It's a bit easier for me to explain it this way: In APFS it's actually a shared partition type of setup (not really the right way to put it). Preserving data on disk3s4 but destroying data on disk3s5, disk3s6,ĭisk3s7 and any invisible free space partitions between those disks ĭisk3s4 will be grown to cover the full space if possible. This example will merge all partitions *BETWEEN* disk3s4 and disk3s7, Ownership of the affected disk is required.Įxample: diskutil mergePartitions JHFS+ NewName disk3s4 disk3s7 Top-to-bottom order given by diskutil list is always the on-disk order. May in certain circumstances not always be in numerical order but the See `diskutil list` for the actual on-disk ordering BSD slice identifiers Merged partitions are required to be ordered sequentially on disk. Should do this if you wish to reformat to a new file system type. However, if 'force' is given, the first partition is always formatted.

Partition is not resizable, you will be prompted if you want to erase. Also, if 'force' is not given, and the first JHFS+), it will be grown in a data-preserving manner, even if a differentįile system is specified (in fact, your file system and volume name parametersĪre both ignored in this case). If 'force' is not given, and the first partition has a resizable file system This given range of two or more partitions will be merged into one.Īll partitions in the range, except for the first one, must be unmountable.Īll data on merged partitions other than the first will be lost data on theįirst partition will be lost as well if the 'force' argument is given. Is the starting partition the second disk parameter is the ending partition Merge two or more pre-existing partitions into one.
