lvm extended

In lvm some fs are marked Linux LVM but what is extended? that slice of the disk marked as extended appears to be used but does not appear in pvscan - the only thing showing in pvscan is the lvm partition. just dont understand what the extended space is for. I thought it could be added to a vg but seems to be used up .

Sorry I didn't mean to say fs - does that mean that is free to add to the volume group once it has been brought under volume manager control?

No, extended partition is created as second, third or forth partition to allow partition number go beyond 5.
So the actual partition is /dev/sda5, /dev/sda6... which are within /dev/sda4 (extended).
You can see the start sector of /dev/sda5 are the same as /dev/sda4 (in my example, 9775).
