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](https://help.ubuntu.com/community/RenameUSBDrive).
ext2 / ext3
-----------
You need the package [e2fsprogs](apt://e2fsprogs).
sudo e2label /dev/sdb1
sudo e2label /dev/sdb1 my_external
FAT16 / FAT32
-------------
You need the package [mtools](apt://mtools).
sudo mlabel -i /dev/sdb1 -s ::
sudo mlabel -i /dev/sdb1 ::my_external
JFS
---
You need the package [jfsutils](apt://jfsutils).
sudo jfs_tune /dev/sdb1
sudo jfs_tune -L my_external /dev/sdb1
NTFS
----
You need the package [ntfsprogs](apt://ntfsprogs).
sudo ntfslabel /dev/sdb1
sudo ntfslabel /dev/sdb1 my_external
ReiserFS (v3)
-------------
You need the package [reiserfsprogs](apt://reiserfsprogs).
sudo reiserfstune -l my_external /dev/sdb1
XFS
---
You need the package [xfsprogs](apt://xfsprogs).
xfs_admin -l /dev/sdb1
xfs_admin -l my_external /dev/sdb1
