You will need to start by using the command below as root but replace the " # " with the number of the drive you are removing. {{Code|Code=greyhole --going=/var/hda/files/drives/drive<nowiki>#</nowiki>/gh}}
* The command above will check if there are files on the drive you are removing that aren't on other drives, and if so, it will automatically transfer them to other drives. It will then remove that drive from the pool (in greyhiolegreyhole.conf).
Then you will need to start a fsck by using the command below as root, to make sure there are enough file copies on the other drives. {{Code|greyhole --fsck}}
