TLDR

$ pvmove -v [/dev/sda1]
Abort move

SYNOPSIS

pvmove [options] source [dest]

DESCRIPTION

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.

PARAMETERS
