Hi Everyone

O/s : Redhat 6.4
Mq : 7.5
IIB version : 9.0.0.4

Two machines node 1 and node2 both are on having same O/s trying to setup multi instance queue managers and nfs shared drive is from node 1.
I can able to touch the shared drive from both nodes i can able to create and make changes to file from both the machines and also having users and groups with same uid's and gid's and also checked with file persmissions but while creating a queue manager pointing to that shared drive with options -md and -ld. Its giving an error

AMQ6239 : Permission denied attempting to access file system location

AMQ7052 : Permission denied attempting to access an INI file

amqmfsck /shared/qmdata

Node 1 the message was The test on directory completed successfully.

Node 2 the message was

AMQ5667: Error executing system call 'chown()' on file

'shared/qmdata/amqmfsck.lck',errno 22 ('Invalid argument')

Thanks

Obviously your NFS setup needs to be looked again

Also, touch is not a good test in this case

amqmfsck is a good test before you setup Multi Instance Queue Manager

I hope you haven't shared all of /var/mqm...
/var/mqm/mqs.ini in particular should be unique to each host. That the content is the same does not matter. Shared memory pipes etc should also be specific to each host.

The only shared parts should really be /var/mqm/qmgrs and /var/mqm/log and maybe /var/mqm/log/archives

Is this caused by the same issue you mention here ?

It looks extremely similar, and so hopefully it's been fixed by the same patching.

Thanks for sharing the solution in the other thread, by the way!
