Insufficient Free Space to backup APM
Status: ERROR
Additional Notes: ERROR - Please ensure that there is an additional free space of at least 8.27 GB

but I after increase the USER_INSTALL_DIR filesystem have 14 gb free>
/dev/mapper/system_vg-opt_introscope_lv 20961280 6315516 14645764 31% /opt/introscope

but the installer shows the same problem.

Cause

There is a special case where the EM was installed on a mount point and DB was installed on a mount point created in a directory within, Eg:

EM is in /opt/EM (mount point is on /opt)
DB was in /opt/APM/DB (mount point is /opt/APM/DB)

In this case, the DB space should be calculated based on space available in /opt/APM/DB but the installer takes the root /opt and calculates required space based on that for the DB as well.
This issue will be fixed in future releases so the workaround is to increase space in /opt.




 

Environment

APM 10.7

Resolution

Resize /opt so you can proceed with the installation.
