Question

Update of disk space usage information without rebooting

Asked by: atyur

Because of large log files I run from time to time out of space on my mail-server (CentOS 5.3). After removing old log files I see the same information about the space usage and have to reboot the server to update it. Is there a way to update space usage info without rebooting the server?

Where is this information that you are seeing? If there is a message what is it?

if you delete files that are open by some running processes then you need to find out these processes and some how either stop it or force it to close these files. Space will not be released till these processes close the files or terminate.

you may use fuser or lsof to find which process uses which file

Assuming the log files are generated by syslog, then do

service syslog restart
