Have you checked attributes (lsattr)? Maybe it's got the immutable flag on.

In any case, the file is for quota definitions though it seems you
don't have quotas activated:

# mount|grep temp
/dev/mapper/vgraid-temprestore on /mnt/temprestore type ext3 (rw)

Check if quotas are really on or off and the attributes.
