Hello, I have problem with my xen installation on my wheezy server. I haven''t really an idea hown to. So I''m using xen image files. Now one VPS reached the limit of free space and killed more or less itself. I needet some hours to find out. Now my Idea to solve is to migrate the files in an lvm version. I never used it before, but I have no problem to configure. Now I ask how to migrate the files and how to install it in a lvm partition. Anyone here who could help? Regards Thore

Free advice: always backup your image before doing anything to it. :-) Wei.> Regards > Thore > > > _______________________________________________ > Xen-users mailing list > Xen-users@lists.xen.org > http://lists.xen.org/xen-users

Step 1 : convert image in "raw" format. qemu-img convert -f vmdk original_image.vmdk -O raw xen_compatible.img VMDK or another format like QCOW, QCOW2 ... Step 2 : create your LVM partition Make it bigger than "xen_compatible.img" ! Step 3 : copy the data "dd" is your friend dd if=xen_compatible.img of=/dev/your_lvm_partition bs=32k Step 4 : resize the FS Mount the partition on another machine (could be another VM) and "resize" the filesystem to "fill" the LVM partition. (It is not possible to do a "live" filesystem resize ). Step 5 : all should be OK link the new filesystem to your VM instead of the "old" image file and try to start your VM The process is safe as your original image is not destroyed, you can wait a little before scratching it. PS: I never use image files, LVM is easier to adapt to the needs.
