Description (partial)

Hosted Collaboration Mediation - Fulfillment (HCM-F) 10.0.x-to-10.1.x upgrade sometimes fails due to the inability to create semaphores. The error shown in the install log is not very clear and shows following messages:|File:/opt/hcs/sdr/bin/, Function: checkDB(), SDR DBMS is not running. Please start and retry.|<LVL::Error>|File:/opt/hcs/sdr/bin/, Function: create_users(), SDR create database users error 1|<LVL::Error>|File:/opt/hcs/sdr/bin/, Function: main(), SDR 20 error 1|<LVL::Error>

This can actually be the indication of semaphore related issue; to confirm this, do the following in shell:
1.	chroot  /partB

2.	Then look at the file /opt/hcs/sdr/logs/SDR_10_<version>.txt
           If the file contains info like below, then this indeed is an issue resulting from the inability to create semaphores:
"2014-10-08 14:55:58 PDT:::::[19456]: FATAL:  could not create semaphores: No space left on device
2014-10-08 14:55:58 PDT:::::[19456]: DETAIL:  Failed system call was semget(5435062, 17, 03600).
2014-10-08 14:55:58 PDT:::::[19456]: HINT:  This error does *not* mean that you have run out of disk space.  It occurs when either the system limit for the maximum number of semaphore sets (SEMMNI), or the system wide maximum number of semaphores (SEMMNS), would be exceeded.  You need to raise the respective kernel parameter.  Alternatively, reduce PostgreSQL's consumption of semaphores by reducing its max_connections parameter.
The PostgreSQL documentation contains more information about configuring your system for PostgreSQL."

3.	exit out of /partB by issuing the command : exit
