Hi all, i am working on to expand the volume from NetApp storage and resize it on OS server. What i have done so far was as below:
-Unmount the existing path and delete the old volume group. -Expand the LUN from NetApp controller and mount it into a server. -Create the LVM from new mounted volume. -Resize the volume on OS level.
The problem that i am facing right now is the LUN in NetApp storage is still showing 49% used capacity but it shows 1% used capacity on OS level. I have deleted all the snapshots but it still didnt clear up my used capacity in NetApp storage.
The used capacity in NetApp storage should reduce to 1% following the same used capacity on OS level. (correct me if i'm wrong)
Below are my specs: NetApp controller OS: Data ONTAP 8.2P2 Server OS:RedHat Enterprise Linux 6.2 Using iscsi protocol.
It sounds like you've tried to reuse a LUN instead of creating a new one - the simple answer is that you should have created a new one in this scenario with these aims, but other than space used, there isn't a significant issue.
