00 --pesize=32768 pv.34 logvol /var/opt/scalix --fstype ext3 --name=Scalix --vgname=VolGroup00 --size=8192 anaconda-ks.cfg reports: clearpart --all --drives=hda part /boot --fstype ext3 --size=100 --ondisk=hda part / --fstype ext3 --start=14 --end=796 --ondisk=hda part pv.100000 --start=797 --end=2303 --ondisk=hda part swap --start=2304 --end=2434 --ondisk=hda volgroup VolGroup00 --pesize=32768 pv.100000 logvol /var/opt/scalix --fstype ext3 --name=Scalix --vgname=VolGroup00 --size=8192 what is happening here? Just putting the partitions in different locations, but the same size? Or just reporting differently? Now for packages. ks.cfg %packages @ office @ admin-tools @ editors @ emacs @ system-tools @ text-internet @ dns-server @ gnome-desktop @ dialup @ network-server @ smb-server @ base-x @ web-server @ printing @ kde-desktop @ mail-server @ server-cfg @ development-tools @ graphical-internet system-config-samba system-config-httpd kernel mailman grub kernel-devel system-config-printer -openoffice.org ethereal-gnome -planner openldap-servers krb5-server iptraf -openoffice.org-libs gftp lvm2 freeradius -spamassassin gnome-nettool system-config-printer-gui -sendmail-cf vnc nmap-frontend e2fsprogs -dovecot -openoffice.org-i18n thunderbird and anaconda-ks-cfg: %packages @ office @ admin-tools @ editors @ emacs @ system-tools @ text-internet @ dns-server @ gnome-desktop @ dialup @ network-server @ emacs @ smb-server @ base-x @ web-server @ printing @ kde-desktop @ mail-server @ server-cfg @ development-tools @ graphical-internet kernel grub kernel-devel -openoffice.org -planner -openoffice.org-libs lvm2 -sendmail-cf e2fsprogs -dovecot -openoffice.org-i18n Wow! is the installed list shorter than the 'asked' list. Or is it, perhaps the same way to report the same actions? How would I know?

I thought it took their presence as the hint to > display in DOS mode. A screwed-up text file that doesn't have the ^M's on every line will display this way in Vim. This tends to happen when you transfer a DOS file to unix and then edit it with a program that does not do the conversion for you. The resultant file has ^M at the end of every line except ones you added with the unix editor. -- Bowie

Updates on Centos 4
by Dexter Stowers 01 Mar '06

01 Mar '06

Hi, I have a server that has been running Centos for about a year but I have not checked to see if there have been any changes to update. Has there been any updates or fixes for the update? I have not been in the loop for a while now. Thanks! -- Dexter Desire is the ingredient that changes the hot water of mediocrity to the steam of outstanding success.
