Bug 2024878

Discussion of this issue as taken place elsewhere so I am summarizing the status on the BZ (I'm a little late in doing this, the discussion took place several weeks ago).  

I brought this up at the Cluster PM meeting, and as expected there is general agreement that this is a good idea although not of immediate high priority.  Although the change seems simple enough (it's basically a matter of one mkfs command, and subsequent output to reflect that, but no change to the procedure steps), it will involve not just a documentation update but testing each updated procedure (there are a few of them that use the ext4 file system).  This brings in the QE department, which doesn't have the capacity to do this in the 8.6/9.0 time frame (however simple it is). 

We plan to make these updates, but we will start working on them once 8.6 and 9.0 are settled.  Again, this is definitely a good idea and we will work it into our plans.

Thank you Steven.

Not an urgent one and can be dealt with after 8.6 and 9.0 are settled.

Exchange with Abhi Das on 1/4/22:

<slevine> abhi: I have a really basic file system question that has nothing to do with the Clustered Samba procedure, but I think you can help:
<slevine> When we first wrote up all the cluster (and LVM) procedures, we used ext4 file systems. But our default file system has been xfs for a long time now, so I have a ticket to update our examples
<slevine> I think this should be trivially easy – use mkfs.xfs instead of mkfs.ext4
<slevine> As in the final step of this example at the end of section 6.1 in the cluster title: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html-single/configuring_and_managing_high_availability_clusters/index#proc_configuring-lvm-volume-with-ext4-file-system-configuring-ha-nfs
<slevine> So I think all I need to do is run the examples with mkfs.xfs and update the output
<slevine> Is it that simple? I know there are many options, but for the equivalent of what we provide now for ext4 it seems we don't really need them.
<abhi> yes, mkfs.xfs will work as expected

The published documentation cluster configuration example now use XFS file systems.

The file system configuration is here:
RHEL 8
https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html-single/configuring_and_managing_high_availability_clusters/index#assembly_configuring-active-passive-http-server-in-a-cluster-configuring-and-managing-high-availability-clusters

RHEL 9
https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/9/html-single/configuring_and_managing_high_availability_clusters/index#proc_configuring-lvm-volume-with-ext4-file-system-configuring-ha-http

I did not change the name of the module in source because that would have broken all links, but it doesn't affect the actual published documentation.

I also updated all references to this procedure and all references to configuring an ext4 file system.

This also involved updating the section on configuring a cluster using System Roles:

RHEL 8
https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html-single/administration_and_configuration_tasks_using_system_roles_in_rhel/index#configuring-http-ha-using-system-roles_configuring-ha-cluster-using-system-roles

RHEL 9
https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/9/html-single/administration_and_configuration_tasks_using_system_roles_in_rhel/index#configuring-http-ha-using-system-roles_configuring-ha-cluster-using-system-roles

Thank you Steven. The updated docs look good.
