mkfs.ext4 hangs with 100% CPU when using an LVM logical volume
Issue
- Attempting to create an ext4 filesystem onto an LVM logical volume hangs, with the cpu at 100% and a forced shutdown is necessary.
- Creating an ext4 filesystem with mkfs onto a partition succeeds, but doing the same operation on an LVM logical volume hangs.
