Hello All,
I have been running FBSD a long while, and actually running since the 5.x
releases on the server I am having troubles with. I basically have a small
network and just use NIS/NFS to link my various FBSD and Solaris machines
together.
This has all been running fine up till a few days ago, when all of a sudden
NFS came to a crawl, and CPU usage so high the box appears to freeze almost.
When I had 6.1-RC running all seemed well, then came the announcement for the
official 6.1 release, so I did the cvs updates, made world, kernel, and ran
mergemaster to get everything up to the 6.1 stable version.
Now after doing this, something is wrong with NFS. It works, it will return
information and open files, just it's very very slow, and while performing a
request the CPU spike is astounding. A simple du of my home directory can
take minutes, and machine all but locks up if the request is done over NFS.
Here is top snip:
PID USERNAME THR PRI NICE SIZE RES STATE C TIME WCPU COMMAND
497 root 1 4 0 1252K 780K - 2 50:42 188.48% nfsd
This is a nice IBM eServer with dual P4-XEON's and a couple GB or RAM on a
disk array, and locally is screams, heck NFS used to scream till I updated. I
am not really sure what info would be useful in debugging, so won't post tons
of misc junk in this eMail, but if anyone has any ideas as to how best to
figure out and resolve this issue it would sure be appreicated...
Are you running rpc.lockd? I've had very bad luck with it since
sometime in the 5.x series... especially with it interoperating with
Solaris. I submitted a PR on it, but it's apparently broken in about X
ways. If possible, I would suggest living without rpc.lockd for now (if
you're currently living with it that is)
Other than that issue, NFS itself has been working nicely for me.
