I have no real idea, but do you have good fstab options? did you read the *mount* man page?

These mounts are not done through fstab. I suppose they could be, but it was never needed in the past, and I definitely do some manual mounts on occasion. On 10.3 if I manually mounted drives, and then switched my network connection**, the mount would persist. On 11.1 the NFS mounts all drop immediately. **Switching my network connection using Network Manager. IP address stays the same. Other apps continue to work fine, as well as my smb mounts. It's just NFS mounts that croaks. I did look at the mount man page and did not see anything that looked like it would help.

You need to display the way you mount the nfs mount and the host table. I had that problem until I realize the following: 1. My machine, orion had 1 address for the wired 2. when it switched to wireless, the network switch another sub-network. Result I loss my connection. I fixed this by setting my mount point to 127.0.0.1. When I switch network, it no longer breaks the nfs mount. -- Joseph Loo jloo@acm.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Currently I mount them like: mount 192.168.0.22:/storage /home/user/shares/storage How do I switch the mount point to 127.0.0.1? 127.0.0.1 is in the hosts files as localhost.

Maybe in 10.3 the default option is to use UDP and in 11.1 is TCP?, try specifying "proto=udp" as an option.... Regards, -- Ciro Iriarte http://cyruspy.wordpress.com -- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Tried udp. Was able to mount it, but as soon as I pulled the network cable, the mount went away. Btw, when mine switches from wired to wireless, the ip addres stays the same, hence same subnet as well.

I assume that your nfs server is the same machine. If it is, just change the address to 127.0.0.1 and it will mount your machine. I personally like to make things a bit more symbolic by using a host name.

The NFS server(s) are on other machines. Possibly dumb question, what would the point be of mounting nfs on the same machine? Thanks, James -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

The reason is that I use autofs. This allows the nfs mounts to occur on a user by user basis. A user might be on the local machine or another machine. That way, the data follows the user not the machine. So if you couple ldap with the autofs, you can have a central area containing the user password and mount location. Then you can log onto any machine using ldap and your home directory will be mounted automatically. In addition, autofs allows you to have secondary servers to provide your data. If the primary server goes down, the secondary server will be taken over. You might want to change your option to soft, intr as part of your mount options. This should allow the nfs mounts to be interrupted. If you loose the mount, can you do a remount to get the data? -- Joseph Loo jloo@acm.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
AutoFS might be a good option too, it will mount the share on demand (each time a user requests to access the mount point. Regards, Ciro 2009/7/29, Joseph Loo <joseph.loo@dslextreme.com>:

I created an executable /etc/auto.shares and it has:
No need to make it executable; this is only needed for a real shell script emitting some dynamically calculated data - for an example, take a look at /etc/auto.net
storage rw 192.168.0.22:/storage mythtv rw 192.168.0.16:/mythtv

I tried this and if I make auto.shares NOT executable, then I get these errors in the log file when I try to access the mount: Aug 3 10:32:18 user-8710w automount[15947]: lookup_nss_mount: key "storage" not found in map.

That takes the errors away, but things still don't work.

Dunno what you're doing wrong, but you must be doing something wrong because I just tested this on my systems and it worked OK! There were only two items I changed: /etc/auto.master: #+ I don't have this '+' entry; according to auto.master(5), the # + [map-type,format:]map[options] can be "included from its source # as if it were itself present in the master map; dunno if you have # such a "source"... /home/user/shares /etc/auto.shares # Use an absolute pathname for the mapfile

Did you actually restart the autofs service? Changes to the maps are accomodated on the fly, but changes to /etc/auto.master require a /etc/init.d/autofs restart

Did you try to access /home/user/shares/storage or /home/user/shares/mythtv ?, they won't be mounted until you try to access them (try ls $dir)....
