Join Scott Simpson for an in-depth discussion in this video Migrating and replace a physical volume, part of Linux Foundation Cert Prep: Storage Management (Ubuntu).
- [Instructor] Once we have a volume group…with physical volumes in it,…we can retire a disk and move it's data to a new one.…To do that, we need to add a new drive…and create a partition and a physical volume on it.…We know how to do these things already.…Then, we need to add it to the volume group,…and we know how to do that too,…but now instead of extending the logical volume…to consume this new space,…we need to tell LVM to move the data…from our old drive somewhere else in the pool.…For that, we can use the pvmove command.…We have two options here.…
We can either tell pvmove…to move all of the extents…from the old physical volume…to the new physical volume,…or we can specify the old physical volume…and LVM will just take care of…moving extents off of the old physical volume,…and figure out where to put them across the volume group.…The pvmove command takes a very long time…to move data between devices,…and that's why I'm not going through it interactively here,…and if you need to migrate a physical volume,…
Join instructor Scott Simpson, as he shows how to manage and optimize file storage on Ubuntu Linux. First, learn how to create, modify, and mount partitions and filesystems, and manage swap space. Scott then combines these basics into more sophisticated solutions using volume management, and shows how to secure Linux storage and configure disk quotas and backup policies.

- Mounting encrypted partitions
- Creating redundant storage with RAID
- Working with physical volumes, volume groups, and logical volumes
