File Systems problem
Posted on 1997-07-03
During the last weeks, in which the cpu (i585 120mhz) of
my machine has been heavily loaded (steadily 100% cpu busy),
i noticed two weird facts
- after 8-9 days, the system claimed the / and /var file
system to be readonly. They were, in effect; root couldn't
create or modify any file in those directory. log files
in /var/log had not been updated since one day before.
Strangely 'ls' command showed the correct access privileges
for /var and /:
%% ls -lF /var -d
> 1 drwxr-xr-x 15 root root 1024 Jun 9 19:32 /var/
'df' accessed correctly to all file systems, too.
Yet all programs that require accessing to data in those areas
were in troubles (mail programs, man, etc.; not even /etc
could be accessed, of course).
I got out of troubles using remount with options:
%% mount -n -o rw,remount /
%% mount -n -o rw,remount /var
I guess this problem is connected to the extreme loading of the
machine, but i am not sure. Can anybody explain me what has
What is the best way to monitor the system, so as to be able to
restore the normal situation as soon as possible?
- two local directories ~/var and ~/etc disappeared one night (that
is, they were not detected by 'ls' any more) and came back the
How can it be? What can I do in such cases?
Thank you for you comments
