Hi Kumaresh
Thanks for the reply/inputs
SAN LUN’s are not defined in
/etc/fstab. They don’t have to be mounted while OS boots. SAN volumes are
the part of Cluster resources groups, they are in control of Cluster services
rgmanager.
I did not understand how we can make it work,
please suggest how we can go ahead.
Regards
Deval

how to dis-allow manual mounting of cluster file system resources?
In your case, I guess removing the SUID on mount for
normal users is the best solution.
This is will prevent non root members from mounting
the file systesm.

I am using one MSA 500 G2 , two no.
of HP DL360 G4P server with HP’s HBA 642, Server installed with RHEL 4 ES
U1 and RHCS4 with lock mgr as DLM
I have to run around 14 different
services in HA mode, I have break them up in two different priority domain.
Now 7 services runs on node1 in HA
mode, node2 is failover host for them,
Remaining 7 services runs on
node2 in HA mode and node1 is failover domain for them.
In my scenario Simultaneous logical
drive access is not required, thus I am not using GFS here
What ever is needed is configured
properly and working fine.
But this cluster is still causes
some data inconsistency error if somebody manually mounts the partitions which
is already in access by other node.
I understand that this is against
the basics of non-shared file system. This can be documented also, but
everybody knows that after 2-3 yrs down the line when support staff replaced by
new people, when they come in with very limited understanding about the running
stuff they can do some mount mistake.(umount is a document screw up, but mount
is here undocumented screw up) every body knows mount is just a simple command,
it does not harm anything, if I just want to read data mount is ok. But in our
case we wanted to restrict other users to use mount command when some logical
volume is already mounted on one node.
I want some help on this, when shared
file system is not implemented. How we can restrict manual mount of cluster
file system resources when its being in use by some cluster services?
Any help would be highly appreciable
here.
