Both Xen and KVM support online resize of the virtual block devices that the virtual machines use. Unfortunately, since the partitions in the boot virtual block device are already in use, those can't be modified online and the virtual machine won't pick up the changes on the boot virtual block device without a reboot. We are looking for the ability to dynamically increase a partitioned volume ...The output types that have a partitioned disk will have a single partition and additionally any platform-specific partitions that are required to boot the system image. For example, qcow2 image type has a single root partition, and possibly a platform specific boot partition - like PReP for PPC64 system - that the image requires to boot.[解決方法が見つかりました!] VMを停止します 実行qemu-img resize vmdisk.img +10Gして画像サイズを10Gb増やします VMを起動し、通常はその中のパーティションとLVM構造のサイズを変更します News and feature lists of Linux and BSD distributions.

Ceph理论. 注意点: a, 一个ceph cluster至少需要1个mon节点和2个osd节点才能达到active + clean状态(故osd pool default size得>=2, 注意:如果不想复制的话,弄一个osd节点也是可以的,只需要将复制的备份数由默认3改为1即可,即sudo ceph osd pool set data min_size 1),meta节点只有运行ceph文件系统时才需要。 An image format like qcow2 has the largest overhead compared to raw images when it needs grow the image, i.e. allocate new clusters. One scenario where you constantly get this worst case is the installation of an OS to an empty qcow2 image. Therefore installations are a good test to see if we get reasonable performance in this case. qcow2 เป็นรูปแบบสตอเรจค่าเริ่มต้น, cache = none (raw ก่อนหน้านี้) KVM64 เป็นประเภทของซีพียูเริ่มต้น (ก่อนหน้านี้ qemu64) e1000 เป็นค่าเริ่มต้น NIC (previous rtl8139) Get Social!qcow2 is a virtual disk image format developed by the guys who created QEMU and is one of the most versatile virtual disk formats available.
