Ah. Ok.
But to be honest I could have (and indeed should have) deleted the sanpshot 
before doing the write to the volume which caused the snapshot ot 
run out of space. As long as the snapshot intergrity is good I'm happy.

My real worry is taht this was triggered by a raid problem and we've got
serious data corruption in both the ext3 and lvm metadata.

The site seems to be back now.

Ok. We need to make some sort of decision here about what kernel to use
then there has been an degree of discusson about exactly how
conservative we should be anyway . Does 2.4.23 have the vfs-locking
patch ?
