无法删除分区

命令: fdisk -l

device start end blocks id system /dev/sda1 1 7182 57684992 83 linux /dev/sda2 7182 7494 2501633 5 extended /dev/sda5 7182 7494 2501632 82 linux swap

发现sda2和sda5的开始和结束都是一样的,只有blocks数不一样,差了一个块.

删除sda5,保存时.出现以下警告. warning:re-reading the partition table failed with error 16: device or resource busy. the kernel still uses the old table .the new table will be used at the next reboot or after you run partprobe.

重起之后,分区表还是没有被更新.

执行partprobe命令后,又出现下列警告. warning: partition 5 on /dev/sda could not be modified, probably because it is in use. as a result, the old partition will remain in use until after reboot.you should reboot now before making further changes.

重起之后,分区表还是没有被更新.

感觉sda2和sda5的分区很混乱,好像重叠在一起,所以sda1,sda2和sda5同时删除再保存.重起后,还是没有变化 已经不知道怎么办好了,哪位大虾告诉在下怎么办好啊
