Debugging Common Problems With Using MogileFS

Unable to store files

1. Does the user mogstored is running as have permission to write to files on var/mogdata/devN * ?
2. Does that user own the /var/mogdata/devN directory?
3. Is there at least min_free_space free on the device? (Default: 100MB)
4. Are all machines using accurate time? In particular, trackers and databases should have time that's in sync, otherwise devices will not be considered writable because the device report from the monitor in the database (which uses the database's time), will be older than tracker's localtime - max_disk_age .
