Answer / d.dileep kumar

To Create LVM in RHEL5 the following steps are to be followed
You should create a Partion in the hard disk using /dev/hda
giving LVM id as 8e.Then

step1: pvcreate /dev/hda6
step2: vgcreate /dev/vg0 /dev/hda6 /dev/hda7
step3: lvcreate -l 1000 /dev/vg0 -n lvm0
step4:lvdisplay /dev/vg0/lvm0
step5:mkfs -j /dev/vg0/lvm0
step6:mkdir /database
step7:mount /dev/vg0/lvm0 /database
step8: df -hT

step0: then use "partprobe" cmd
step1: pvcreate /dev/hda10
step2: vgcreate /dev/vg0 /dev/hda10 /dev/hda6
step3: vgchange -ay (to active the volume group)
step4: lvcreate -L 1000M /dev/vg0 -n lvm0
step5: lvdisplay /dev/vg0/lvm0
step6: mke2fs -j /dev/vg0/lvm0
step7: mkdir /database
step8: mount /dev/vg0/lvm0 /database

Answer / yogendra kiran kumar

1) Create 2 LVM partitions using
# fdisk /dev/sda
id for lvm --> 8e

2) # partprobe [ to update kernal ]

3) # pvcreate pv1 /dev/sda{6,7}
[ pv1 is physical volume label and 6,7 are the partition
no's it may differ in ur system ]

4) # pvdisplay
[ to display the physical volume info ]

5) # vgcreate vg1 /dev/sda{6,7}
[ to create logical volume group ]

6) # lvcreate -L 700M -n lv1 vg1
[ to create ur required size partition of lvm ]
[ lv1 is lvm label]

7) # lvdisplay
[ to know about the logical volume ]

8) # mkfs.ext3 /dev/vg1/lv1
[ to give file system ]

9) # mkdir /lv1
# mount /dev/vg1/lv1 /lv1
[ to mount the lv1 to as a seperate disk ]

Answer / karan

First create 2 partition by using
fdisk /dev/hda
and give id =8e
now "w" to write partition and "partprobe" for update the
kernel for new partition

now
#pvcreate /dev/hda{7,8}
#vgcreate vg0 /dev/hda{7,8}
#lvcreate --name HR --size +3000M /dev/vg0

now make a directory named "HR"
#mkdir /HR
#mkfs.ext3 /dev/vg0/HR
now make entry in /etc/fstab, like
# vi /etc/fstab

/dev/vg0/HR /HR ext3 defaults 1 2
now save and exit
and
#mount /dev/vg0/HR /HR
#mount -a
now you can check all by these commands
#pvdisplay
#vgdisplay
you scan also like these command
#pvscan
#vgscan
