• AIX LVM in practice: lsvg/lspv/lslv, growing a JFS2 filesystem online, and mirroring rootvg

  AIX's own Logical Volume Manager organizes disks into volume groups, logical volumes and JFS2 filesystems, inspected with lsvg/lspv/lslv rather than Linux's pvs/vgs/lvs. Growing a filesystem online is one chfs command; mirroring rootvg for availability is a four-step sequence (extendvg, mirrorvg, bosboot, bootlist), not just mirrorvg.

• Growing an LVM logical volume and its filesystem online without unmounting

  lvextend -r resizes a logical volume and its filesystem in one step while it stays mounted, calling xfs_growfs or resize2fs as appropriate. XFS filesystems can only ever grow, never shrink; this methodology covers the online-growth path for both.
