Solution 1

The session save handler needs to be able to write on the disk. The file system denies writing. That's causing your issue.

Change the session save path to a writeable directory.

Solution 2

If you're using PHP FPM and have set session_save_path in your pools, make sure you add a forward slash before the directory (absolute URL). This is what the problem was for me.

I am trying to register as a new user on a Symfony 2 project, i've been working on. This popped up all of a sudden. It was working in office yesterday, and I've setup a similar setup at home. I got:

Warning: session_start(): open(/var/lib/php5/sess_ibfocfkgbpfaoimac34nkjotp2, O_RDWR) failed: Read-only file system (30) in /home/projects/notes/app/cache/dev/classes.php line 406

Whats wrong?

Any idea why this might have popped up suddenly? Havent saw this error before. Anyway, I tried chmod 777 /var/lib/php5 -R, still got that error. Set the session.save_path = /tmp, restarted apache, still same error (PHP tries to save still in /var/lib/php5)

Oh, I made a mistake it was redirecting me to the remote server ... but why does PHP not set it to tmp by default? /var/lib/php5 is owned by root for me by default on Ubuntu?

Check your php.ini file, the defaults are configured in there.
