Hard disk lock down.
I am operating an server with P3 850*1, 512MB, 90GB storage. (two 45GB)
blue:~# df -H
Filesystem Size Used Avail Use% Mounted on
/dev/hda1 2.0G 233M 1.6G 13% /
/dev/hda3 32G 2.6G 27G 9% /var
/dev/hda4 10G 646M 9.1G 7% /premium
/dev/hdb2 43G 9.2G 32G 23% /home
sometimes when my user commands "mv" or "chmod" in telnet or ftp,
directory are locked down. (under /home)
so any user(even root!) enter that directory and command in that directory
until reboot the system.
this situation is not usual. but sometimes occurs.
So I have to monitor always and reboot the system!!
another important thing is that while system is in that situation,
system's load is higher and higher. even 37 in result of "uptime".
what cause this problem?
