Thanks a lot for irrefragable answer, Oliver! I have resolved the issue on one server (there was a little overdraft) and I'll try to resolve issue with fsck and /var when PROD will have lower load.
Thanks to all, Dmitry 2007/5/8, Oliver Fromme <[EMAIL PROTECTED]>:

There probably were some files that were removed, but some processes still had them open. du(1) doesn't see those files, so they're not included in the sum. df(1) sees the allocated space, of course. It can happen on the /var file system if an error occurs during log file rotation, so the programs writing to the log files (e.g. syslogd) are not properly informed about the rotation, so they keep the old files open. A good way to view such files/processes is to use the command "lsof +L1" (lsof can be installed from the ports collection: /usr/ports/sysutils/lsof). It lists all file descriptors in use that have a link count of zero. The correct way to resolve the issue is to find those processes and tell them to close the files (usually a "kill -HUP" will do that). If everything else fails, kill the processes (use "kill -KILL" if necessary). Do not use "umount -f". > But I have new problem. > fsck -y does not fix anything. That only works when the file system is not mounted (or only mounted read-only). It's usually done in single- user mode. (However, I assume that your file system doesn't need fsck, but it certainly wouldn't hurt either.) Best regards Oliver -- Oliver Fromme, secnetix GmbH & Co. KG, Marktplatz 29, 85567 Grafing b. M.
