I don't think I do: # pvdisplay /dev/sda --- Physical volume --- PV Name /dev/sda VG Name datavol PV Size 931.51 GB / not usable 1.71 MB Allocatable yes=20 PE Size (KByte) 4096 Total PE 238467 Free PE 85356 Allocated PE 153111 PV UUID C22uVB-4m26-5cvl-I11V-NXCm-mVNo-UTAXUH But of course, I just want to get the opinion of the experts. > I don't think you need something to repair the PV.
