Try using this magic incantation of lsof:
sudo lsof -nP +L1
This will list all filenames that have been deleted but have filehandles
still being held open by a process. The "+L1" means to show all files with
a link count less than 1. Deleted files have a link count of zero.
However, I suspect this cannot be your problem, because a new xymond_rrd
process would simply create a new file with the same filename. A
deleted-but-still-present file has no filename on the filesystem and so
cannot block the creation of a new file with the same name.

Hi all,
I’m writing a custom script to monitor a group of run

Anyway, I’m trying to create a graph, which I’m never
good at.
Anyway, the rrd file was created immediately, when I
first put in the entry to TEST2RRD and a NCV_Testname line in
xymonserver.cfg.
A couple of iterations of the data, changing names etc.
I deleted the rrd file (which was updating some data), killed the rrd
processes to the xymon server. It didn’t recreate the file. So I restarted
xymon completely on the server.
All I could think of is a process holding on to that old
file.
So does anyone know the magic to get an RRD file to
recreate on the server?
BTW, a second server that also has the test, does have
the rrd file, and it updates the current data, but no historical data.
Thanks
Paul.
