Hello,
I have vol0 on netapp F760 (5.3.5) with mixed 18G and 36G disks. I
noticed,
that there're two disks 36G in the disk group with 18G disks. As I
understand,
I lose 2x(36-18)=36G of the disk space.
You should double-check your disk totals to see if this is true.
You only lose space if those 36GB disks were using to reconstructed failed 18GB disks. If they were added normally, what happened should be that one 36GB disk is now the parity drive and the other 36GB disk is fully used. There's no "lost space" other than the parity drive.
You will find this all explained in your sysadmin guide.
Now I added two new 18GB disks to the netapp. My question is how I can replace the 36G disks with the new ones.
If the disks are fully used, you can't replace them with 18GB disks. If they are partially used, you can, but you'll need two more 18GB disks (ones you haven't added yet) and replace them one at a time, through a potentially dangerous raid fail operation. But don't do this until you read the manual and determine the real status of those 36GB drives.
