Description of problem: In System Administration guide, there are a lot of improvement point. The current guide will cause massive support cases related to installation. These are my suggestions. 1. Between chapter 3 and chapter 4, we should have a summary of installation step or overview of the installation. Current guide structure has a difficulty to understand the overview and readers will not be able to understand what they actually do and what they should do in the next. 2. Before chapter 4, we should have subscription attach procedure for RHUA, CDS, HAPROXY. Currently, the reader does not understand what repositories and subscription need to be attached in each role. 3. In section 4.1, we have following command. ~~~ # subscription-manager register --type=rhui ~~~ If the system is registered as type=rhui, the system can not be enabled rhel-7-server-rpms repository. I think this procedure should not be written in the guide. Instead, we should have a step to create a RHUI unit via Customer Portal. 4. In section 5.2, we have ~~~ 2. Add the following entry in /etc/fstab on each CDS node. /dev/xvdb /export/xvdb xfs defaults 0 0 ~~~ In this line, we have /dev/xvdb as an example. But the above of the line, we have following lines. ~~~ [root@cds1 ~]# yum install glusterfs-server glusterfs-cli rh-rhua-selinux-policy [root@cds1 ~]# mkfs.xfs -f -i size=512 /dev/vdb [root@cds1 ~]# mkdir -p /export/xvdb; mount /dev/vdb /export/xvdb; mkdir -p /export/xvdb/brick; chkconfig glusterd on; service glusterd start ~~~ So we should modify the line like as below. ~~~ /dev/vdb /export/xvdb xfs defaults 0 0 ~~~ Document URL: Section Number and Name: Describe the issue: Suggestions for improvement: Additional information:
In Chapter 5, ~~~ [root@cds1 ~]# yum install glusterfs-server glusterfs-cli rh-rhua-selinux-policy [root@cds1 ~]# mkfs.xfs -f -i size=512 /dev/vdb [root@cds1 ~]# mkdir -p /export/xvdb; mount /dev/vdb /export/xvdb; mkdir -p /export/xvdb/brick; chkconfig glusterd on; service glusterd start ~~~ This step assumes CDS is RHEL6. We should have RHLE7 version like ~~~ [root@cds1 ~]# yum install glusterfs-server glusterfs-cli rh-rhua-selinux-policy [root@cds1 ~]# mkfs.xfs -f -i size=512 /dev/vdb [root@cds1 ~]# mkdir -p /export/xvdb; mount /dev/vdb /export/xvdb; mkdir -p /export/xvdb/brick; systemctl enable glusterd.service; systemctl start glusterd.service ~~~
