AIX

Hi,
Can someone help me on this?

I'm not able to enable a well working mounting process for NFS filesystems on boot time.

On the server side (AIX 5.2) everything seems to be OK and correctly exported, seeing other clients (AIX 5.2) are able to mount normally on boot time.

On a client in particular (AIX 5.2) the NFS mount on boot does not works, I have to mount manually (mount -a) after each reboot.
NFS deamons start normally at boot (at least this logs is saying...).

I checked /etc/filesystems, the hostnames resolutions, /etc/inittab, /etc/rc.nfs

To workaround this problem I had to configure and enable "automount" in order to mount automatically the NFS filesystems at first access into the filesystem.

The AIX box is in HACMP cluster with another node (I don't know if the other node is affected by the same symptom), so maybe there is something to check within the HACMP configuration?

Anyway the only purpose of this HACMP cluster is sharing concurrent volume groups between nodes.

Any idea?

Thanks a lot!

Not sure if this is your problem or not since you said you already checked /etc/filesystems. But take a look again and make sure the entry for your filestsem has the line "mount = true".

HACMP changes IP adresses of interfaces (and it does that in a different way on HACMP 4.x and HACMP 5.x), so maybe you have the NFS mount exported to the service address, but the service address is not on the interface at boot time, because the interface still has its non-service (boot-address in HACMP 4.x-speak) address?

In this case you would have to include the NFS mount into the startup script of the HACMP resource group (don't forget to umount it in the stop-script too in this case).

I hope this helps.

Hi, thanks for the hint, anyway is mount=true ...

Hi,
Thanks for your reply.
I'm investigating about what you suggested... I'll keep you posted!

Hi,
I did check the HACMP configuration and the network configuration.
I didn't find anything wrong so, to workaround the problem, I will implement the automount feature, that basically solve the problem.
Anyway I'm going to escalate the problem, seeing my company has a full support from IBM... I'm going to use it.

I will update the post as I get an answer.

Thank you!
