The errors were most likely present in the past.  There simply were no
log messages for them before 1.5.75.  That warning message indicates
that the file server returned a VIO error for the object being accessed.
 If source is a read/write volume, there will be no other replicas and
so all servers will be offline for that object.

You will need to examine the file server logs to identify the reason the
VIO error is being returned.
