yes we have exported 3 files from the VNX and I can see them on the VNX DM, however from my Linux client I cannot mount them i.e. # mount 10.10.2.108/blackboarddb /blackboard”.

be more specific, what permission issues are you having, what have you done to fix permissions ? (chmod, chown)

we use Blackboard, we actually used to run in on Celerra but now it has been migrated to Isilon. Oracle DB was on block storage (VMAX) but content was on NFS exports. We did not do anything special on Celerra, just regular export where Blackboard server has root, read/write and access permissions.

do you know i there is an EMC white paper for deploying a VNX NFS share for the this application Blackboard this is an education application that uses oracle as a DB, and is part of this NFS permissions error.

this sound great maybe you can help me here the client is running a procedure called oracle installer and we get this oracle issue has
[root@bbdata]# df
10.10.2.108:/blackboarddb 303200000 608 303199392 1% /usr/local/oracle/oradata
[root@bbdata oracle]# ll
total 16
drwxr-xr-x 7 root root 1024 Nov 21 00:53 oradata
drwxr-xr-x 2 oracle oinstall 4096 Nov 21 14:06 oraInventory
drwxr-xr-x 3 oracle oinstall 4096 Nov 5 15:08 product
[root@bbdata local]# chown oracle.oinstall oracle/oradata/
chown: changing ownership of `oracle/oradata/': Operation not permitted
can i just do the following
# chmod g+rw oracle/oradata/ to get this to run...?

Jaloma:
I've seen this oracle installer issue even when the filesystems were laid out on Local Disks (non-SAN/non-NAS devices). I think it has something to do with the traces of files left over after one unsuccessful attempt of Oracle Installation. If your DBA is running Oracle Installer for the second (or more ) time, then ask him to delete or move the directories to another place and re-run the installer once again.
Regards,
-Kennedy

ok I can do that but the person doing the work is not an Oracle DBA, also i was looking at the chown command and it looks wrong ...?
should it be # chown root oracle
or # chown : oracle/oradata
thoughts,

you need to specify "chown username:group "

so this looks incorrect
[root@bbdata local]# chown oracle.oinstall oracle/oradata/
should it be # chown oracle:oinstall oracle/oradata/
thoughts...?
