bdf o/p is not reflecting properly

Hello Guruz,

Note:- Points with be given without any fail

After long time…

Mountpoint is 100%, but actual utilization very very low. ( I faced this issue many times, once I unmount and mount the FS it will be resolved )

I check inode is also 0% utilized.

1) Why it’s reflecting 100% used, though the actual utilization very very low
2) Is there any way we can sort it out online without unmounting it?

"actual utilization very very low"

how are you determining "actual utilization"?

Hi:

I assume that you are comparing 'bdf' and 'du' output. The discrepancies usually arise from temporary, open files (that will be removed when the last process using them terminates).

You could use 'lsof' to look for open files with a link-count of zero. These are files holding space that will be returned once the owning process terminates.

Regards!
