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：
@H_403_2@cuttle:~# fdisk -l /dev/vda
Disk /dev/vda: 21.5 GB,21474836480 bytes
255 heads,63 sectors/track,2610 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00027dbb
Device Boot Start End Blocks Id System
/dev/vda1 * 1 31 248976 83 Linux
/dev/vda2 32 2610 20715817+ 8e Linux LVM
其中说vda2约为20gig
@H_403_2@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所以目前的pv约为4-5演出
@H_403_2@cuttle:~# pvresize -v /dev/vda2 Using physical volume(s) on command line Archiving volume group "debian" Metadata (seqno 12). No change to size of physical volume /dev/vda2. Resizing volume "/dev/vda2" to 9975981 sectors. Updating physical volume "/dev/vda2" Creating volume group backup "/etc/lvm/backup/debian" (seqno 13). Physical volume "/dev/vda2" changed 1 physical volume(s) resized / 0 physical volume(s) not resizedpvresize说“物理卷大小/ dev / vda2没有变化”
@H_403_2@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
man partprobe
