[Lustre-discuss] Where should SHARED_DIRECTORY of acc-sm cfg variable set to?

[Surya, Prakash B.]

Perhaps it would be beneficial to add Andreas's comment to the source to avoid any future confusion?

{code}
    # This is used by a small number of tests to share state between the client
    # running the tests, or in some cases between the servers (e.g. lfsck.sh).
    # It needs to be a non-lustre filesystem that is available on all the nod
    export SHARED_DIRECTORY=${SHARED_DIRECTORY:-"/tmp"}
{/code}

This is used by a small number of tests to share state between the client
running the tests, or in some cases between the servers (e.g. lfsck.sh).
It needs to be a non-lustre filesystem that is available on all the nodes.
