I tried to search the archives and found some stuff related but didn't
seem to fix the issue so I thought I would ask. If this has been
answered before please just a quick link to the answer and I will be
very grateful. Thanks!
I'm working on a number of Sun servers which run an application server
(Broadvision). It uses CORBA as it's underlying framework and all the
servers write to a log file 'orbixd.log' (they use IONA for the ORB).
After a while this log file grows quite large and we want to rotate it
so that we can keep space usage down. I have tried the following:
1) Making a copy of the log file to a different name (with a timestamp)
and then cat /dev/null > orbixd.log or cp /dev/null > orbixd.log or some
incantations of sed in the form of sed '1,<last line>d' orbixd.log >
orbixd.log (I realize that's a little crazy since it's going to blow
away the file once it's opened but it was suggested by tech support).
The file will go to zero bytes for all of a couple seconds and then pop
back to 550+MB (as displayed with ls -la).
The size returned from du -sk is about the correct size (very small).
When I cat the file I notice after doing one of the methods that the
file is empty, and has *lots* of empty space at the beginning of it (but
then wc -l reports something like 2000 lines, for a 550+MB file).
We have not removed the file (the servers aren't writing to an inode
that I can't see which is the usual variant on this question). I just
can't clear the file out.
Note: This is a file system mounted on an EMC array. And this is a
special 'image' that has been developed for this company (certain items
have been removed such as all the man pages, etc).
cheers
