bug: cap deploy时服务器临时文件夹 /tmp 空间太小 Net::SFTP::StatusException (Net::SFTP::StatusException write /tmp/

overflow 1.0M 1.0M 0 100% /tmp
可以看到 /tmp 空间大小只有 1.0M 。
仙子要扩大 /tmp 的大小 请参考：Not enough space on /tmp
solution:
What seems to have happened:
Your / was full, then Ubuntu created a new partition, in RAM memory, to use temporarily.
Now, this 1MB partition is not big enough for the job, either.
What we can do:
1) increase the size of this partition just to do the upgrade
2) actually delete enough files in the HD that this partition is no longer needed.
To do 1:
open a terminal and run
sudo umount /tmp
sudo mount -t tmpfs -o size=1048576,mode=1777 overflow /tmp
This should give you an 1MB partition (just like the one you had =P).
Now, to increase the size, you increase the size in that line, so that, with size=10485760, you'd get 10 MB.
Your goal is to find a number that is enough for the job, but leaves enough ram too
首先删除 /tmp 文件夹 然后再建一个容量更大的时 出现 ： device is busy.
umount: /tmp: device is busy.
(In some cases useful info about processes that use
the device is found by lsof(8) or fuser(1))
你可以输入：
lsof /tmp #解决 device is busy
sudo umount -l /tmp #删除 /tmp
mount -t tmpfs -o size=1048576,mode=1777 overflow /tmp
sudo mount -t tmpfs -o size=1048576000,mode=1777 overflow /tmp
然后 /tmp 文件夹，被增加到 1000M
