Now i want to be LogVols in VolGroup to be contiguous physically, such that logical Volume 0 remains on 0 to 191 PEs and logical volume 1 should start from PE 192 and finishes at PE 223. I figured it out that for this shuffling of PEs the command should be, # pvmove -v /dev/hda6:233-264 /dev/hda6:192-223 which gives following error Finding volume group "VolGroup00" No extents available for allocation or # pvmove -v -n /dev/Volgroup00/logVol01 /dev/hda6 /dev/hda6:192-223 which gives following error Named LV and old PV must be in the same VG pvmove: Move extents from one physical volume to another in both cases i cant figure out what is the problem as there are PEs available and also LV and the "old PV" infact are in same VG. I have also tried the simple command # pvmove -v -n /dev/Volgroup00/logVol01 which does not give any error, but do nothing as the mapping remains same. anybody here to help me out? -ajeet.
