swi,

Working with some of my colleagues,

I would look into the "Enable mount access to subdirectories Allow subdirectories below the path(s) to be mounted." settings in the exports. This show up as "All Dirs" in the CLI.

The following command will check all the nfs exports.

# for i in `isi nfs exports list --no-header --no-footer |awk '{print $1}'`; do isi nfs export view $i |egrep  " ID|Path|All Dirs"; echo "-----------------------------------------------";done

Wondering about an export on a higher level directory above RS having this setting enabled allow you to transverse up the directory path.

Also what Version of NFS are you using, would need to know pending the outcome of the above information.

swi,

Wondering if you can grab,

# isi nfs export view

Would be looking to have this for a export that works and an export that does not work to compare the two.

Shane

Thanks Shane for the response. There is no export at higher level which is enabled with 'All Dirs: Yes;' The NFS we are using is NFSv3

How exactly are things mounted on the client? Can you share the outputs of:

mount | grep /ifs

or

grep /ifs /proc/mounts

-- Peter

I compared properties of different exports. They looked same

Changed the names, but here is the  mount output.

Isilon /ifs/PQ/dev/oracle /oramnt/OA      nfs3   Jun 29 15:47 bg,soft,intr,rw

Isilon /ifs/PQ/qa/oracle_cs /usr/oracle  nfs3   Aug 16 01:34 bg,intr,sec=sys,rw

Isilon /ifs/ABC/prod/share /nfs/share       nfs3   Nov 11 16:22 soft,intr,rw

Now the issue is on /oramnt/OA

let us say I traverse to a directory in OA which is sam.

1)CD sam

pwd

/PQ/dev/oracle/sam

2)If I keep on doing cd .., I will be shown all the directories in ifs.

1)CD sam pwd /PQ/dev/oracle/sam

At this stage, what does  df .  print? (mind the . )

Also, is this possible?: cd /PQ/dev/oracle/sam

-- Peter

1)

df .

Filesystem    512-blocks      Free %Used    Iused %Iused Mounted on

Isilon:/ifs/PQ/dev/oracle   104857600  94207744   11% 10649856    11% /oramnt/OA

2)It says me no such file or directory.

Looks like the client is broken in the first place... which flavor of UNIX is it? Any chance to get support for the client side, like analyzing the sent NFS network packets?

Its AIX. I'll try to get hold of someone. How did you say the client is broken?  because it says 'no such file or directory'
