Netapp Volume Not Showing correct used size.....

Hi dear

I have FAS2240-2 , i have created two Volumes of 1 TB for my netbackup DSU's , and mapped them using iscsi into my backup server... and configure DSU01 and DSU02 for them.

Now on netapp its shows its 98% full and other one is 90% full, but when i log on to backup server and check the mapped drive status, its shows different and it is quite 70% full.

Dont know whats the issue is.

Kindly guide me what to do.

Regards

M.Amir

Re: Netapp Volume Not Showing correct used size.....

Pls share df -s & df -h of the volume

Hi Amir,

I believe you have created the Thick LUN. Means you LUN is physically allocated the space. That's why form you storage level (volume) show 98% and 90% full.

What is the occupied size shown in lun show -v output ?

I believe Fractional reserve is been used for the residue space ,vol options will clear the doubt
