How is it possible to have the stats below: 11G used over 40G Size and no more space available. Now I cannot send my e-mail because I receive: An error occurred while sending mail. The mail server responded: Error while writing spool file. Please check the message and try again.

root@ip-a-b-c-d [~]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/vzfs              40G   11G     0 100% /
none                  512M  4.0K  512M   1% /dev

Can you help me solve this issue ?

  • There are open deleted files, which can be released by restarting the relevant services, but in this instance it doesn't seem to be the problem. – ThatGraemeGuy Aug 26 '14 at 10:38

    /dev/vzfs would be Virtuozzo File System, I assume. I wonder if the underlying storage is over-committed, or something like that. This might be one for your hosting provider. – richardb Aug 26 '14 at 11:08

This can happen if you delete large files that a process has open (eg, large log files are a common example). If the application doesn't reopen the files, the old file handle sticks around and the space cannot be reclaimed.

If you know which file you deleted and which process owns them, you could try restarting that process. Or, restart your server and the space should get freed after that
