I've been testing Business Central (from PAM7.6) in Azure RHT Openshift (ARO).
In summary, HA Business Central is not feasible using Azure File (the RWX filesystem offered through Azure).
Recommendation: Document that Azure File is not a viable option for HA Business Central. The customer will need to seek an alternative RWX filesystem.
Specifics of my testing as follows:
1) BC (from PAM 7.6) using a RWO "Azure Disk" StorageClass for OCP4.* works well but does not provide HA
2) BC (from PAM 7.6) using a RWX "Azure File" StorageClass for OCP4.* does not start up. It chokes on the following line in jgit: https://github.com/eclipse/jgit/blob/v22.214.171.124807311906-r/org.eclipse.jgit/src/org/eclipse/jgit/util/FS_POSIX.java#L386
In particular, a hard-link is being attempted.
Azure File does not allow creation of a hard link as per: https://docs.microsoft.com/en-us/rest/api/storageservices/features-not-supported-by-the-azure-file-service (in contrast, a soft link is possible).
