kernel process [nfscl] high cpu
Hi,
On a 10.1-RELEASE-p9 server I have several NFS mounts used for a jail.
Because it's a server only to test, there is a low load. But the [nfscl]
process is hogging a CPU after a while. This happens pretty fast, within
1 or 2 days. I'm noticing the high CPU of the process when I want to do
some test after a little while (those 1 or 2 days).
My jail.conf look like:
exec.start = /bin/sh /etc/rc;
exec.stop = /bin/sh /etc/rc.shutdown;
exec.clean;
mount.devfs;
exec.consolelog = /var/log/jail.$name.log;
#mount.fstab = /usr/local/etc/jail.fstab.$name;
test01 {
host.hostname = test01_hosting;
ip4.addr = somepublicaddress;
ip4.addr += someprivateaddress;
mount = 10.13.37.2:/tank/hostingbase /opt/jails/test01
nfs nfsv4,minorversion=1,pnfs,ro,noatime0 0;
mount += 10.13.37.2:/tank/hosting/test
/opt/jails/test01/opt nfs nfsv4,minorversion=1,pnfs,noatime
0 0;
path = /opt/jails/test01;
}
Last test was with NFS 4.1, I also worked with NFS 4.(0) with the same
result. In the readonly nfs share there are symbolic links point to the
read-write share for logging, storing .run files, etc. When I monitor my
network interface with tcpdump, there is little nfs traffic, only when I
do try to access the shares there is activity.
What is causing nfscl to run around in circles, hogging the CPU (it
makes the system slow to respond too) or how can I found out what's the
cause?
Regards,
Frank de Bot

Well, the nfscl does server-client RPCs referred to as callbacks. I
have no idea what the implications of running it in a jail is, but I'd
guess that these server-client RPCs get blocked somehow, etc...
(The NFSv4.0 mechanism requires a separate IP address that the server
can connect to on the client. For NFSv4.1, it should use the same
TCP connection as is used for the client-server RPCs. The latter
seems like it should work, but there is probably some glitch.)
** Just run without the nfscl daemon (it is only needed for delegations or
pNFS).
Since a big Netapp filer (the cluster ones) are about the only servers
that currently support pNFS (no FreeBSD server support yet), you can
probably forget about pNFS (I'd get rid of the pnfs mount option).
It also won't work unless this callback path is working.
As for delegations, they aren't required for NFSv4.[0-1] to work correctly
and aren't enabled by default on the FreeBSD server.
-- Running without the nfscl daemon will just ensure no delegations
are issued, even if enabled on the server.
