Local fileystem Mount point is in Cluster Aware filesystem

[UVA]

Hi

Greetings of the Day!

We have Three Volume Groups in our cluster system presented from the SAN

/dev/VG_EPR_DATA
/dev/VG_EPR_LOG
/dev/VG_EPR_ORA
The /dev/VG_EPR_DATA , /dev/VG_EPR_LOG are Cluster Aware and /dev/VG_EPR_ORA is local VG for the node1

The /dev/VG_EPR_DATA , /dev/VG_EPR_LOG are contains differnt LVs which are having the failover facility
There is one Lv in /dev/VG_EPR_DATA Volume group called /dev/VG_EPR_DATA/LV_EPR_ORCL and its mount point is /oracle
and /dev/VG_EPR_ORA having only one LV called /dev/VG_EPR_ORA/LV_EPR_ORA and its mount point is /oracle/EPR/102_64

Now my mount point for the /dev/VG_EPR_ORA/LV_EPR_ORA is /oracle/EPR/102_64, since my /dev/VG_EPR_DATA/LV_EPR_ORCL is cluster aware
and it contails the mount point of /dev/VG_EPR_ORA/LV_EPR_ORA. due to this my /dev/VG_EPR_ORA/LV_EPR_ORA filesytems not getting mount automatically needs to mount mannully every time.

what will be the solution for the above sinario

Let me get this straight...

you have a filesystem that is part of a cluster and is mounted at /oracle

you have another filesystem that is not part of the cluster and is just local, and you want to nount this at /oracle/EPR/102_64

That's just not going to work - having a local filesystem mountpoint on a clustered filesystem is just plain dumb.

This isn't a question of 'finding a solution', this is just bad design. The only way this is ever going to work is to have a totally seperate mount point outside of the filesystem controlled by the cluster. Not least cos your cluster failover will never work properly as you have it now...

So I'd suggest you mount the LV /dev/VG_EPR_ORA/LV_EPR_ORA somewhere like /oracle2/EPR/102_64 or whatever.

Hi Duncan ,

Your understanding absolutely correct,

Hi

But i need some more details

like shall i put a entry mount /dev/VG_EPR_ORA/LV_EPR_ORA /oracle/EPR/102_64 in to the CUTOMER_DEFINED_FUNCTIONS in the control file.

Did you not read what I put in my last post?

This is NOT a good idea...

Let's say as you detail that you put a mount command in the customer defined run commands... now what happens when you want to failover the package to the other node? What happens when the package is running on the other node and then fails over to this node?

You need to rethink your filesystem and directory structure or you will just end up with a messy hack which you *will* regret.

Hi Duncan,

I Agree with you,

Thanks for your honest reply.
