使用parted进行
1. 停用swap
alexis@Smilodon:~$ sudo swapoff /dev/sda8 alexis@Smilodon:~$ free total used free shared buffers cached Mem: 4121288 2880356 1240932 0 412184 801568 -/+ buffers/cache: 1666604 2454684 Swap: 0 0 0
2. 删除sda8
alexis@Smilodon:~$ sudo parted /dev/sda rm 8 Information: You may need to update /etc/fstab.
3. 创建新的swap
alexis@Smilodon:~$ sudo parted /dev/sda mkpart logical linux-swap 319.8G 320G Information: You may need to update /etc/fstab.
4. 启用swap
alexis@Smilodon:~$ sudo swapon /dev/sda8 alexis@Smilodon:~$ free total used free shared buffers cached Mem: 4121288 2896220 1225068 0 412492 801732 -/+ buffers/cache: 1681996 2439292 Swap: 266236 0 266236
5. 修改/etc/fstab
获取swap的uuid并修改fstab文件里的swap的uuid
alexis@Smilodon:~$ sudo blkid /dev/loop0: UUID="8569e038-5c7f-4a6c-995c-9d17fb6159f8" TYPE="ext4" /dev/sda1: LABEL="System Reserved" UUID="E8A0B48FA0B465AA" TYPE="ntfs" /dev/sda2: LABEL="System" UUID="4C3CC8203CC806C4" TYPE="ntfs" /dev/sda3: LABEL="Software" UUID="728862218861E457" TYPE="ntfs" /dev/sda5: LABEL="Work" UUID="8C9499F69499E2CE" TYPE="ntfs" /dev/sda6: LABEL="Entertainment" UUID="EE00B65A00B62A0B" TYPE="ntfs" /dev/sda7: LABEL="Sabretooth" UUID="8cdba6ad-fe73-4f87-8026-c5c8336b97df" TYPE="ext4" /dev/sda8: UUID="935637ec-2f43-4dd9-b7df-3a38dcb040fe" TYPE="swap"
# /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed. See fstab(5). # # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc nodev,noexec,nosuid 0 0 # / was on /dev/sda7 during installation UUID=8cdba6ad-fe73-4f87-8026-c5c8336b97df / ext4 errors=remount-ro 0 1 # swap was on /dev/sda8 during installation UUID=935637ec-2f43-4dd9-b7df-3a38dcb040fe none swap sw
如果仅仅是增大swap，也可以用下列方法进行
dd if=/dev/zero of=/home/alexis/swapdev bs=1M count=128 #生成大文件 mkswap /home/alexis/swapdev #格式化成swap swapon /home/alexis/swapdev #启动swap
