I have website working fine before. But now its not able to connect to the server(I believe that is the problem). But its strange that the message not able to connect to the server is not coming and its keep connecting... for infinite time(its been 3hrs). And then I discovered the the apache is in sleep mode. Does that causing the problem ?

Here is the output of ps aux

Could you suggest any particular unnecessary file that I can clean to back everything to normal condition(temporarily). (i.e. any log or archieve or anything ) ?

  • Hi @Wooble the problem seams to be short out. My server do not have much space so that its not able to take any request. Please check the updated question . Please let me know how to clean some unnecessary file/folder to make space. It would be better if you could answer(and explain) this rather than comment. – Subhransu Mishra Sep 13 '12 at 12:11
  • @Wooble Thanks, I respect your comment. But the question is being asked in programming point of view initially. – Subhransu Mishra Sep 13 '12 at 12:53

Cannot write to “index.html” (No space left on device).

Seems you have a disk full.

Run a

du -sk /* | sort -n

to see where your space is going. Might also be into "deleted" inodes, and if so you'll need to check where they are by checking /proc filesystem. To make the space reappear, you have to restart whatever the process is that is holding that file descriptor(s).

For systems like yours, usually space "disappears" in:

  • unrotated logs in /var/log or somewhere else
  • rotated and archived, but not removed (i.e. archived somewhere else) log files
  • temporary files in /tmp
  • uncollected Web sessions in "wherever your session save directory is"
  • temporary Web upload files in "wherever your temporary upload path is"
  • MySQL binlogs
  • old mail notifications (e.g. cron receipts).

I'm sorry, but without looking at the server configuration there's not very much that can be done.

As emergency procedure

NOTE: when doing some of the tasks below, you will notice that space seems to disappear. I.e., you delete a 50 Mb file, and free space remains zero. This means that some of the processes are finally dumping and saving their data to disk. As long as this keeps happening, do not restart the system if it can be avoided (data still in RAM will be lost), and do not stop any processes.

  • Stop Apache (apachectl stop, apache2ctl stop). This will prevent more load on the system, which is the most urgent thing, and possibly free some further temporary space. Stopping Apache does not risk losing data (perhaps some logs, but that's survivable).
  • check /tmp directory for unneeded files (do not just remove everything: CHECK it)
  • check mail queue with mailq command, just in case
  • verify that there is no useless mail in /var/spool/mail/somewhere (if there is, you can probably delete it)
  • if site is PHP, inspect PHP.ini to know where temporary file upload and sessions are
    • delete all session files (usually phpsess_*)
    • delete all temporary upload files
  • check all /var/log/ log files
    • delete useless and/or very old ones
    • place any .gz or .bz2 files somewhere else with FTP or scp
    • Check there are no unrotated log files (logs REALLY big).
      • if there are, in a pinch, zip them with gzip - be sure you have enough free space: to zip a 1 GB log file it's better to have 200 M free at least. Afterwards you'll have a whole GB free, but meanwhile, you need that free buffer space.
      • remember to configure correctly logrotate later.
  • ONLY if you have now enough space (about same size of database):
    • stop MySQL and restart it, to flush data, free temp space and start solid
    • verify there were no corruptions due to space unavailable
    • if necessary and possibile, purge master logs (see MySQL manual/site)
    • If you do not have sufficient space, choose the biggest Apache logs and move them out of the way on another server through FTP or SCP. Do not delete those logs, especially error logs. Then do the MySQL stop-restart thing; a MySQL kept running on a full system is a Bad Thing.
  • check Apache virtual hosts and their logs.
  • perhaps not useful to solve this emergency, but check big error.log files. This command will tell you the seven (you can ask for more) most frequent errors, that are not only responsibile for big, disk-eating log files, but also symptomatic of problems in the web site (or attempts to make problems): cut -f4 -d']' < /full/path/of/the/apache/error.log | sort | uniq -c | sort -rn | head -n 7
  • check all virtual host directories with du: if some of them are very big, investigate why (old backups? Useless media files? Rogue malware repository installed by hackers?). Again, you stand to gain space but also find possible problems.
  • restart Apache.

  • run this command:

    ls -la /proc/*/fd/* | grep deleted

  • if you see any "deleted" files, for example "/proc/3297/fd/4", then check with ps what process has PID 3297 and try restarting it, if possible and if it is safe to do so. This will free any space hogged by "temporary" deleted inodes.

Finally, do try and get a larger disk :-)

Some of the steps above (e.g. checking log files) should be performed periodically to ensure that new problems don't crop up.

(And no, unfortunately the list is far from being exhaustive)
