然后再用命令 pvcreate /dev/sdb1pvcreate /dev/sdb2 转换成物理卷

然后创建逻辑卷lvcreate 创建一个叫xixi 的逻辑卷 （在haha 里）

给逻辑卷加容量
用lvextend –L +大小 /dev/卷组名/逻辑卷名字
然后用 resize2fs /dev/haha /xixi 从新指定一下。

给逻辑卷减容量
先卸载umount 然后用e2fsck –f /dev/haha/xixi 扫描下文件
然后用resize2fs /dev/haha /xixi (150M)--这个容量是减后的大小是多大
然后lvreduce –L -200M /dev/haha/xixi然后从新挂

给组扩充的话。
Vgextend /dev/haha/dev/sdb3 (这个sdb3是一个物理卷把他加到haha这个卷组里)
减的话是
Vgreduce /dev/haha/dev/sdb3
删除逻辑卷的话是
先卸载。然后lvremore /dev/haha/xixi
Vgremore /dev/haha
Pvremore/dev/sdb1
/dev/sdb2
/dev/sdb3
做配额的话。不用UUID挂。
/dev/haha/xixi /挂载点 ext3 defaults0 0
