[y/n]The only command I could find to help was swapoff, but the only result is BAD ARGUMENT (even though when I looked at examples of swapoff's use, it is to be used on the /dev/sd* devices).
VGEXTEND: How to avoid wiping a swap signature in /dev/sda3?
linux;lvm;swap
You want to use /dev/sda3 as a new LVM PV./dev/sda3 was previously used as a swap device.You have 2 choices:Overwrite/wipe the previous contents of the device and make it an LVM PV.Don't overwrite, leave it alone, and abort the operation. Naturally, it will not become an LVM PV.You cannot have it both ways. If you want to use this device as an LVM PV then answer yes. If you realized that you made a mistake and this device is indeed supposed to be a swap device then answer no.
