I use keepalived/lvs. Yes, you need to install it. Otherwise, there's no
way for you to manage the lvs function?
At least, that's what I've been led to believe...

Assuming I understand you correctly, and assuming you have an init.d script
in place, run this command:
grep daemon /etc/init.d/keepalived
Odds are, you're editing /usr/local/etc/keepalived.conf, but the init.d
script starts keepalived and tells it to use /etc/keepalived.conf
?

Re: [CentOS] Ext4 on CentOS 5.5 64bit
ext4 better then ext3 ! you can install ext4 by yum see: https://ext4.wiki.kernel.org/index.php/Ext4_Howto#Compatibility 2010/12/23 cpol...@surewest.net Matt wrote: Is ext4 stable on CentOS 5.5 64bit? I have an email server with a great deal of disk i/o and was wandering if ext4 would be better then ext3 for it? Before committing to ext4 on a production server, it would be good to consider the comments made in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/317781/comments/45 which presumably still apply to current CentOS 5.5 64-bit kernels. As I read it, Ts'o argues that the apparent loss of stability compared to ext3 is a design issue in the realm of applications that run atop it. I hope this is not a misreading. -- Charles Polisher ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
