I got this message when I tried to enroll on my site as a student would via email confirmation.
Warning: Unknown(): write failed: No space left on device (28) in Unknown on line 0
Warning: Unknown(): Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/home/qhss/public_html/moodle/uploaddata/sessions) in Unknown on line 0
What in the world happened here?
"No space left on device" means the disk is full. Notify your ISP.
I ran a cron and I believe it may have solved the problem. But now I have another problem
The email confirmation that the user gets does not show the full path to the confirmation page. The email says something like:
A new account has been requested at 'Any organization'
using your email address.
To confirm your new account, please go to this web address:
/moodle/login/confirm.php?p=jcrFDhyP8yoUmYe&s=g
Notice that the domain is missing.
It should read http://anyorganization.com//moodle/login/confirm.php?p=jcrFDhyP8yoUmYe&s=g
Do I fix this in the config file?
I think it's highly unlikely that sessions files would cause a disk full error. The sessions files are quite small <2.5K in size.
The PHP interpreter itself is supposed to handle cleanup of stale session files. Even if that somehow got broken, you would need hundreds of thousands, if not millions of stale session files to use up a lot of disk space on modern disk drives.
Unless you are running Moodle on obsolete hardware, the typical cause of a disk full error would be some runaway (non-Moodle related) process which filled up the disk drive with garbage data. Another possibility would be users (or hackers) storing a lot of audio/video file-sharing data on the disk.
I don't see a sessions directory in my moodle data directory.
Is it sometimes somewhere else?
Permissions must be set to write to the moodledata directory, this may be the problem. Chmod to 777.
