需要格式化swap分区：
0 a8 W' E# B% `* A" I: y' Amkswap /dev/cl/swap8 W% n" q4 G1 V* ]( ~) R ~ Y1 M# U
' |1 h8 t# B: f, d
# mkswap /dev/centos/swap , W6 X- l1 c' k7 P4 p; j. h4 ]
mkswap: error: /dev/centos/swap is mounted; will not make swapspace" u% w: \; X+ N2 z, a
需要swap不挂载才可以格式化： \3 s; H0 L! [2 b; F8 C' |
[root@controller1 ~]# swapoff /dev/centos/swap 4 b& @. u& \; p" B% C' J
[root@controller1 ~]# mkswap /dev/centos/swap 1 W% n1 Q* z7 e9 w6 d! Y
mkswap: /dev/centos/swap: warning: wiping old swap signature.

再查看swap分区设置最高使用量时swap分区介入：! v3 r! [$ x0 R! a0 r1 A5 [' v
& ?: `% s( s+ K
cat /proc/sys/vm/swappiness
