I am confused by a warning from mkswap :
When making a swap on a LVM volume, I see the following warning :
mkswap: /dev/vg_SDB1/swap_test6_64: warning: don't erase bootbits
sectors on whole disk. Use -f to force.
Setting up swapspace version 1, size = 1048572 KiB
Is it safe to use mkswap -f in this case ?
(If that matters, the swap is intended for a virtual machine, and
the host where I am using mkswap is a CentOS-6 server.)
