Maybe I didn't make the problem clear in my first posting. I created a single member md RAID1 device /dev/md2 on top of /dev/sda3 (single member because the other disk /dev/sdb3 was holding the data). Then I created a PV on /dev/sda3 and a VG on it. I should have done this on /dev/md2, though. Small oversight on my part. (I had to recreate that array after a complete lowlevel format of the disk and I had the data all fine on /dev/sdb3. So I accidentally created the PV on the "counterpart" /dev/sda3 instead of the existing raid device.) Then I moved all the LVs and data back on that PV, added /dev/sdb3 to the md device and let it sync. And now I have two identical PVs on both disks instead of one PV on the md device. So, you think pvmove /dev/sda3 /dev/md2 would just do what I want? Should I break the array and perform the move on the single member array, so that I can keep my data on /dev/sdb3 in case something goes wrong?
