磁盘管理

查看磁盘信息

# 查看物理卷\npvs\n\n# 查看卷组\nvgs\n\n# 查看块设备\nlsblk\n

添加 LVM 存储

# 扫描可用 LVM\npvesm scan lvm\n\n# 添加目录存储\npvesm add dir data --path /data\n

创建逻辑卷

# 创建 140G 大小的逻辑卷\nlvcreate -L 140G -n data debian-vg\n\n# 格式化为 ext4\nmkfs.ext4 /dev/mapper/debian--vg-data\n\n# 挂载\nmount /dev/mapper/debian--vg-data /data\n

删除逻辑卷

# 先卸载\numount /dev/data/lv-ceph\n\n# 删除逻辑卷\nlvremove /dev/data/lv-ceph\n

缩减逻辑卷

注意：缩减操作有数据丢失风险，请先备份重要数据。

# 卸载分区\numount /home\n\n# 检查文件系统\ne2fsck -f /dev/mapper/debian--vg-home\n\n# 先缩减文件系统到目标大小\nresize2fs /dev/mapper/debian--vg-home 100G\n\n# 再缩减逻辑卷\nlvreduce -L 100G /dev/mapper/debian--vg-home\n\n# 重新挂载\nmount /dev/mapper/debian--vg-home /home\n

扩展逻辑卷

# 扩展逻辑卷到最大可用空间\nlvextend -l +100%FREE /dev/data/lv-data\n\n# 扩展文件系统（自动调整到卷大小）\nresize2fs /dev/data/lv-data\n

注意事项

缩减逻辑卷前必须先缩减文件系统，否则会损坏数据
resize2fs 对 ext4 文件系统有效，其他文件系统使用对应工具
PVE 存储配置文件位于 /etc/pve/storage.cfg
