I'm getting the error "could not lock RRD"

Hi
What I should have added is that I am seeing graphs but with no graph
lines and no numeric data in them. The filesystem graph for example,
shows all my mount points but then where the numbers are supposed to
be it is showing nan.

I'm trying moving the data/rrd directory to a local disk now, I'll let
you know how it gets on.

Rrdtool by itself is not sufficient for all the libraries hobbit needs.
Please check the list of installed libraries against the hobbit
pre-requisites & install any missing libraries. Then, when you
re-compile hobbit afterward, run "make clean" before running "make" and
"make install". The "make clean" command is important.

I built hobbit from source and initially it complained that the
libraries weren't there so I installed the rrdtool package and tried
again. This time it built so I assume that it had all it needed.

If you can let me know which files need what permissions I'll check
when I check the nfs share suggestion later.

I've seen this rrd error in the past when rrd libraries, binaries, or
data files had incorrect permissions or were missing (unavailable).

Hi
The directory is a nfs share. I'll try moving the data directory to a
local disk and see if that fixes it.

could not lock RRD

It's an error from the rrdtool library. I honestly have no idea what
could be causing this.

Is the /var/sites/hobbit/non-secure//data/rrd an NFS filesystem?
Perhaps there's some issue with locking on networked filsystems.
