Hi Paul, Paul Howarth schrieb: > Can you try: > # vgreduce -v VolGroup00 /dev/hdb1 That did the trick. This is the first time I'm working with LVM, but meanwhile I love it. I moved everything and finally have the following configuration: # df -h Dateisystem Größe Benut Verf Ben% Eingehängt auf /dev/mapper/VolGroup00-LogVol00 37G 4,4G 31G 13% / /dev/hda1 99M 16M 79M 17% /boot none 252M 0 252M 0% /dev/shm /dev/hdb1 99M 16M 79M 17% /mnt/boot.new # vgdisplay -v Finding all volume groups Finding volume group "VolGroup00" --- Volume group --- VG Name VolGroup00 System ID Format lvm2 Metadata Areas 1 Metadata Sequence No 15 VG Access read/write VG Status resizable MAX LV 0 Cur LV 2 Open LV 2 Max PV 0 Cur PV 1 Act PV 1 VG Size 38,22 GB PE Size 32,00 MB Total PE 1223 Alloc PE / Size 1223 / 38,22 GB Free PE / Size 0 / 0 VG UUID Scg1fw-WM5q-eoj5-rcf8-AAAi-sKmV-nrWAYK --- Logical volume --- LV Name /dev/VolGroup00/LogVol00 VG Name VolGroup00 LV UUID c3JfzP-cN3w-v49v-nXYN-whIc-b5A2-f7KMzx LV Write Access read/write LV Status available # open 1 LV Size 37,22 GB Current LE 1191 Segments 2 Allocation inherit Read ahead sectors 0 Block device 253:1 --- Logical volume --- LV Name /dev/VolGroup00/LogVol01 VG Name VolGroup00 LV UUID K6Tqyu-jO0S-BpPC-8ob7-t7Qd-SOQ1-aK6EUY LV Write Access read/write LV Status available # open 1 LV Size 1,00 GB Current LE 32 Segments 1 Allocation inherit Read ahead sectors 0 Block device 253:2 --- Physical volumes --- PV Name /dev/hdb2 PV UUID gaBRx9-fZQ4-0u5P-8kv4-2mp8-xiua-K7hNYQ PV Status allocatable Total PE / Free PE 1223 / 0 The last thing before I can boot from my drive is to copy the MBR. # grub-install /dev/hdb /dev/hdb does not have any corresponding BIOS drive. What does that mean? Finally one last question: do you think it's a good idea to use this "old" disk within a RAID 1? It would be a nice exercise for me anyway. :-) Regards, Oliver
