Hi all, I had share the server Gemini /u10 to the server Centaurus. /etc/dfs/dfstab ```nohighlight share -F nfs -o root=centaurus /u10 ``` My problem is: in the server Gemini the the owner for /U10 is oracle:dba but when in the server Centaurus, I am not able to change the owner become oracle:dba, it show me oracle:nobody in Server Centaurus. ```nohighlight Server Gemini drwxr-xr-x 4 oracle dba 512 Aug 3 08:26 u10 /etc/group dba:*:101:root,oracle,ora10g ``` ```nohighlight Server Centaurus drwxr-xr-x 4 oracle nobody 512 Aug 3 08:26 u10 etc/group dba::101:oracle,ora10g,mysql,lss ``` How i need to do,to change the owner become oracle:dba for /u10 in server Centaurus? ---

Please checkthe GID of the dba group in both the servers. My guess is that the "nobody" user in centauras is having the same GID of the "dba" user in Gemini. Usually group permissions are set based on the name maching the GID of the NFS share directory on the client side. If this is the case, simply you can change the GID in the NFS client in /etc/group Regards Ramkumar ---

Thanks for ur reply. below is the both /etc/group Gemini ```nohighlight root::0: other::1:root bin::2:root,daemon sys::3:root,bin,adm adm::4:root,daemon,pongla uucp::5:root mail::6:root tty::7:root,adm lp::8:root,adm nuucp::9:root staff::10: daemon::12:root sysadmin::14:pongla smmsp::25: gdm::50: webservd::80: postgres::90: nobody::60001: noaccess::60002: nogroup::65534: sasl::100: dovecot::104: nagios::102: nagioscm::103:nagios dba:*:101:root,oracle,ora10g ``` Centaurus ```nohighlight root::0: other::1:root bin::2:root,daemon sys::3:root,bin,adm adm::4:root,daemon uucp::5:root mail::6:root tty::7:root,adm lp::8:root,adm nuucp::9:root staff::10: daemon::12:root sysadmin::14: nobody::60001: noaccess::60002: nogroup::65534: smmsp::25: gdm::50: webservd::80: postgres::90: users::100: onsite::105: softdev::102:lss,dss,netsys,css,scss,amts,packout,dcm,arch,hsa,eco,ecoman,can guest::102:devp,guest oper::103:coherent,brtv,oracle dba::101:oracle,ora10g,mysql,lss ftp::30000:ftp,coherent,brtv sib::60090:tibco,patrol systems::60095:harvest ``` The nobody have the different GID.. any idea? ---------- Post updated 08-05-09 at 08:25 AM ---------- Previous update was 08-04-09 at 11:55 AM ---------- Hi all , the problem solve solution: unshare the filesystem, and redo again the prosess to share the filesystem. ---

Are you using any naming services? Please post your /etc/nsswitch.conf from both machines. ---

Centaurus and geminy are likely on different NFSv4 domains, probably because they have a different DNS domain defined in /etc/resolv.conf. In such case, groups ids are ignored as they might not match. You can force the domain on both servers by setting NFSMAPID\_DOMAIN in /etc/default/nfs. Search NFSMAPID\_DOMAIN in "man nfs" for details. ---

Both the resolv.conf have the same domain.🙂 ---

These boxes are very likely on different NFSv4 domains. That would explain the group being ignored. Don't focus on resolv.conf and fix your configuration if you want this to be corrected. ---

check the nfs version on both nodes. nfsstat -a or nfsstat -m \ If they differ between the 2 systems, mount them using the same NFS verison and try mount -F nfs -o vers=3 hostname:directory mountpoint ---

This issue is obviously related to NFSv4 being used. I don't get what you mean by different versions at both sides. A single protocol can be used for this mount, it can't be mixed. Downgrading to NFSv3 will fix the problem but it would be better in my opinion to properly configure NVSv4.
