553 Disk full

A customer contacted me today saying that they could not upload files via FTP, as they were getting the following error message:

553 Disk full – please upload later
Disk full – please upload later
Failed [Disk full - please upload later]

I found that PureFTP has a directive in it’s configuration file that stops files from being uploaded when the total disk usage is above a certain amount. The directive is:

MaxDiskUsage 90

To fix the problem, I simply raised that limit, restarted PureFTP and cleared out a few old files that were filling up the disk.

Problem solved!
