Bug 1318119

Hi Soumya,

Can you please share the steps to setup gluster-NFS server using CTDB. If the steps are documented in any kbase articles / google docs you could share too for me to begin the documentation process.

I have never done the CTDB setup before. I request Niels to provide the notes.

Please see the documentation for RHGS-2.1:

  9.5. Configuring Automated IP Failover for NFS and SMB

  https://access.redhat.com/documentation/en-US/Red_Hat_Storage/2.1/html-single/Administration_Guide/index.html#sect-Configuring_Automated_IP_Failover_for_NFS_and_SMB

Hello Niels,

The Section 9.5.2. Starting and Verifying your Configuration, has more SMB specific steps. Can you please share the steps that are more relevant to NFS?

https://access.redhat.com/documentation/en-US/Red_Hat_Storage/2.1/html-single/Administration_Guide/index.html#sect-Configuring_Automated_IP_Failover_for_NFS_and_SMB

Also, do I need to make any changes to Section 9.5.1. Setting Up CTDB, or are the same steps relevant to RHGS 3.1 too ?

Thanks,
Bhavana

The basic CTDB configuration is the same for Samba and NFS. If those are the steps discussed with the Samba team, I don't have any objections.

Thanks!

Hello Talur,

We are adding a section in the NFS chapter about setting up gluster-NFS cluster using CTDB.

Niels and I would want to check with you if the steps mentioned under Section 9.5.1. Setting Up CTDB (this was in the RHS 2.1 doc) are relevant now (RHGS 3.1) or are there any changes to these steps, wrt version numbers etc ?

RHS 2.1 Admin Guide: https://access.redhat.com/documentation/en-US/Red_Hat_Storage/2.1/html-single/Administration_Guide/index.html#sect-Configuring_Automated_IP_Failover_for_NFS_and_SMB

Refering to https://access.redhat.com/documentation/en-US/Red_Hat_Storage/3.1/html/Administration_Guide/sect-SMB.html#idp11726848 

You can use section 7.3.1. Setting up CTDB for Samba as template and have a new section 7.2.1 in NFS as Setting up CTDB for NFS. Some of the changes would be

1. Replace Samba with NFS in all points.
2. Step 3 
In the /etc/samba/smb.conf file add the following line in the global section on all the nodes:
is not relevant but you should have some equivalent of it for NFS.


You might find https://ctdb.samba.org/nfs.html useful when writing NFS specific points.

Thanks Talur!

Hi Niels,

I have added a new section 7.2.1. Setting up CTDB for NFS in the administration guide.

http://jenkinscat.gsslab.pnq.redhat.com:8080/view/Gluster/job/doc-Red_Hat_Gluster_Storage-3.1.3-Administration_Guide%20%28html-single%29/lastBuild/artifact/tmp/en-US/html-single/index.html#idm140442587255728

As talur suggested, i have removed step 3 from the procedure. Let me know if there is any alternate step for NFS.

Also, do let me know if there are any other changes required for this section.

Thanks,
Bhavana

Looks good to me, I do not think there are any further changes needed. Thanks!

Thanks Niels.


Moving the bug on_qa

*** Bug 1280021 has been marked as a duplicate of this bug. ***

Bhavana,

I still see lots of reference given to samba servers in NFS setup section which may create confusion. 
Action:
Remove references to samba servers in ctdb with nfs setup.

Hi Surabhi,

I have made the changes where required. 

http://jenkinscat.gsslab.pnq.redhat.com:8080/view/Gluster/job/doc-Red_Hat_Gluster_Storage-3.1.3-Administration_Guide%20%28html-single%29/lastBuild/artifact/tmp/en-US/html-single/index.html#idm140668379427488

Thanks

The doc looks good now. Moving to verified.
