Thanks very much.
This showed me that my dm-3 was indeed /tmp ,
which is not too bad:
brw-rw---- 1 root disk 253,  3 2007-11-29 22:52 VolGroup00-tmp

I'd noticed a few problems with /tmp ,
eg a file I could not delete:
        [root@alfred tim]# ls -ls /tmp
ls: cannot access /tmp/lvm.log: Input/output error
total 52
...
 ? -????????? ? ?    ?        ?                ? lvm.log
...

I'll try e2fsck-ing it.
