Has anyone used netapp as the NFS for the multi instance Queue Manager setup. when I attempt to test the concurrent writes on both the servers seeing the below error
-bash-3.2$ amqmfsck -c /files1/ha
Start a second copy of this program with the same parameters on another server.
Writing to test file. This will normally complete within about 60 seconds.
.........
AMQ5667: Error executing system call 'fcntl(F_SETLKW)[c]' on file
'/files1/ha/amqmfsck.wrt', errno 121 ('Remote I/O error').
seeing the same error on both the servers. Can anyone shed some light on this?
Thanks

What do you mean by concurrent writes? Are you expecting both qmgrs to update the same filesystem concurrently?

Have you configured netapp to provide NFS *V4*?
You have to use NFS V4 to use multi-instance. |

Are you following some document from IBM that tells you how to implement MI?

Thanks for your replies. I'm using NFS version 4 on netapp.
I did mount from both the servers to the shared disk. Testing the concurrent writes on to the shared disk from the servers.
Thanks

but still not having success. stuck at this error
bash-3.2$ amqmfsck -c /files1/ha
Start a second copy of this program with the same parameters on another server.
Writing to test file. This will normally complete within about 60 seconds.

AMQ5667: Error executing system call 'fcntl(F_SETLKW)[c]' on file
'/files1/ha/amqmfsck.wrt', errno 121 ('Remote I/O error').

If the storage is NFSv4, it should work. We used GPFS so I do not know about NFS but again it is IBM recommendated so it should work.
I suspect the storage has not been correctly setup. I am not a hardware person, so I can not tell you but I can tell certainly that is it storage setup issue not a MQ issue.
We have setup and using ( went live last week) MI qmgr.
Thanks

Raise this with Netapp. The error originates in the layers below the OS. |
