blkid -s TYPE

On a C5 box here:
[root@backup670 ~]# blkid -s TYPE
/dev/mapper/vg_backup670-lv_root: TYPE="ext3"
/dev/md1: TYPE="swap"
/dev/md0: TYPE="ext3"
/dev/sdb2: TYPE="swap"
/dev/sdb1: TYPE="ext3"
/dev/sda2: TYPE="swap"
/dev/sda1: TYPE="ext3"
/dev/hda: TYPE="iso9660"
/dev/vg_backup670/lv_root: TYPE="ext3"
/dev/mapper/pachy--mirror-home: TYPE="xfs"
/dev/vg_opt/lv_pachy: TYPE="ext4"
/dev/pachy-mirror/home: TYPE="xfs"
/dev/mapper/vg_opt-lv_pachy: TYPE="ext4"
[root@backup670 ~]#

On a RHEL 6.1 box here:
[root@www ~]# blkid -s TYPE
/dev/sdd1: TYPE="LVM2_member"
/dev/sde1: TYPE="LVM2_member"
/dev/sdk1: TYPE="LVM2_member"
/dev/sdn1: TYPE="xfs"
/dev/sdg1: TYPE="ext4"
/dev/sds1: TYPE="LVM2_member"
/dev/sdy1: TYPE="LVM2_member"
/dev/sdaa1: TYPE="ext4"
/dev/sdag1: TYPE="linux_raid_member"
/dev/sdx1: TYPE="LVM2_member"
/dev/sdaf1: TYPE="linux_raid_member"
/dev/sdad1: TYPE="ext3"
/dev/sdah1: TYPE="ext4"
/dev/sdah2: TYPE="LVM2_member"
/dev/mapper/vg_www-lv_root: TYPE="ext4"
/dev/mapper/vg_www-lv_swap: TYPE="swap"
/dev/md127: TYPE="ext3"
/dev/mapper/vg_bak2-lv_lobak: TYPE="ext4"
[root@www ~]#

Useful stuff.

wow, this is quite a neat trick!

But, it didn't help me much:

[root@HP-DL360 ~]# blkid -s TYPE

/dev/mapper/LVM-swap: TYPE="swap"

/dev/mapper/LVM-root: TYPE="ext3"

/dev/cciss/c0d0p1: TYPE="ext3"

/dev/LVM/root: TYPE="ext3"

/dev/LVM/swap: TYPE="swap"

/dev/mapper/LVM-data: TYPE="ext3"

[root@HP-DL360 ~]# fdisk -l /dev/sda

[root@HP-DL360 ~]#

Which filesystems can this command recognize? I checked the MAN page, but couldn't find a list of filesystems that it's familiar with
