Issue with NFS 4.1 mount + JIRA DC 8.20.11

[Krishna Manthina]

OS: Centos 8.5.2111

Is anyone facing any issues where - jira.shared.home is set to a NFS Mount path in the DC Installation.

We created a user for JIRA, Say 'Jirauser' and installed the software with Jirauser.

What is observed by us is - 

1. Jira as a standalone installation works fine.

2. upon adding cluster.properties and setting the shared home path (& restart), JIRA is able to create directories as needed in the shared home.

3. When JIRA is further restarted, we are seeing permissions issues and the start-up page of jira shows an error that permissions are missing for jira.home

Note:

We tried chmod & chown on these 3 directories recursively - 

Installation Directory, JIRA Home, Shared Home as mentioned here - https://confluence.atlassian.com/jirakb/how-to-fix-directory-permissions-in-linux-for-jira-server-829048437.html

Note: When we run this with root user everything goes well.

We are not inclined towards running JIRA / other tomcat apps using root user.



UPDATE:::
This is resolved. 

Strangely, it seems to be a NFS version issue and this article helped us. 
https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/managing_file_systems/configuring-an-nfsv4-only-server_managing-file-systems . Not sure how root was earlier functional, but this is now working with all users.

 Krishna,

The issue is related to NFS Mount. check the NFS version used while mounting the disk.

• NFS 4.1 from the document is not enabled by default .
• Enable the version 4.1 in /etc/nfs.conf under section [nfsd]
• Restart NFS systemctl restart nfs-server
• Now try the mount with version 4.1mount -t nfs -o rw,nfsvers=4.1,lookupcache=pos,noatime,intr,rsize=32768,wsize=32768,_netdev
• check file permissions and mount path  and restart Jira

Thanks,

Praveen.
