EBS expansion of LVM Backed volumes
Raw
EBS expansion of LVM Backed volumes
Procedure:
1. Expand EBS volume
2. Grow Partition - growpart
3. Physical Volume Resize - pvresize
4. Logical Volume Resize - lvresize
5. Resize File System - resize2fs
In this Example we have - 2 Disks, 1 VG, 2 PVs, 3 LVs and EXT4 Filesystem. For XFS use xfs_growfs instead of resize2fs
