1、创建物理卷
zdcxdb[/]#ll /dev/rdisk
total 0
crw-r----- 1 bin sys 12 0x00000c Apr 11 18:20 disk33
crw-r----- 1 bin sys 12 0x00000d Apr 12 16:26 disk34
crw-r----- 1 bin sys 12 0x00000e Apr 11 18:20 disk35
crw-r----- 1 bin sys 12 0x000025 Apr 27 09:43 disk50
zdcxdb[/]#pvcreate -f /dev/rdisk/disk50
Physical volume "/dev/rdisk/disk50" has been successfully created.
2、创建卷组:
zdcxdb[/]#mkdir /dev/vg01
zdcxdb[/]#mknod /dev/vg01/group c 64 0x010000
zdcxdb[/]#vgcreate /dev/vg01 /dev/disk/disk50
Warning: Max_PE_per_PV for the volume group (65535) too small for this PV (153599).
Using only 65535 PEs from this physical volume.
Increased the number of physical extents per physical volume to 65535.
vgcreate: Volume group "/dev/vg01" could not be created:
VGRA for the disk is too big for the specified parameters. Increase the
extent size or decrease max_PVs/max_LVs and try again.
zdcxdb[/]#vgcreate -s 32 /dev/vg01 /dev/disk/disk50
Increased the number of physical extents per physical volume to 19199.
Volume group "/dev/vg01" has been successfully created.
Volume Group configuration for /dev/vg01 has been saved in /etc/lvmconf/vg01.conf
3、划分逻辑卷:
zdcxdb[/]#lvcreate -L 10240 -n lvywlog /dev/vg01
zdcxdb[/]#newfs -F vxfs /dev/vg01/rlvywlog
4、挂载逻辑卷:
zdcxdb[/]#mkdir ywlog
zdcxdb[/]#vi /etc/fstab
zdcxdb[/]#cat /etc/fstab
# System /etc/fstab file. Static information about the file systems
# See fstab(4) and sam(1M) for further details on configuring devices.

另:
扩展逻辑卷:
zdcxdb[/]#umount /ywlog
zdcxdb[/]#lvextend -L 51200 /dev/vg01/lvywlog
zdcxdb[/]#extendfs -F vxfs /dev/vg01/lvywlog
zdcxdb[/]#mount /ywlog
删除逻辑卷:
zdcxdb[/]#umount /ywlog
zdcxdb[/]#lvremove /dev/vg01/lvywlog
删除卷组:
zdcxdb[/]#lvremove /dev/vg01/lvbea
zdcxdb[/]#vgreduce /dev/vg01 /dev/disk/disk4
zdcxdb[/]#vgremove /dev/vg01
