cannot remove Read-only file system
everything was working fine.
10 min ago I had Piwik (tracking script made in PHP) asking me to set the right permission for my folders. (the tmp folder).
The tmp folder in piwik insatllation root has the right permission.
So I decided to deleted and create it again and... it's not working :-(
One of my errors:
rm: cannot remove `tmp/cache/tracker/piwikcache_1.php': Read-only file system
and so on with every file.
I don't know where to watch :-(
