Creating
ext3
mkfs.ext3 /dev/sdb1 -L my_external
You might want to enable additional features using tune2fs.
tune2fs -O +feature /dev/sdb1
feature may be one of the following:
| feature | Description |
|---|---|
large_file |
If you have files > 2GiB, this flag should be automatically set by the kernel. |
dir_index |
Uses hashed b-trees to speed up lookups in large directories. |
sparse_super |
Limits the number of backup superblocks to save space on large filesystems. |
There are some more, but these are the most interesting. On external drives you might want to set the reserved space for the root-user to 0% instead of the default 5%:
tune2fs -m 0 /dev/sdb1
You can show all information about the superblock using:
tune2fs -l /dev/sdb1
Renaming
To rename a partition (e.g. an USB drive), there are different tools for different filesystems. There's a nice overview at ubuntu.com.
ext2 / ext3
You need the package e2fsprogs.
sudo e2label /dev/sdb1
sudo e2label /dev/sdb1 my_external
FAT16 / FAT32
You need the package mtools.
sudo mlabel -i /dev/sdb1 -s ::
sudo mlabel -i /dev/sdb1 ::my_external
JFS
You need the package jfsutils.
sudo jfs_tune /dev/sdb1
sudo jfs_tune -L my_external /dev/sdb1
NTFS
You need the package ntfsprogs.
sudo ntfslabel /dev/sdb1
sudo ntfslabel /dev/sdb1 my_external
ReiserFS (v3)
You need the package reiserfsprogs.
sudo reiserfstune -l my_external /dev/sdb1
XFS
You need the package xfsprogs.
xfs_admin -l /dev/sdb1
xfs_admin -l my_external /dev/sdb1
