3382908 - Replication Synchronization via delta is not possible even though logshipping_max_retention_size is largely configured


You get issues during Replication Synchronization. Below errors are observed in HANA trace: 

[xxxxx]{-1}[-1/-1] xxxx-xx-xx xx:xx:xx.xxxxx w sr_dataaccess    DisasterRecoveryProtocol.cpp(02237) : Synchronization via delta is not possible, reason: the secondary has probably been disconnected for a relatively long time, that the primary has reached the configured limit or disk space limit for log retention
[xxxxx]{-1}[-1/-1] xxxx-xx-xx xx:xx:xx.xxxxx w sr_dataaccess    DisasterRecoveryProtocol.cpp(02238) : Please check if enable_log_retention is set to 'off' on primary; or if logshipping_max_retention_size on primary is not big enough; or if Disk/Log volume is full on primary, for more information please check 'Log Retention' section in administration guide.

You have already increased logshipping_max_retention_size to (for example) 2TB for the affected service and set the value '2,097,152' (value in MB). 

However, the errors still occur as before.
