Problem Summary
For a customer, I was doing the prechecks for his VCF environments, since we wanted to upgrade the environments from 3.9.1. to 3.10. Unfortunately the following error appeared on all 3 environments.
Error Description:
LCM does not have read/write permission to /opt/vmware/vcf/lcm/lcm-app/conf/jpa-prod.properties.bak
Proposed Remediation:
Make sure LCM App user (vrack) has read & write permissions to all files & directories involved in LCM self-upgrade
Troubleshooting
*********************Precaution************************
Before you start with this procedure, please make a snapshot of your SDDC-Manager first.

So the folder were we need to be is:
/opt/vmware/vcf/lcm/lcm-app/conf/
Here, there will be a few files that we need to change the permission from.
As you see below, these are the permissions before the change.
In the precheck error, it stated that it couldn’t access the file “jpa-prod.properties”.
For all the coming precheck file errors, we will be changing the permissions of the “Group” & “Other Users”.
If correct, the Owner already has the highest permissions (7). The following command will change the permission to:
776 otherwise known As
Owner: Full Permissions (7), Group: Full Permissions (7), Others: Read & Execute Permissions (6)
So the first file we’re going to change with the command is the “jpa-prod.properties” file.
Chmod 776 jpa-prod.properties
After that the precheck still failed, but if you look closely, this time it fails on a different file.
Error:
LCM does not have read/write permission to /opt/vmware/vcf/lcm/lcm-app/conf/application.properties
Chmod 776 application.properties
After that Change the last precheck error came along
So for we change the permissions one more time with
Chmod 776 VersionAlias.yml.old
After that the Issue was solved and the Precheck Succeeded.
The File Permissions in the End looked like this.
Hope that this was helpfull for you.
