 From above we can see that the emc-srm file contains the stats information.

We can take the backup of data and store it to the customer's local system and remove it from the /home directory
[root@VNX4145-CS0 nasadmin]# rm -rf emc-srm

after deleting the srm file:
[root@VNX4145-CS0 ~]# df -k
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/hda3              2030768   1291992    633952  68% /
none 1036364 0 1036364 0% /dev/shm
/dev/hda1 264445 16721 236802 7% /boot
/dev/mapper/emc_vg_pri_ide-emc_lv_home
604736 163560    410456  29% /home <---------------------------

Take customer's permission before proceeding on the same.
Customer can either move these files to their local system/computer, or if they don't require the statistic data go ahead with deleting the srm file.
