Problem IC66949 Status: Closed

AFTER ALTER TABLESPACE REDUCE ON DMS TABLESPACE, "DF -K" ON THE
VERITAS FS (VXFS) STILL SHOWS SPACE NOT RELEASE BACK TO OS.

product:
DB2 FOR LUW / DB2FORLUW / 910 - DB2
Problem description:
After issuing the ALTER TABLESPACE ... REDUCE command on the 
DMS tablespace which resides on the Veritas Filesystem (VxFS), 
the "df -k" OS command still shows disk space not release back 
to the OS. 
 
However, both the "ls -l" and "db2 list tablespace" commands 
show the DMS container size has been reduced. NOTE: the issue 
is only applicable to the Veritas filesystem (VxFS).
Problem Summary:
Problem will be addressed future release such as V9.5 and 
higher.
Local Fix:
External Veritas setext tool can be used to release the space 
but should be done with caution, and users are advise to take 
a DB2 backup before making any changes.
