Hello, I'm trying to migrate my existing KVM images to Proxmox KVM virtual machine. I have to do that for my existing LXC containers. The storage i prefer to use is LVM thin pool, because this storage support live snapshot of all types of VM's - KVM or LXC based. For the migration purpose i'm follow these steps: 1. I create new VM to the LVM thin pool - this creates new logical volume for me. 2. I use dd command to copy the data from my existing VM image to the newly created lvm volume. The problem is very strange because i have success with first vm, but when i try to another i got the I/O error. See some technical info here: http://pastebin.com/wxLyk6iE So when i'm in this situation i have to reboot the server, then use lvconvert --repair Root-VG/lvmthin, then use lvchange -a y Root-VG/lvmthin, and the logical volumes on the pool is also corrupted - data or metadata column is shown as 0. I have to use dd again to import the data's to the volumes. Can somebody help me with this?
