The first error you saw might be related to the fact the recent mount.nfs defaulted to version 4 since nfs-kernel-server >= 1.2.1 IIRC. While you can workaround this by using "vers=3" option as you did, leaving NFSv4 as default might possibly break existing setups (Ccing Neil Brown, nfs-utils maintainer for SUSE) for further opinion/comments. Does using the mount option 'nolock' help? The 'nolock' mount option is generally recommended particularly when the export is /var (or /usr) as they contain files used by the NLM implementation. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Yes, using the 'nolock' mount option, we can mount the directory. However, we want to perform an automatic installation. Is there any way to pass the options "vers=3,nolock" to the installer automatically? The options would probably have to be communicated via kernel-options?

I'm not sure whether it is possible to pass nfs options to auto installer. But as an alternative, you could try using NFSv4 itself instead of NFSv3. NFSv4 configuration is simple: - On the Server, edit /etc/exports and add "fsid=0" to the options for e.g. /Engineering 192.168.1.15(rw,sync,fsid=0) - #exportsfs -r (to re-export all dirs) - While using autoyast on the client skip mentioning the exported directory for e.g. If you had used something like: nfs://192.168.216.12/path/to/root to use NFSv4, just say: nfs://192.168.216.12 Note: * NFSv4 has a concept of a root of the overall exported filesystem. The export point exported with fsid=0 will be used as this root.

https://bugzilla.novell.com/show_bug.cgi?id=649871 https://bugzilla.novell.com/show_bug.cgi?id=649871#c6 --- Comment #6 from Suresh Jayaraman 2010-12-14 08:05:02 UTC --- Looking more closely, it appears that the problem here is Old AIX server returning "EREMOTEIO" instead of "ENOENT" error. Linux clients fallback to NFSv3 in case of ENOENT error as expected. I verified this in a 11.3 Server Vs 11.3 client setup and there were no errors observed. AFAIK, there is no way to pass NFS mount options via Autoyast. I think apart from getting AIX server fixed, the other option would be to make linux client handle EREMOTEIO error from the legacy AIX servers. I have built the nfs-utils/nfs-kernel-server packages with the above mentioned fix and made it available here: http://www.suse.com/~sjayaraman/test-pkgs/ Could you please test this package and see whether the error go away? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

There is no way for me to be sure whether the Linux workaround for patch fixes this problem or not and in any case legacy AIX servers have to be fixed to return "ENOENT" instead of "EREMOTEIO".
