Suji's blog: How to add a disk to LVM

Suji's blog: How to add a disk to LVM:


Quick Notes First:

Formatting the new Disk

Suppose the Disk is /dev/sdb, the second scsi disk,
   fdisk /dev/sdb
   create as many partitions as you need using command n
   Label them with command t as 8e for making it Linux LVM
   Write and Exit with the command w.
Format the partitions you require using mkfs command
   mkfs -t ext3 -c /dev/sdb1
LVM commands
   pvcreate /dev/sdb1
   vgextend VolGroup00 /dev/sdb1
   lvextend -L 15G /dev/VolGroup00/LogVol01 ;for extending LogVol to 15GB
   lvextend -L+1G /dev/VolGroup00/LogVol01 ;for adding one more GB to Logical Volume LogVol01
   ext2online /dev/VolGroup00/LogVol01 ;for resizing the Logical Volumes
Thats it finished

On Ubuntu Intrepid 8.10 you need to use resize2fs to resize the lvm.
