linux如何创建卷组？

1． 创建一个物理卷Pvcreate /dev/sd1/dev/sd2 /dev/sd3 /dev/sd42． 用刚才创建的物理卷创建一个卷组Vgcreate 卷组名 /dev/sd1/dev/sd2 /dev/sd3 /dev/sd43． 创建逻辑卷Lvcreate -L(size) -n (name) 卷组名4． 创建文件系统Mkfs.ext3 逻辑卷名(/dev/卷组名/逻辑卷名)创建挂载点mkdir /namemount /dev/卷组名/逻辑卷名 /挂载点pvcreate /dev/emcpowers1 /dev/emcpowerq1 /dev/emcpowerp1/dev/emcpowerr1vgcreate backupvg /dev/emcpowers1 /dev/emcpowerq1/dev/emcpowerp1 /dev/emcpowerr1lvcreate –L 790G –n backuplv backupvgmkfs.ext3 /dev/mapper/backupvg-backuplvmkdir /backupdbmount /dev/mapper/backupvg-backuplv /backupdb
