Re: [Pacemaker] DRBD with Pacemaker on CentOs 6.5
Hi, I'm fluent in English so I doubt it's a language barrier. I have reasonable user experience in Linux, though not extensive experience in the various system commands, and I have zero experience in HA. I'm in fact trying to make things as simple as possible by simply following the Clusters from Scratch guide step by step, and only modifying/omitting steps when they don't work. I know a block device (like /dev/sda) is simply a device (such as a hard disk) that appears like a file in Linux, allowing users buffered access to the device. I know a file system is like FAT/NTFS/ext2/etc. I know a mount point is a directory that you can mount an image file with a file system onto it. Once mounted, it would be as if the entire file system has the mount point as its root directory. I set up DRBD almost exactly like the instructions from Chapter 7 of Clusters from Scratch. The only differences are in our setups. The guide assumes Fedora 13, DRBD 8.3 while I'm using CentOS 6.5 and DRBD 8.4. Since I was following the guide from start to finish, /var/www/html already has index.html already in there. node01 has it's own index.html, and node02 has its own index.html, both with different content. The guide did not instruct me to delete these files, and seems to configure the mount point to be /var/www/html (Chapter 7.4) with an ext4 file system, hence mounting the image onto a directory that already has files in it. Is this a problem?

I'm unsure if there is just a language barrier, or if you just have not enough experience with linux in general, or if you try to make things more complicated as they are. Do you know * what a block device is? * what a file system is? * what a mount point is? * that a mount point may not be empty, even though it typically is? * what it means to mount a file system to a mount point? Assuming you set up DRBD in a sane way, and it is mounted on *one* node (the node where it is Primary), then on the *other* node, where it is NOT mounted, you will only see the mount point, and whatever happens to be in there. You probably should clear out the contents of that mount point, so that you'd have an empty mount point. Or, if you like, replace it with some dummy content that clearly shows that this is the mount point, and not the file system that is intended to be mounted there. Status URL is enabled in both nodes. As for the DocumentRoot must be a directory, please double check for typos...

Re: [Pacemaker] DRBD with Pacemaker on CentOs 6.5
Hi, No, I did not do this. I followed the Pacemaker 1.1 - Clusters from scratch edition 5 for Fedora 13, and in section 7.3.4 it instructed me to run the following commands, which I did: mkfs.ext4 /dev/drbd1 mount /dev/drbd1 /mnt create index.html file in /mnt umount /dev/drbd1 Subsequently, after unmounting, there were no further instructions to mount any other directories. So, how should I mount /dev/mapper/vg_node02-drbd--demo to /var/www/html? Should I be mounting /dev/mapper/vg_node02-drbd--demo, or /dev/drbd1. Since I've already created index.html in /dev/drbd1, should I be mounting that? I'm a little confused here.

Re: [Pacemaker] DRBD with Pacemaker on CentOs 6.5
By the way, you want to configure DRBD before you configure Apache. You start from the bottom up. Get a fully working platform upon which to build. Make sure that DRBD is working and that fencing is *in place and working*; DON'T SKIP THIS! Then build Apache on top of that. d.p.
