Re: [hobbit] I'm getting the error "could not lock RRD"

Well, something fixed it and I'd rather not break again it while
fiddling around to try to find out what it was!

The nfs config is straight out of the box, nothing special and
everything else runs ok. Maybe it was something corrupt in the data
files and clearing them after moving the directory cleared the
problem.

I am running my rrd files on an NFS share, having no problems. Have also

files on NFS mounts. Have been running Hobbit server with both the app
binaries and rrd files on an NFS mount, for more than a year now. Unless
there are some NFS performance issues on your network, housing those
files on an NFS mount isn't the problem.

Got it working! I moved the data directory to the local disk and
deleted the contents. After a while it all started working.

rrd obviously doesn't like nfs shares.
