Hello, some months ago I setup a redhat box running kernel 2.4.18 and LVM 1.0.3. There were four disks and they we're all included in the LVM-volume I created, which gave me a LVM-volume with a total size of ~230gig. Since this box didn't have more than two IDE-ports, and I already had 4 disks in it, I wasn't planning to expand the volume any further. Therefor I didn't do anything with 256GB limit in spite of a friends recommendations - and now, I just got a IDE controller-card which can take four more devices, and I've already got two disks I would like to include in the LVM-volume. This is my "old" volume (storage): --- Volume group --- VG Name storage VG Access read/write VG Status available/resizable VG # 0 MAX LV 256 Cur LV 1 Open LV 1 MAX LV Size 255.99 GB Max PV 256 Cur PV 5 Act PV 5 VG Size 231.49 GB PE Size 4 MB Total PE 59261 Alloc PE / Size 59261 / 231.49 GB Free PE / Size 0 / 0 VG UUID I99L5r-trcv-x6Hb-1bKC-O5qf-1Mdy-8Q3G8P My devices: pvscan -- ACTIVE PV "/dev/hde" of VG "s0" [74.47 GB / 0 free] (new 80gig - currently setup in a new volume) The 256G limited volume: pvscan -- ACTIVE PV "/dev/hdc1" of VG "storage" [41.92 GB / 0 free] pvscan -- ACTIVE PV "/dev/hdd1" of VG "storage" [42.94 GB / 0 free] pvscan -- ACTIVE PV "/dev/hda5" of VG "storage" [34.86 GB / 0 free] pvscan -- ACTIVE PV "/dev/hdb1" of VG "storage" [53.86 GB / 0 free] pvscan -- ACTIVE PV "/dev/hdb2" of VG "storage" [57.91 GB / 0 free] pvscan -- total: 6 [306.05 GB] / in use: 6 [306.05 GB] / in no VG: 0 [0] (new 80gig included) Well, I've heard you cannot change the MAX LV Size on existing volumes, therefor I created a new volumegroup with the new 80gig disk, called 's0', and a volume called 'vol0'. This time with a 2TB limit: --- Volume group --- VG Name s0 VG Access read/write VG Status available/resizable VG # 1 MAX LV 256 Cur LV 1 Open LV 1 MAX LV Size 2 TB Max PV 256 Cur PV 1 Act PV 1 VG Size 74.47 GB PE Size 32 MB Total PE 2383 Alloc PE / Size 2383 / 74.47 GB Free PE / Size 0 / 0 VG UUID gNo0V0-OOKU-teKS-QenZ-I84O-WkHE-Z7ia5t What I need to do now is to take out one disk at the time from the old volume, and move it to the new one. (root@avalon root)# df -h Filesystem Size Used Avail Use% Mounted on /dev/hda2 2.9G 2.3G 639M 79% / /dev/hda1 30M 4.1M 26M 14% /boot none 125M 0 125M 0% /dev/shm /dev/storage/vol0 228G 164G 64G 72% /storage /dev/s0/vol0 73G 62G 9.7G 87% /voltmp (root@avalon root)# I've moved 62gig from the old volume and over to the new one, so the old volume should have enough space to remove one drive/partition. I've searched the mailinglist archive and checked a couple of howto's, but all I can find information about is how to replace a drive with a new one, not removing one completely. "pvmove" seems to be the answer, but I can't really figure how to do this, and there's no chance I can take backup of 230Gig. How can I move all the content on one of the drives in the volume over to the others and make sure the one I want to remove is empty? Do I need to shrink the volume first, and then use pvmove? I would appreciate if anyone could tell me how to do this, or at least give me some hints.
