NFS in Linux from HP-UX

Tonatiuh — Wed, 17 Sep 2008 21:30:32 GMT

Red Hat Enterprise Linux 3.8
HP-UX 11.11

NFS Mount directories before to mount it...

Linux directory ownership: oracle:oinstall
HP-UX directoru ownership: oracle:oinstall

But when I mount the HP-UX directory from Linux, the ownership of the directory in linux change to 101:ident

# umount /apptmp/pruebas
# ll
total 4
drwxr-xr-x 2 oracle oinstall 4096 Aug 11 02:37 pruebas
# mount -t nfs 172.16.110.41:/data/LCTEST/TMP /apptmp/pruebas
# ll
total 25
drwxrwxrwx 2 101 ident 24576 Sep 18 2008 pruebas

Any idea?

HP-UX:
uid=101(oracle) gid=101(oinstall) groups=102(dba)

Linux:
uid=500(oracle) gid=500(oinstall) groups=500(oinstall),501(dba),502(dbo)

NFS doesn't interpret, extrapolate, or guess about UIDs and GIDs. If you want them to be owned by the same user and group, you must be sure the UIDs and GIDs match for those users and groups on both systems.

Shalom,

You have inconsistencies in the numeric user id's between the HP-UX and Linux system.

To get permissions and ownership to be right you need to solve those issues or use NIS and make one server the master and one the slave.

Plesae match oracle user UID on both the machine. That will solve the problem
