运行 mkswap 命令将整个 10GB 分区变成交换空间。
[root@studentvm1 ~]#mkswap/dev/mapper/fedora_studentvm1-swap
mkswap:/dev/mapper/fedora_studentvm1-swap: warning: wiping old swap signature.

[root@studentvm1 ~]#
重新启用交换空间。
[root@studentvm1 ~]#swapon-a
[root@studentvm1 ~]#
现在，使用 lsblk 命令验证新交换空间是否存在。同样，不需要重新启动机器。
[root@studentvm1 ~]# lsblk
