Symptom
On a distributed SAP HANA System, running on Single Database Container, database recover fails with the following error in backup.log:
RECOVERY RECOVER DATA finished with error: [110092] Recovery failed in
nameserver startup: convert topology failed, mismatch: 1
statisticsservers configured in source topology, 0 standby in source
topology, 2 in destination system, mismatch: 1 xsengines configured in
source topology, 0 standby in source topology, 2 in destination system
Meanwhile, if you check the daemon.ini file for different nodes on SAP HANA server, you'll see there're 2 nodes having the same content in their daemon.ini, for example:
cat hananode01/daemon.ini
[sapwebdisp]
instances = 1
[statisticsserver]
instances = 1
[xsengine]
instances = 1
cat hananode02/daemon.ini
[sapwebdisp]
instances = 1
[statisticsserver]
instances = 1
[xsengine]
instances = 1
