setting specific lockd port for NFS .....................

setting specific lockd port for NFS .....................

[Terry Spaulding]

List....

Has anyone been successful in setting a specific port for lockd to use with
NFS ?

I am using SLES9 SP3 and have tried setting it in /etc/zipl.conf with no
success. It stills uses a port from portmapper rather then a port I am
specifying.

I have tried these two formats in /etc/zipl.conf:

example:

ramdisk = /boot/initrd
    parameters = "root=/dev/mapper/lun01r1 selinux=0 TERM=dumb elevator=cfq
nlm_tcpport=52670 nlm_udpport=52670"


example:

ramdisk = /boot/initrd
    parameters = "root=/dev/mapper/lun01r1 selinux=0 TERM=dumb elevator=cfq
lockd.udpport=52670 lockd.tcpport=52670"

Perhaps I am trying to set it in the wrong place ?

Any recommendations would be appreciated.

TIA .........................

I've never tried it myself, but...

I think you want to combine those two:

    lockd.nlm_tcpport=52670 lockd.nlm_udpport=52670

Thanks Neil, I will give it a try and get back to the list.

The nfslock init script in Fedora Core can do this...

Neil,

That worked on SLES9. I have the lockd using specific ports.

lockd.nlm_tcpport=52670 lockd.nlm_udpport=52670

 I will be testing the same on SLES8.

Thanks................

Neil,

I tried the same settings for lockd on the SLES8 system and the lockd
settings do not work in /etc/zipl.conf

I did some research on SLES8 and setting the lockd ports and found some
info that shows the zipl.conf noted
below works for SLES8 but there maybe some additional settings required to
support lockd port setting as a kernel parameter.

I found some references to using sysctl and another to use one of the /etc
conf files but no details on what was entered in these files.

We are planning on replacing all of the SLES8's but later in the year. Can
anyone shed some light on setting the nlm.lockd port on SLES8 ?

SLES8 is 2.4 based which does this a bit differently to 2.6.

Kernel parameters are lockd.udpport and lockd.tcpport
module parameters are nlm_udpport and nlm_tcpport.

I suspect the former is what you want to put in zipl.conf

Neil,

I changed the zipl.conf. The lockd is still setting the port randomly.

parameters="dasd=200-209 root=/dev/dasda1 lockd_tcpport=52670
lockd_udpport=52670"

ran zipl and rebooted.

Started nfs server on this Linux and issued rpcinfo -p:

    100021    1   udp   1024  nlockmgr
    100021    3   udp   1024  nlockmgr
    100021    4   udp   1024  nlockmgr
    100021    1   tcp   1078  nlockmgr
    100021    3   tcp   1078  nlockmgr
    100021    4   tcp   1078  nlockmgr

rpm -qa | grep nfs:

nfs-utils-1.0.1-79
yast2-nfs-client-2.6.11-51
yast2-nfs-server-2.6.13-41

kernel: Linux linux01 2.4.21-251-default #1 SMP Sun Sep 26 14:07:15 UTC
2004 s390 unknown

Any suggestions would be appreciated.

Thanks .............

Neil,

I found typo on the lockd statement.

I should have set the kernel parms as: parameters="dasd=200-209
root=/dev/dasda1 lockd.tcpport=52670 lockd.udpport=52670"

Lockd is now set correctly.

On to testing.

Thanks for your assistance.

Neil,

The NFS servers/Clients are working great on SLES8 and SLES9 with static
ports defined
for lockd.

Thanks for the help .....
