I have created a VG, and want to create a LV for swap:
$ sudo lvcreate -n swap -L 4G VG WARNING: ext4 signature detected on /dev/VG/swap at offset 1080. Wipe it? [y/n]: y Wiping ext4 signature on /dev/VG/swap. Logical volume "swap" created. $ sudo lvcreate -n root -L 40G VG Logical volume "root" created. $ sudo lvcreate -n home -l 100%FREE VG Logical volume "home" created.
What does that warning mean? What shall I do about it?
Why do the following two commands not have the warning?
