GEOMMAN — GEOM Manager

geomman is a text-based disk management tool for FreeBSD, built on top of bsddialog(3).
It provides a simple TUI for working with partitions, filesystems, and GEOM labels.

Running geomman requires root privileges to make low-level changes to disks:

sudo geomman

Main Features

When started, geomman shows a menu with common disk operations:

• Copy – Select a target partition.
• Paste – Write the copied partition into available disk space.
• Move – Change the position of a partition (feature planned, not yet implemented).
• Create – Make a new partition, choose a filesystem (UFS, EXT, exFAT, FAT, NTFS), and optionally set a label using glabel (GEOM).
• Delete – Remove an existing partition.
• Check – Run a filesystem integrity check and try to repair issues.
• Finish – Review and either apply or discard all pending changes.

Extra Requirements

Some filesystems need additional tools from the FreeBSD Ports Collection or packages:

• e2fsprogs – ext2, ext3, and ext4
• exfat-utils – exFAT
• ntfs – NTFS

Without these, you won't be able to create a file system of the given type.

Notes

• Partition labels are handled using glabel(8).
• Copy/paste uses the dd(1) utility under the hood.
• The Move function is not implemented yet.

Related Tools

• sade(8) – the original FreeBSD text-based disk editor
• bsddialog(3) – library used for the interface

Development

geomman is inspired by sade(8) but adds plans for broader filesystem support, and ZFS management.
