I'm seeing this error during reinstallation of a host using LVM.
It seems that the LVM output defaults to using 'human-readable' as unit size,
which according to the man page of pvs may use '<' as rounding indicator.
Setting LVM to use a fixed unit for formatting, seems to fix the problem:
Linux::LVM->units('b');
Output of Linux::LVM and the other commands without specifying units.
