When "/etc/init.d/nfs stop" is run it normally makes sense to stop all NFS client usage, unmount the filesystems and kill the support services. However when we are only stopping so as to install a new version, that doesn't make so much sense, particularly when installing over NFS. So my question to someone in the "Installation" team is "How can I tell in '/etc/init.d/nfs' whether this is just part of an installation stop-and-restart, or if it is a real user-requested or at-shut-down stop?

This restart_on_update is meant for daemon processes to be restarted upon package update to make sure the new binary is running. I think it would make more sense for a "reload" in case of update the way the current nfs script is written: reload does a restart of all possibly running daemons, and that is all that is needed. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Setting NEEDINFO: Jano, what zypper does (similarly to Installation adjusting YAST_IS_RUNNING) that upgraded RPMs don't do dangerous actions?

Nothing. The rpms are supposed to work even with plain rpms, they should not do any dangerous actions :O) AFAIK, YAST_IS_RUNNING is just telling the packages to avoid running suseconfig, since yast will do it once for all at the end of installation. Nevertheless, zypper does not set this variable, as this solution should be replaced with a better one at the RPM level (see bug 365649). -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

It runs /etc/init.d/nfs try-restart which stops and restarts nfs. I suspect the problem here is that restart also unmounts and remounts all filesystems - but only remounts those that are listed in /etc/fstab. So if you have mounted a filesystem by hand (as I suspect Jon did), then it will get unmounted and then lost. I think I will change 'restart' and 'try-restart' to not do any unmounting or mounting. It will just stop and restart the relevant daemons.

Will that work in the context of SuSEfirewall (which, for NFSv3, uses obtains the rpc port numbers dynamically) or will they remain bound to the same port?

That is a very good point. statd is the only service which this might be a problem for. If statd was started without specifying a port to use (as is normal) it will typically choose different ports numbers for UDP and TCP. If we kill and restart it, it is not possible to ask it to choose the same two port numbers. If a port number is specified, it will be used for both UDP and TCP. So the options seem to be to either - rerun the firewall rules after restarting statd - not restart statd if there is a firewall active. - hard code a number to be used by statd always While the last would be simplest, it is not possible to choose a number that will always be free. The second would also be fairly simply I suspect, if we found a security hole in statd, we would really want it to be restarted on an update. So that leaves the first option. I think that would be if [ -e /sbin/SuSEfirewall2 ]; then if /sbin/SuSEfirewall2 status < /dev/null > /dev/null then /sbin/SuSEfirewall2 on > /dev/null fi fi Ludwig: I think you are the maintainer of SuSEfirewall2 - would that be a safe thing to put in /etc/init.d/nfs to run after 'statd' has been restarted in response to "/etc/init.d/nfs restart" ??

I have modified /usr/sbin/start-statd to restart the firewall after starting statd, and have modified "try-restart" in /etc/init.d/nfs to only restart the daemons, not the mount points, and to use /usr/sbin/start-statd to restart statd. I will attach the new 'start-statd' and 'nfs' scripts. I think it is too late for these to get in to 11.2. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
