We had a disk fail and replace but forgot to vgreduce first. The drive was on it's own VG and with two empty LV's and these are now causing LVM to complain every time any command is run, i.e.

 # lvscan
  /dev/vg04/swap: read failed after 0 of 4096 at 4294901760: Input/output error
  /dev/vg04/swap: read failed after 0 of 4096 at 4294959104: Input/output error

  /dev/vg04/vz: read failed after 0 of 4096 at 0: Input/output error
  /dev/vg04/vz: read failed after 0 of 4096 at 4096: Input/output error

The two LV's are not important, I just want to stop this error from displaying.
