需要格式化swap分区：+ F0 c0 s# ~5 h4 F! E5 @
mkswap /dev/cl/swap* u" W/ H+ a7 v
, }$ j) d$ C5 t* [/ H+ [# mkswap /dev/centos/swap
' ~( b! v! M4 ^: J6 Y7 imkswap: error: /dev/centos/swap is mounted; will not make swapspace
, y6 r$ M5 ~& L( `1 `& i) N需要swap不挂载才可以格式化：2 d5 b! e7 w8 d4 _
[root@controller1 ~]# swapoff /dev/centos/swap
+ ~' J0 K& C0 V% I[root@controller1 ~]# mkswap /dev/centos/swap
0 R( m' ?, t) M z) ^) kmkswap: /dev/centos/swap: warning: wiping old swap signature.8 B" B( z3 F! ]5 A

' }$ k5 _9 `$ s5 Q+ O8 U; s; Ono label, UUID=ab0692e6-84f7-43a3-bdb2-1910d8fb8042. _1 t# n/ n) p1 {- w+ G

再查看swap分区设置最高使用量时swap分区介入：9 q& M4 c) I* V: E
