Hello...
Is there any documentation on Clustered NFS on Oracle RAC? I have been looking around and so far only found the section(6) in the SFCFS Admin guide 5.1, however I am wondering if that's the only documentation spefically for configuring it.
Alternatively if anybody has any other config documents/links that would be great.
Thanks.
Solved! Go to Solution.

Hi,
The https://sort.symantec.com/documents site has all the documentation, LBN's, man pages, HCL's, etc.
) Not sure what you mean by Clustered NFS. Most folks use SF-RAC with failover NFS but we have new products with parallel shares. Is it one of these?
-- Clustered CNFS is an option in SF-CFS in 5.1SP1.
CNFS shares SF-CFS parallel mounts from all nodes for CIFS and/or NFS.
(Note: Oracle CRS/RAC is not supported on SF-CFS 5.1sp1rp1, only SF-RAC 5.1sp1rp1.)
-- Regular SF-CFS/SF-RAC can share the parallel mounts from a single node, and failover the share. This is a good environment where the storage failover isn't fast enough, or the NFS/CIFS share data with a parallel application like SF-RAC.
-- SF-HA supports failover mounts with failover NFS and CIFS shares.
-- There is also the 5.6 FileStore product which does parallel CIFS shares from parallel mounts using ctdb. (This is available only on Symantec Linux platform. Please contact sales for more information on FileStore.)
- The SF-RAC product is also available for 5.1SP1 and supports failover NFS and possibly the parallel NFS shares. You would need the SF-RAC training classs, Sales Engineering and/or Technical support to know if they can be installed on the same system.
) There are a number of client side issues with parallel shares:
- Failover NFS/CIFS works easist with clients as the VIP and NFS locks failover if the server fails.
- On parallel shares, whether or not the clients failover is up to the client environment.
- Our solutionis do not include IP load balancing or IP redirection.
- CIFS has similar issues with NMB registration.
Thank you,

Ideally, we refer to the SFCFS Admin guide for configuration.
Can you send us details about your environment like Platform, Hardware , version of the operating system (Are you planning to implement this on Virtual environment like VMWARE or physical hardware )etc... ?
Thanks,

Thanks for the info.
Server info;
5.10 Generic_142900-09 sun4v sparc SUNW,Sun-Fire-T2000
VRTSvxfs | PSTAMP: 5.1.100.000-5.1SP1-2010-10-04-VERITAS-FS-142634-05
VRTSvcs | PSTAMP: 5.1.100.000-5.1SP1-2010-09-30_23.30.00
Ultimately I want to NFS share a mount from the two node cluster and be resilient against server failure on one of the nodes. I think that this may be the option Pam suggested;
-- Clustered CNFS is an option in SF-CFS in 5.1SP1.
CNFS shares SF-CFS parallel mounts from all nodes for CIFS and/or NFS.
(Note: Oracle CRS/RAC is not supported on SF-CFS 5.1sp1rp1, only SF-RAC 5.1sp1rp1.)
I am using the Best practice doc from Symantec;
http://eval.symantec.com/mktginfo/enterprise/white_papers/b-veritas_storage_foundation_cluster_file_system_5_1.en-us.pdf
Are there any others, or experience of using this would be good.
Thanks.
