I am trying to decrease my /home partition on SLES 10 SP3 using LVM in YAST. I got the error message " please unmount partition before making changes".
I am able to increase the partitions, however when i tried increasing the SWAP partition i got the same error message as above.
Can somebody please help me with how to unmount partitions so i can decrease their size. Also, would the same work for SWAP partition as well without losing data ?

Thanks a lot.
