pvmove

Move data between physical volumes

$ pvmove [/dev/sda1] [/dev/sdb1]

$ pvmove [/dev/sda1]

$ pvmove -v [/dev/sda1]

$ pvmove --abort

pvmove [options] source [dest]

pvmove migrates data between LVM physical volumes while the logical volumes remain online and accessible. This enables live storage migration, allowing administrators to replace disks, rebalance storage, or evacuate a physical volume before removing it from a volume group.
When called with a source and destination physical volume, pvmove relocates all physical extents from the source to the destination. If no destination is specified, LVM automatically distributes the data across available physical volumes in the same volume group. The -n flag restricts the move to a specific logical volume. Operations can be run in the background with -b and aborted with --abort if needed.

SOURCE

Source physical volume.

Destination physical volume.

Verbose output.

Abort in-progress move.

Background mode.

Move only this LV.

Requires LVM. Can be slow for large volumes. Interruptible.

pvmove is part of LVM2 for physical volume data migration.
