Hi all, I have discovered a bug with LVM 1.0.8 on the 2.4.31 kernel, where the PEs are not aligned on the extent boundary, which results in the last PE in a PV to be less than the configured extent size. But the kernel LVM code assumes all extents are the _same_ length, so when it tries to map a logical sector to a physical sector for a 'partial PE', the physical sector calculated will be wrong and can corrupt data.
