Client has decided they want to increase the number of spares by reducing the root aggregate from 5 to 3 HDD. There is one SVM defined and although there is only a small amount of data on it they would prefer to preserve that if possible.
What is the best way to achieve this? Worse case is trashing the system and rebuild it, but we'd prefer not to if we can avoid it
Is it possible to drop disks out of an aggregate providing there is sufficent remaining capacity to hold the data on the reduced number of disks?
My experience of DataONTAP is very limited so any guidance will be very much appreciated.
Thanks for the swift reply. I'll review the procedure. If I used the two spares to make a new aggregate I guess you can simply add a 3rd disk later after the original root aggregate has been deleted and more drives become available?
Otherwise I would need to delete the data aggregate to release sufficient disks to make a new one. That isn't a major problem as the small amout of data that exists (<1GB) can easily be copied elsewhere.
if you do willing to re-initialize your system (both nodes) and upgrade to 9.2+, you can use ADP. and gain around 4.5TB more then the raid DP>RAID4 conversation (so around 8.5 TB saving in total from what you have now)..
