I am trying to configure LVM based Xen vm migration on ubuntu. But now DRBD is the only good solution i found. can anyone help me to configure DRBD? what is Protocol D in DRBD? What is the need of Remus for DRBD? I am following below links: http://wiki.xen.org/wiki/Install_Xen_4.2.1_with_Remus_and_DRBD_on_Ubuntu_12.10 and same with xen4.1.4 I am getting below error: root@mppdell-Inspiron-3521:/etc/drbd.d# drbdadm create-md drbd-vm md_offset 26843541504 al_offset 26843508736 bm_offset 26842689536 Found ext3 filesystem 26214400 kB data area apparently used 26213564 kB left usable by current configuration Device size would be truncated, which would corrupt data and result in 'access beyond end of device' errors. You need to either * use external meta data (recommended) * shrink that filesystem first * zero out the device (destroy the filesystem) Operation refused. Command 'drbdmeta 1 v08 /dev/vg00/lv01 internal create-md' terminated with exit code 40 one more thing i want to ask: what is the difference between DRBD and NFS for live migration? why LVM doen't support NFS? _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users
