next in thread | raw e-mail | index | archive | help
I use FreeBSD 3.1 as an NFS server in an environment with almost
exclusively Solaris Sparc workstations. I needed an extra NFS server
for our "Daily Builds" so I grabbed an Dell Optiplex 264MHz PII with
64 MB RAM and I put in an extra 7200 rpm 14 GB IDE disk to export
using NFS. It is connected with 100 Mbit ethernet to a switch.
Problem is, it has problems working as an NFS server. The load is
heavy at time from up to three clients. But I expected a FreeBSD
system to deal with this at least as good as an old Ultra 1
SparcStation that I used earlier as an NFS server. Could you give me
hints about what the problem can be and maybe what commands to use for
monitoring the problem? I include the "dmesg" output at the end of
this mail.
The Solaris client get lots of "NFS server turkey not responding still
trying" and some /var/adm/messages
NFS create failed for server turkey: error 11 (RPC: Server can't decode arguments)
NFS create failed for server turkey: error 9 (RPC: Program/version mismatch)
NFS lookup failed for server turkey: error 10 (RPC: Procedure unavailable)
NFS lookup failed for server turkey: error 11 (RPC: Server can't decode arguments)
NFS lookup failed for server turkey: error 7 (RPC: Authentication error)
NFS lookup failed for server turkey: error 8 (RPC: Program unavailable)
NFS lookup failed for server turkey: error 9 (RPC: Program/version mismatch)
In the log file from one the daily builds there was two "I/O error"
writing to the NFS exported disk. The FreeBSD box has no /var/log/messages
that i can relate to this problems.
The FreeBSD machine has also rebooted a couple of times with no trace
of the cause in the message log. It has also lost network contact a
couple of times requiring a reboot (I don't have details about the
state it was in, I was not the one rebooting it). No heavy load at the
time for the spontaneous reboots or lost contact.
I suspect DMA is disabled from the dmesg output below, how do I enable it?
Can this be the problem?
Is the 64MB memory the problem?
Does the NFS errors above indicate ethernet card buffer overun?
Is there incompatibilities between NFS clients on Solaris 2.5.1 and
the NFS server on FreeBSD 3.1?
Or is FreeBSD 3.1 not stable enough? Should I switch to FreeBSD 2.X?
Or is it really true that IDE sucks? ;-)
