And a little addition: I created a 3 32GB disks for a KVM-Guest on that SATA-Disk: First on local LVM, second on DRBD using external metadata and third on DRBD using internal metadata. Each of that 32GB disks was partitioned to one 32GB partition and was formatted inside the KVM-Guest (Debian Squeeze, disks connected as virtio-device) with ext3. The formatting took 19s for local lvm, 95s for drbd with external metadata and 133s for drbd with internal metadata... regards Lukas -- -------------------------- software security networks Lukas Gradl <proxmox#ssn.at> Eduard-Bodem-Gasse 6 A - 6020 Innsbruck Tel: +43-512-214040-0 Fax: +43-512-214040-21 -------------------------- _______________________________________________ drbd-user mailing list [email protected] http://lists.linbit.com/mailman/listinfo/drbd-user
