sublime unable to save mounted files

Question

edit: it turned out that the hard drive of my dev box is broken.

original:

I do this every day, but it suddenly down today. I tried restart.

1. I mount to my devbox

   sshfs -o cache=yes root@zh*****:/var/www www
   

2. Then I

   ssh root@zh*****
   

   and go to www/app open sublime there and edit files

The problem is whenever I want to save file, Sublime says "Unable to save ~/www/app/**.js"

Also I can't open files on devbox through vim. And also I got this connection error when I try to run my node server on devbox (which never happened before). I'm not sure if this is related but they happened together.

$node-dev app/start.js
Server started on port: 3000
Error: connect ECONNREFUSED

Answer 1

First make sure your files have correct permissions set up.

IIRC everything you do through sshfs by default is made via user fuse, so I would try connecting to sshfs as a concrete user without cache (remove -o cache=yes) and your user's uid and gid. You may also change the encryption algorythm to something faster as this is a dev box. This can be done by:

sshfs -o uid=1000 -o gid=1000 -o ssh_command="ssh -Cc arcfour256" root@zh*****:/var/www www

Replace the uid and gid from your user on the server:

1. Do cat /etc/passwd on the remote machine
2. Find your user, will be something like root:x:1000:1000:,,,:...
3. First integer is the uid and the second one is gid.
4. Replace them and try remounting sshfs
