The blkid command (part of e2fsprogs) will show you UUID/label/nodename
mappings:

# blkid
/dev/sda1: LABEL="/boot1" UUID="23a710fb-72a3-449f-918e-f8223037caf9"
SEC_TYPE="ext3" TYPE="ext2"
/dev/sda3: TYPE="swap"
/dev/dm-0: UUID="be9ff1e0-2f2e-4d97-91d3-957d1e5249b5" SEC_TYPE="ext3"
TYPE="ext2"
/dev/dm-1: UUID="06c470f1-1b3d-4792-9f0b-5d781e411b51" SEC_TYPE="ext3"
TYPE="ext2"
/dev/dm-2: UUID="9a8d5949-e215-4637-9dec-6cda21f3eb7f" SEC_TYPE="ext3"
TYPE="ext2"
/dev/dm-3: UUID="9678adc4-2aca-4fd4-869b-8a9dc0dbe200" SEC_TYPE="ext3"
TYPE="ext2"
/dev/dm-4: UUID="c880a538-d71b-455e-b661-294eea631e2b" SEC_TYPE="ext3"
TYPE="ext2"
/dev/sdc: UUID="1cbea8b2-115b-4497-aac6-52b83b1129c8" TYPE="ext2"
/dev/dm-8: UUID="8b3e3c44-8396-4bee-a315-c9cba21f5492" SEC_TYPE="ext3"
TYPE="ext2"

Or to search for a UUID:

# blkid -t UUID=be9ff1e0-2f2e-4d97-91d3-957d1e5249b5
/dev/dm-0: UUID="be9ff1e0-2f2e-4d97-91d3-957d1e5249b5" SEC_TYPE="ext3"
TYPE="ext2"

Cheers,
Bryn.
