Sorry, let me explain.
We are using Oracle. Oracle uses filesystems to create datafiles in, for example it will create files like:
/oradata01/system01.dbf /oradata02/users01.dbf
Now if /oradata02 (a new filesystem I created) points to the device /dev/sda, instead of /dev/sda1 (a partition on sda), will this be a problem ? As far as I know, which isn't that much, there should be no problem.
There isn't. Reiserfs, ext2/3 and XFS all support file systems that use the entire device, not just a partition. While I haven't tried it, JFS may also support it as well.
They don't specifically support it...they just don't do any sanity checking to make sure that you're NOT attempting to use the measly 1 or 2 blocks reserved for the partition table as part of your filesystem. Other than checking the name specifically, there's no way for the application to distinguish the difference between an entire disk and a partition (they're both block devices). In fact, I've even made ext2/3 and reiserfs filesystems WITHIN A REGULAR FILE out in /tmp.
