我想在挂载的外部EBS,/ workspace上进行交换

我得到设备或资源很忙

swapon：/workspace/swap.1：swapon Failed：设备或资源忙

@H_403_5@sudo /bin/dd if=/dev/zero of=/workspace/swap.1 bs=1M count=10240 sudo /sbin/mkswap /workspace/swap.1 sudo /sbin/swapon /workspace/swap.1 Filesystem Size Used Avail Use% Mounted on /dev/xvda1 7.8G 5.1G 2.3G 70% / none 4.0K 0 4.0K 0% /sys/fs/cgroup udev 2.0G 12K 2.0G 1% /dev tmpfs 396M 336K 395M 1% /run none 5.0M 0 5.0M 0% /run/lock none 2.0G 0 2.0G 0% /run/shm none 100M 0 100M 0% /run/user /dev/xvdb 6.0T 1.7T 4.1T 29% /workspace

运行sync命令后仍无法正常工作

@H_403_5@➜ ~ sync ➜ ~ sudo /sbin/swapon /workspace/swap.1 swapon: /workspace/swap.1: swapon Failed: Device or resource busy

这是交换信息
