how to persist mq data

[har2103]

hi team,

we are migrating to openshift and using gluster fs to mount mq data. we are mounting /mnt/mqm-data and /mnt/mqm-log in glusterfs. we see the qmgr data is getting persist along with log. but when we send some messages in queue after it restart the pod all messages are getting lost.

Need more info how we can persist mq data in persistent volume.

Can you confirm that you are using persistent messages? For example, a common issue we see is people using utilities like amqsput for testing, which don't set persistent messages by default (you can set the default persistence value for messages on the queue itself).

Otherwise, we would need to see more information about how you've set up your Persistent Volumes.

Please note that we have tested Gluster V3, V4 and V5, and they all have issues which make it an unsupported filesystem for MQ. See Testing statement. Note however, that this is due to a locking limitation, and is not the problem you are seeing here.

Hi,

I was trying to test with amqsput which was not persisting in pvc. I tested with application then i was able to see. but for some queue we observed its still not persisting which is very weird behavior, Also another observation when we make queue property Defpersist to true the processing is happening very slow. MQ is picking messages very slow.

Please let me know what all pvc info you need?
