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.
