我在一台机器上安装了 Proxmox。我需要/dev/mapper/pve-data扩展/dev/sdb5
我怎样才能实现这个目标？

答案1
pvs问题中有趣的信息是、vgs和的输出lvs。
但是，如果我谨慎猜测一下，我会猜想您的VG名为pve，您的lv为data。当前物理卷为/dev/sda5，并且您使用完整分区作为逻辑卷data。我还假设 /dev/sdb5 不包含任何数据，因此我们不会冒丢失任何数据的风险？
我将首先将分区类型/dev/sdb5从更改Linux raid autodetect 为Linux LVM。
您可以使用 fdisk 来执行此操作。
# fdisk /dev/sdb
Command (m for help): t
Partition number (1-5): 5
Hex code (type L to list codes): 8e
Changed system type of partition 5 to 8e (Linux LVM)
Command (m for help): w
然后用来pvcreate创建一个新的物理卷：
# pvcreate /dev/sdb5
现在，输入以下命令时应该会列出 2 个物理卷pvs
# pvs
PV VG Fmt Attr PSize PFree
/dev/sda5 pve lvm2 a-- xx.xxg xx.00m
/dev/sdb5 lvm2 a-- xx.xxg xx.00m
下一步是将新的物理卷添加到卷组中。您可以使用pve扩展卷组来完成此操作。/dev/sdb5vgextend
# vgextend pve /dev/sdb5
如果你现在列出有关卷组的信息，vgs你应该看到你有大小为/dev/sdb5
# vgs
VG #PV #LV #SN Attr VSize VFree
pve 1 1 0 wz--n- xx.xxg xx.00m
要扩展逻辑卷data，请使用命令lvextend。如果您希望使用所有可用的空闲空间，可以这样做：
lvextend -rl +100%FREE pve/data
如果您只希望扩展部分可用空间，可以这样做：
lvextend -rL +50G pve/data
-r 选项会为您调整文件系统的大小，因此您不必随后手动执行此操作。
