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).
