    Description

      When a client is misconfigured, it may try to connect to an OST which does not exist. This can cause these messages on the server:

      LustreError: 137-5: UUID 'ls1-OST0011_UUID' is not available for connect (no target)
      LustreError: 137-5: UUID 'ls1-OST0012_UUID' is not available for connect (no target)
      LustreError: 137-5: UUID 'ls1-OST0012_UUID' is not available for connect (no target)
      LustreError: 137-5: UUID 'ls1-OST0011_UUID' is not available for connect (no target)
      

      If the client is never cleaned up, this will go on indefinitely. This should really be cleaned up, and a message should only be printed a single time for this type of error (to help spot mis-configured clients).

      For example, it would be better if the server kept a list of clients that have tried to connect to this non-existent OST, and only print a message once per client.

      We tend to hit this when we re-purpose our development filesystems without rebooting/remounting clients, which then clutters the server log.
