LVM on large partitions greater than 2TB
by t m 05 Feb '07

05 Feb '07

I want to create one large LVM volume on the 2.5TB device. I seem to be able to create an LVM physical volume on the whole device, but I've read that it's better to create a single large partition for LVM as the existence of the partition informs other apps that the disk is in use which prevents accidental corruption of the LVM volume. Creating a large partition of this size under Centos is proving to be surprisingly difficult. I am unable to get fdisk to see more that 513GB on the whole unit, and once I create one 513GB partition, I can't create any additional partitions ("no sectors available"). I've read that fdisk has trouble with large partitions and that the GNU parted program should be used instead. Problem here is that GNU parted doesn't know about many file systems and doesn't know anything about LVM. So, following some steps on the LVM Howto, I used parted to create a large ext2 partition, then used fdisk to change the type to 8e for LVM. Once I do this, I see that the partition is now 2TB in size -- close, but .5 TB short. Why is this so difficult? How should large partitions be created under Centos? Any help is appreciated. Tom

APM and suspend to swap
by Robert Moskowitz 05 Feb '07

05 Feb '07

I have been delving into how to get this HP NC4010 to suspend. I think the practice of just closing the unit for 15+ min inside my backpack as I move to the next meeting is what cooked my drive... So it seems that Debian users have been successful with APM: http://www.proulx.com/~bob/nc4000/ and http://www.gag.com/~bdale/nc4000/ So my Centos related questions are: I need to turn acpi=off in the boot so I can turn on apm. How DO I turn on apm. I have a large enough swap drive. It is an LVM drive of 2Gb and I have 768Mb memory. The example given is: vmlinuz-2.6.8.1-1+8-686 root=/dev/hda5 ro acpi=off resume2=swap:/dev/hda1 My swap drive is: /dev/mapper/VolGroup00-LogVol00 what do I do above? and my root is /dev/mapper/VolGroup00-LogVol01 There are references to compling the kernel. Do I have to do that? Is that mkinitrd? what suspend command do I use? What do I loose giving up acpi? thanks. I am leaving for the RSA conference in San Fran tomorrow morning, so I would really like to get this going...

Centos 4.0 updates repo & local repository creation
by Sanjay Arora 04 Feb '07

04 Feb '07

Hello all I used Centos 4.0 iso to setup my systems and updated till date. I assume they are equivalent to systems created with Centos 4.4 Now, I am planning to setup a full local repository of Centos updates, extras, centosplus etc. (not isos...as I intend to download isos only when Centos 5 becomes available. Please advise what directories I should download for my local repository, as the download tree has updates, extras, centosplus repos for 4.0, 4.1, 4.2, 4. & 4.4 & so on. Please advise the appropriate rsync commands, so that I can use it, so as to exclude isos and include the rest. A smal comment on how the repos relate to version numbers would be really appreciated. With best regards. Sanjay.

Maildir Cleanup
by Jun Salen 03 Feb '07

03 Feb '07

Hi all, I found an article (with python script) on how to clean up Maildir folder for old email messages from http://www.ducea.com/2006/11/25/cleanup-maildir-folders-archive-delete-old-… . As I understand, this will be run by each user after login. How can I make this runs at least once a month and delete all users message with age more than one month for example using crontab? I am using Postfix, MailScanner, SpamAssassin, Courier IMAP/POP3, ClamAV and CentOS4.4 as mail server. If you need further input, please just let me know. Thanks in advance for help.
