Proxmox VE 磁盘管理

1、查看硬盘
 Let’s assume we have an empty disk /dev/sda, onto which we want to create a volume group named “vmdata”.
 fdisk -l
 例如有/dev/sda
 2 新建一个分区
 Caution Please note that the following commands will destroy all existing data on /dev/sda.
 First create a partition.
 sgdisk -N 1 /dev/sda
 Create a Physical Volume (PV) without confirmation and 250K metadatasize.
 3 创建pv
 pvcreate --metadatasize 250k -y -ff /dev/sda1
 移除：pvremove /dev/sda1
 4 创建vg
 Create a volume group named “vmdata” on /dev/sda1
 vgcreate vmdata /dev/sda1
 移除：vgremove vmdata
 5 创建lv 薄模式 这里10g根据自己硬盘大小填写
 Creating an extra LV for /var/lib/vz
 This can be easily done by creating a new thin LV.
 lvcreate -L  -T -n  
 #lvcreate -L 10g -T -n iso vmdata
 #lvcreate -L 40g -T -n archlinux vmdata
 创建一个占全部卷组大小的lv，并指定名字为iso
 lvcreate -l 2%VG -T -n iso vmdata
 创建一个空闲空间100%大小的lv，并指定名字为system
 lvcreate -l 100%Free -T -n system vmdata
 移除：lvremove /dev/vmdata/iso
 Now a filesystem must be created on the LV.
 6 警告：
 在某些情况下，LVM不会正确计算元数据池/块大小。请检查metadatapool是否足够大。必须满足的公式是：
 PoolSize / ChunkSize * 64b = MetadataPoolSize
 你可以通过命令获取这些信息
 lvs -a -o name,size,chunk_size
 7 格式化磁盘
 mkfs.ext4 /dev/vmdata/system
 mkfs.ext4 /dev/vmdata/iso
 8 镜像存储需要设置到本地路径
 echo '/dev/vmdata/iso /var/lib/iso ext4 defaults 0 2' >> /etc/fstab
 9 Resizing the thin pool
 Resize the LV and the metadata pool can be achieved with the following command.
 lvresize --size + --poolmetadatasize + /
 Note When extending the data pool, the metadata pool must also be extended.
