Need Real Name

Hardware RAID with LVM, the Drives 200 GB where changed up to 400 GB. It is the same device for example /dev/hda but now are for example 200 GB free unsued space. Example from a Test VMWare Maschine: fdisk -l Disk /dev/hda: 5368 MB, 5368709120 bytes 255 heads, 63 sectors/track, 652 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hda1 1 17 136521 82 Linux swap / Solaris /dev/hda2 * 18 24 56227+ 83 Linux /dev/hda3 25 601 4634752+ 8e Linux LVM I know i can create from the unused space (in this example are 51 cylinders) a Partition, an create the from this partition a PV. Disk /dev/hda: 5368 MB, 5368709120 bytes 255 heads, 63 sectors/track, 652 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hda1 1 17 136521 82 Linux swap / Solaris /dev/hda2 * 18 24 56227+ 83 Linux /dev/hda3 25 591 4554427+ 8e Linux LVM /dev/hda4 592 600 72292+ 5 Extended /dev/hda5 592 600 72261 83 Linux pvcreate /dev/hda5 vgextend rootvg /dev/hda5 Volume group "rootvg" successfully extended but if the space is not enough and the drives are changed to bigger drives for example from 400 GB up to 800 GB Drives i now have 400 GB unused space and if i now wann create a partition with this space i can´t create it localhost:~ # fdisk /dev/hda Command (m for help): n No free sectors available Command (m for help): it never mind if i create 4 primary partitions or 3 primary partitions an 1 extened with 1 logical partiton i is the same problem with fdisk how can i to transcribe the resize of the LVM partiton /dev/hda3 in this example ? i tryed to use parted Disk /dev/hda: 5368 MB, 5368709120 bytes 255 heads, 63 sectors/track, 652 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hda1 1 17 136521 82 Linux swap / Solaris /dev/hda2 * 18 24 56227+ 83 Linux /dev/hda3 25 591 4554427+ 8e Linux LVM /dev/hda4 592 600 72292+ 5 Extended /dev/hda5 592 600 72261 83 Linux Disk geometry for /dev/hda: 0kB - 5369MB Disk label type: msdos Number Start End Size Type File system Flags 1 32kB 140MB 140MB primary linux-swap type=82 2 140MB 197MB 58MB primary ext3 boot, type=83 3 197MB 4861MB 4664MB primary lvm, type=8e 4 4861MB 4935MB 74MB extended type=05 5 4861MB 4935MB 74MB logical type=83 Using /dev/hda (parted) resize 4 592 652 Error: Can't have overlapping partitions. (parted) sorry in better english, the same: Situation: LVM using hardware-RAID(200G total) Problem: Howto double the RAID-size (400G total) by disk exchange. I will use the same devicefile e.g. /dev/hda (then with 200 GB freespace) Example 1: VMWware-simulation original Raid (200G): fdisk -l Disk /dev/hda: 5368 MB, 5368709120 bytes 255 heads, 63 sectors/track, 601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hda1 1 17 136521 82 Linux swap / Solaris /dev/hda2 * 18 24 56227+ 83 Linux /dev/hda3 25 601 4634752+ 8e Linux LVM After exchange of one disk: fdisk -l Disk /dev/hda: 5368 MB, 5368709120 bytes 255 heads, 63 sectors/track, 652 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hda1 1 17 136521 82 Linux swap / Solaris /dev/hda2 * 18 24 56227+ 83 Linux /dev/hda3 25 591 4554427+ 8e Linux LVM /dev/hda4 592 601 72292+ 5 Extended /dev/hda5 592 601 72261 83 Linux Now I can create a partition using the new freespace (51 cylinders) pvcreate /dev/hda5 vgextend rootvg /dev/hda5 Volume group "rootvg" successfully extended So, example 1 in the VMWare is fine. Example 2: the real RAID fdisk /dev/hda Command (m for help): n No free sectors available There is no different result either I create 4 primary partitions or 3 primary partitions and 1 extened containing 1 logical partiton. How to resize partiton /dev/hda3 in this example ? You have to remove the extended partition and create a bigger one, the DOS partition table cannot hold more than 4 entries and all "logical" partitions have to fit within the "extended" one, so if there's no slot for a new primary partition and the extended one is full, fdisk gives the above confusing error. |
