增加 LVM 以使用 virtualbox/debian 上的所有可用空間
我已經為 VirtualBox 複製並調整了磁碟映像的大小，但我找不到使用所有新空間的方法。這就是我開始的方式：
磁碟：
Disk /dev/sda: 80.5 GB, 80530636800 bytes 255 heads, 63 sectors/track, 9790 cylinders, total 157286400 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00034aae Device Boot Start End Blocks Id System /dev/sda1 * 2048 499711 248832 83 Linux /dev/sda2 501758 41940991 20719617 5 Extended /dev/sda5 501760 41940991 20719616 8e Linux LVMlv顯示：
--- Logical volume --- LV Path /dev/localhost/root LV Name root VG Name localhost LV UUID tbJqka-ZlYQ-nkq4-Cufz-Yl7t-peSL-z1FGpR LV Write Access read/write LV Creation host, time localhost, 2014-04-16 21:15:12 +0200 LV Status available # open 1 LV Size 18.91 GiB Current LE 4840 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 254:0 --- Logical volume --- LV Path /dev/localhost/swap_1 LV Name swap_1 VG Name localhost LV UUID 3yEDBL-Nc0G-QuVU-M9iR-Pe3u-r6E4-A5egVb LV Write Access read/write LV Creation host, time localhost, 2014-04-16 21:15:12 +0200 LV Status available # open 2 LV Size 872.00 MiB Current LE 218 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 254:1所以，我現在已經刪除了 sda2 分區並創建了一個新分區，如下所示（這是在重新啟動後）：
Disk /dev/sda: 80.5 GB, 80530636800 bytes 255 heads, 63 sectors/track, 9790 cylinders, total 157286400 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00034aae Device Boot Start End Blocks Id System /dev/sda1 * 2048 499711 248832 83 Linux /dev/sda2 499712 157286399 78393344 5 Extended /dev/sda5 501760 157286399 78392320 8e Linux LVM那麼，我現在應該怎麼做才能增加 LVM 組，然後將大小調整為 100%FREE？
謝謝！
在上述之後，我自己找到了解決方案：
