The below email is classified: Internal Hello group,
Recently we had a DASD failure and I had to delete and recreate logical volume in LVM. We had two model-9 DASDs defined as two logical volumes (different volume groups). I used lvcreate -l 1760 to make sure the number of extents is the same as before. When I mount it, df command shows 110MB difference from old volume. In LVM number of Allocated PE are the same. Volume db4lv was created by LVM2 version 2.02.39 back in 2014... Volume db1lv created by LVM2 version 2.02.98(2). They have to match in size. Any ideas what can be the reason of this ?
