BOS Connector Remains in Status Indexing 
The status of an SAP BO Search connector remains in the status Indexing for a long period of time and the SAP NetWeaver Enterprise Search ABAP system does not respond.
This may be due to the fact that the data area of the MaxDB is full because a high volume of data was extracted from the back-end system during the initial load. If the data area is full (no space left on the data volumes), the application is suspended - you do not see any progress anymore. All database tasks are suspended until space is available again.
You can solve this problem by adding data volumes. The new data volume can be added in operational state ONLINE and can be used immediately. All suspended tasks continue their work as soon as the ADD VOLUME is finished.
Log on to your ABAP system as the <sid>adm user.
Check the existing volumes with the following command:
dbmcli -d <database_name> -u <dbm_user>,<master_password> param_getvolsall
In this case, the <database_name> is the SAPSID of the SAP NetWeaver Enterprise Search system that was assigned during the installation.

There are the following possible ways to add a new data volume:
You can add a new data volume in .
You can also use the following DBMCLI command:
dbmcli -d <database_name> -u <dbm_user>,<password> db_addvolume DATA <volume_name> <volume_type> <volume_size>
<volume_name> is the complete path including the file name of the new data volume.
<volume_type> is the device type: F (file), R (raw device), or L (link).
<volume_size> is the size of the volume to be added in pages (1 page = 8 KB).
