NFS RW issues on AIX
Hello Experts,
I have an NFS server which is a EMC device and on which one of the mounts that I need is exported as the below when I run "showmount -e server"
/data_db (everyone)
I have an AIX server(server1) to which the share is auto mounted and here is the how its mounted..
data_db -noac,rsize=32768,wsize=32 768 server:/data_db
When i try to access the share by cd to /data_db I am able to read and write using oracle ID,
But I have 2 other AIX servers in this same enviroment, which are automounted with the same permissions but when I try to cd to /data_db I am able to list all the content but when I try to write this as oracle, I am not able to touch any file..
touch: 0652-046 Cannot create abc
so i tried to change the permissions and here is the error i get
chown oracle:dba data_db
chown: data_db: The file system has read permission only
before changing the permissions, these are the default permissions
drwxrwxrwx 7 root system 24576 Oct 06 00:26 data_db
Thanks,

Should we assume you unmounted the NFS share first prior to changing the ownership/permissions of the mount point? I've had inconsistencies in the past when not having done this first, so that may be a reason.
1. Unmount the NFS share
2. Change owner/perms on mount point
3. Re-mount NFS share
Also, in the past for Oracle RMAN backups, I've used additional options to mount a share like;
rw,bg,hard,intr,timeo=600,
