AIX

Hellow friends,

We are having AIX 5.3 total memory allotted to /Backup directory is 700GB actual used memory is 250GB ..but when i issue df -gt command to check space it is showing /Backup directory is 70% full ..how to identify root cause.?

I am not fully understanding your message.
Word Memory is normal Reflecting to RAM
File-system is normal using disk space not RAM

Let me check if i can translate it
You have some file-system like /Backup that is having 700GB
When you are checking it with lest say du command ti showing 250GB usage (about 30%) but when you are trying df -g it is saying that file-system in over 70% full.

It is quite often in AIX some file was deleted but application is still locking the inode. (other possible answer - broken file-system). Wait few days if usage does not decrease, stop the application if still no help, unmount file-system and run fsck.
