REPARTITION(8) System Manager's Manual REPARTITION(8)NAME
repartition - load a partition table
repartition device [partition-file]
Repartition uploads a new partition table for the partitions of device. The table is obtained from the first sector of partition-file if
given, device otherwise. Device may refer to the whole drive or a primary partition, depending on whether you want to upload a partition
or a subpartition table. The partitions will be truncated to fit within the enclosing device like the disk driver does, unless the numbers
are coming from partition-file.
repartition /dev/hd4 /etc/hd4.table
Reload the partition table of drive 0 setting /dev/hd[1-4], and the subpartition table of /dev/hd4 setting /dev/hd4[a-d] using a file. The
latter may be useful if you need more than the 4 subpartitions a single Minix partition gives you.
The new table is printed on standard output.
SEE ALSO hd(4), part(8).
The disk must be in use for the changes to stick. The partition table of an idle disk will be reloaded on the first open.
