HP-UX邏輯卷管理

1、建立物理卷
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、建立卷組：
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、劃分邏輯卷：
zdcxdb[/]#lvcreate -L 10240 -n lvywlog /dev/vg01
zdcxdb[/]#newfs -F vxfs /dev/vg01/rlvywlog

4、掛載邏輯卷：
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.

/dev/vg01/lvbackup /backup vxfs delaylog 0 2
zdcxdb[/]#mount -a

另：
擴充套件邏輯卷：
zdcxdb[/]#umount /ywlog
zdcxdb[/]#lvextend -L 51200 /dev/vg01/lvywlog
zdcxdb[/]#extendfs -F vxfs /dev/vg01/lvywlog
zdcxdb[/]#mount /ywlog
刪除邏輯卷：
zdcxdb[/]#umount /ywlog
zdcxdb[/]#lvremove /dev/vg01/lvywlog
刪除卷組：
zdcxdb[/]#lvremove /dev/vg01/lvbea
zdcxdb[/]#vgreduce /dev/vg01 /dev/disk/disk4
zdcxdb[/]#vgremove /dev/vg01
