I am trying to reduce the size of a logical volume, but lvreduce keeps giving me errors.  I have rebooted to single-user mode, but am told that data will be lost.  What is the proper procedure for reducing the size of a logical volume in HPUX 10.20?

The LVM has no way to know which extents it manages contain useful data. Thus, if you reduce the size of the LV you could be removing extents which are actually part of the filesystem that was created on the LV. If you have no useful data on the LV, go ahead and change the size and then create a new filesystem. If you do have useful data, back up the filesystem, change the size of the LV, create a new filesystem, and restore the backed up data.
