Is there a trick to mounting swap in n a lvm? I can't get it to work.
[root@localhost ~]# swapon -va
swapon on /dev/mapper/VG-lv_swap
swapon: /dev/mapper/VG-lv_swap: found swap signature: version 1, page-size 4, same byte order
swapon: /dev/mapper/VG-lv_swap: pagesize=4096, swapsize=4294967296, devsize=4294967296
swapon: /dev/mapper/VG-lv_swap: swapon failed: Device or resource busy
