No, because the remote-attached SSDs are part of the ZFS pool and any drive 
failures a t that level are the responsibility of ZFS in that case to manage 
the failed drives (eg. with RAID) and for you to have system monitors in place 
to detect this case and alert you to the drive failures.  This is no different 
than if the drives inside a RAID enclosure fail. 

Lustre cannot magically know about drives below the filesystem layer have 
problems. It only cares about being able to access the whole filesystem, and 
that the filesystem is intact even in the case of drive failures.
