Ah. Ok. But to be honest I could have (and indeed should have) deleted the sanpshot= =20 before doing the write to the volume which caused the snapshot ot=20 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. > You should upgrade to the latest LVM 1.0.8 kernel code.

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 ? TTFN --=20 Roger. Home| http://www.sandman.uklinux.net/ Master of Peng Shui.
