I fixed the nfslock issues. For some reason nfslock has to run on the
client. So I did "service nfslock start" and that fixed the kernel
errors. However nfcapd still complains when I stop it (not errors when
it's running):

Apr 14 23:03:11 pandora4 /usr/local/bin/nfcapd[6337]: ioctl(F_WRLCK)
error in nfstatfile.c line 339: Input/output error
Apr 14 23:03:11 pandora4 /usr/local/bin/nfcapd[6337]: Terminating
nfcapd.

Also the files are ok and nfsen is able to read them and generate the
graphs. So I guess I can ignore those.

Now I'm back to my original problem: nfsend is not updating the size for
the live profile. I see the graphs, I can query the flows, get
statistics, etc., it's just the size of the live profile that is not
growing. The other profiles are fine. I also don't have this problem on
the devel machine where both nfsen and nfcapd are on the same machine
and nfcapd writes locally.

So could this be NFS related?

This is how i mount the share:

artemis:/opt/data/netflow       /data           nfs     rw    0 0

I also tried:
artemis:/opt/data/netflow       /data           nfs
rw,hard,intr,tcp,lock    0 0

Still no luck!

All is ok if I run nfexpire manually: nfexpire -p -r /profile_data &&
nfexpire -p -s 900G -w 90 -e /profile_data

I also run did: sudo -u apache command and it was ok.

selinux completely disabled on both the analizer and the collector.

There are no errors in the logs:

It seems that nfsend is not able to update the .nfstat. It only gets
updated when I run nfexpire manually.

Could this be related to Fedora or the nfs version?

(profile.dat doesn't get updated)

 
Hi Peter,

Sorry for replying so late. I've been busy rebuilding everything from
scratch. :-)

I'm thinking it's NFS related. I assume that for some reason nfcapd is
not able to lock the files or something like that. We have a distributed
setup: 3 collectors writing to a network share using NFS v3. I only get
errors when I stop the nfcapd (no errors when I start it):

Apr 14 17:40:25 pandora4 kernel: lockd: cannot monitor 10.0.0.194 Apr 14

Is there a better way than writing to the share in real-time? Maybe
write locally and rsync hourly or something like that?

Thanks,
Bogdan.

Hi Bogdan,
It looks like that your nfcapd collector processes can not update the
stat files.
Make sure the UID for nfcapd can write and update the files. Also check
the syslog daemon message file, as problems are reported there. Make
also sure that any SElinux policies are set correct if you have them in
place.
Let me know about the results

    - Peter
