GEOMMAN(8) System Manager's Manual GEOMMAN(8) NAME geomman -- interactive GEOM manager DESCRIPTION The geomman utility (TUI) is used for disk administration tasks such as managing partitions, filesystems and labels. It must be run with superuser privileges (for example, via sudo ) to be able to apply changes. Description Copy Select a partition to be pasted. Paste Paste the copied partition into a new available space. Create Create a partition with a filesystem (UFS, exFAT, etc) with specified size and optionally add a mountpoint. The Labels menu allows to add a label via partition scheme (like GPT la- bel) or using glabel(8) from the GEOM framework. The Encrypt menu allows to encrypt the partition using geli(8) from GEOM too. The Options menu shows additional params to create the filesystem. Delete Remove a partition Modify You can change the filesystem type of a partition (removes all old data), or keep the same fileystem and grow or shrink if al- lowed (depends on the filesystem). You may also add a label via partition scheme (e.g. GPT label). Revert Undo any modification or pending operations across all disks/partitions. Check Check and automatically fix the filesystem. Finish All changes are temporary. You may choose to apply them or drop changes. DEPENDENCIES For full functionality, the following packages need to be installed de- pending on the filesystem: exfat-utils Support for exFAT filesystem. You can run pkg install exfat-utils to create and check exFAT filesystems. fuse-ntfs Support for NTFS filesystem. You can run pkg install fusefs-ntfs to create and check NTFS filesystems. Examples To create a partition 1. Select Create over a disk or partition. If you select create over a slice, you'll create a BSD disklabel. 2. Choose a filesystem from the following options: freebsd-ufs, freebsd-swap, ext4, ext3, ext2, fat32, fat16, exfat, ntfs 3. Size of the partition (may append G, M, or K). 4. Select OK , Finish and Commit to apply the change and create the partition To create an encrypted partition 1. Select Create over a disk or partition. 2. Select Encrypt 3. Select an algorithm for the encryption. AES-XTS is selected by de- fault. You can use a passphrase, passfile, passphrase + keyfile or passfile + keyfile. The passphrase works as a password. Passfile works just as passphrase, but contained in a file. Keyfile is a file with random data. You can create one: dd if=/dev/random of=/path/to/keyfile.key bs=64 count=1 Finally, the passfile/key- file path should be in its field. 4. Encryption will be inmediatly applied (without waiting to commit), and the partition will be attached using your configuration. You need to detach the encrypted partition running geli detach /dev/partition when finished using. You should umount the filesys- tem on it first. To create a labeled partition 1. Select Create over a disk or partition. 2. Select Labels 3. Partition Label creates a label using the partition scheme (GPT or APM only). glabel creates a FreeBSD visible-only label using the GEOM framework by adding metadata at the end of the partition. You must use the label only, or may overwrite this metadata. You may label and encrypt a partition too. To copy and paste a partition 1. Select Copy over the partition to be copied (partition, slice, disklabel). 2. Select Paste on the desired disk or slice. 3. You can now choose where to place the partition. To guide youself, there is a start and end number in MiB. Use left/right arrow keys, Next Page, Prev Page to move your partition (in blue). If you need to move faster, change the step value for bigger jumps. To resize a filesystem 1. Select Modify over the partition to be resized. 2. Change the size field. You can grow a UFS, NTFS, ext4, ext3 and ext2 filesystems. And you may shrink a NTFS and ext filesystems only. NOTES • Moving a partition is not implemented yet • To copy and paste a partition, dd(1) is used • Encryption works using geli(8) • Partition labeling either using glabel(8) or the partitioning schemes like GPT labels. SEE ALSO sade(8), bsddialog(3) HISTORY geomman is based on sade(8) and aims to add some filesystems, ZFS, la- bel and encryption features.
