[jira] [Created] (ARTEMIS-2483) BlockSize is not used on sync calculation on CLI create

clebert suconic created ARTEMIS-2483:
----------------------------------------

             Summary: BlockSize is not used on sync calculation on CLI create
                 Key: ARTEMIS-2483
                 URL: https://issues.apache.org/jira/browse/ARTEMIS-2483
             Project: ActiveMQ Artemis
          Issue Type: Bug
          Components: Broker
    Affects Versions: 2.10.0
            Reporter: clebert suconic
            Assignee: clebert suconic
             Fix For: 2.11.0


During an ./artemis create, the block size is not passed to libaio, letting it use the default value from the device.

This is particularly dangerous as some MDS providers will return a huge block size (e.g. ceph-fs).

instead we should always use 4K if calculation sync times on libaio.
