Hi all, I am working on a project to evaluate LVM2 against Veritas Volume Manager for a new Linux deployment. I am trying to get a Raid 0+1 solution working and I'm struggling. So far, this is where I am: 1. I created 8GB partitions on 4 disks, sdb, sdc, sdd and sde, and set their partition types to 8e with fdisk 2. I then ran vgscan, follwed by pvcreate /dev/sdb1, /dev/sdc1, /dev/sdd1, /dev/sde1 3. Next, I created 2 volume groups as follows: vgcreate StripedData1 /dev/sdb1 /dev/sdc1 vgcreate StripedData2 /dev/sdd1 /dev/sde1 4. Next, I created 2 volumes, one in each group as follows: lvcreate -i 2 -I 64 -n Data1 -L 6G StripedData1 lvcreate -i 2 -I 64 -n Data2 -L 6G StripedData2 Now I have 2 striped volumes, but no redundancy. This is where I think things start to go wrong. 5. I now create a raid device, /dev/md0 consisting of these two volumes. I run mkraid on this, create a file system, and mount it on /Data1. This all works fine, and I have a 6GB filesystem on /Data1 Now I need to be able to resize this whole solution, and I'm not sure if the way I've built it caters for what I need to do... I unmount /Data1 and use lvextend to extend the 2 volumes from 6GB to 7.5GB. This succeeds. Now even though both of the volumes that make up /dev/md0 are extended, I cannot resize /dev/md0 using resize2fs /dev/md0 Can anyone advise me how I can achieve what I'm looking for here ? I'm guessing maybe I did things the wrong way around, but I can't find a solution that will give me both striping and mirroring :( Thanks in advance, -- Wayne Pascoe _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
