需要格式化swap分区：% K; t3 q$ }+ P( O8 ^2 P. |
mkswap /dev/cl/swap
( i% W& P* n9 u1 Z
/ ~# y# o7 l. G/ Z# c1 S( D4 B: H, \# mkswap /dev/centos/swap 4 \ y+ O% Z/ h! Q( I
mkswap: error: /dev/centos/swap is mounted; will not make swapspace, H f( w z& T5 z( M
需要swap不挂载才可以格式化：
! n2 U: ^3 }' s9 z" w9 `1 X, Z[root@controller1 ~]# swapoff /dev/centos/swap : j8 M3 s: q' t7 W8 o6 A+ `/ g
[root@controller1 ~]# mkswap /dev/centos/swap 7 c* T, Y! r( K& {
mkswap: /dev/centos/swap: warning: wiping old swap signature.
# }0 g0 d7 G) v4 \( ^Setting up swapspace version 1, size = 16773116 KiB3 e% I: R! ~8 ?! l8 q* y7 T0 W( x

[root@controller1 ~]# swapon /dev/mapper/centos-swap, i1 h! ^' x- B# ]$ P! ~
* ~( X8 H1 x; T* [9 k
再查看swap分区设置最高使用量时swap分区介入：3 ~5 m* J7 P$ x" B9 u
9 G% u! W8 Q6 K2 w- I: ecat /proc/sys/vm/swappiness7 |2 \4 r( @5 l4 k0 L
