Reason to use a partition

[Ramon Hofer <ramonhofer@bluewin.ch>]

Hi all

I have accidentally found that it's possible to use a whole disk instead 
of a partition spanning a whole disk.

I have two 2 TB disks. One (sdi) has a partition with jfs and the other 
(sdk) has xfs directly on the disk:

/dev/sdi1      jfs    1.9T  1.9T  3.9G 100% /mnt/recordings
/dev/sdk       xfs    1.9T  1.9T  3.3G 100% /mnt/recordings_temp

Is there a reason why one should use a partition spanning the whole disk 
instead of creating the filesystem directly on the disk?


Best regards
Ramon
