导读:我增加了我用作LVM PV的分区大小,但运行pvresize似乎没有看到额外的空间: cuttle:~# fdisk -l /dev/vdaDisk /dev/vda: 21.5 GB,21474836480 bytes255 heads,63 sectors/track,2610 cylindersUnits = cylinders of 16065 * 512 = 8225280 bytesSector size (

Physical volume "/dev/vda2" changed 1 physical volume(s) resized / 0 physical volume(s) not resized pvresize说“物理卷大小/ dev / vda2没有变化” cuttle:~# pvdisplay --- Physical volume --- PV Name /dev/vda2 VG Name debian PV Size 4.76 GiB / not usable 3.08 MiB Allocatable yes (but full) PE Size 4.00 MiB Total PE 1217 Free PE 0 Allocated PE 1217 PV UUID tehZic-5vfN-rsrm-B8lN-lpgc-yQT1-ioH1V0 并且光伏的大小没有改变. 不知道我还可以做些什么来使用额外的空间.我想我可以将分区大小调整为pv的大小,然后添加第二个分区,但在我看来,我在这里尝试做的事情应该可行. 解决方法
partprobe / dev / vda
