Volume type such as stripe and distributed stripe, may fail operations on the mount point with EIO if the first subvolume is "down". During a replace-brick operation, src brick is stopped and restarted with pump xlator inserted into the server graph. During which operations running on the mount can fail. This is a known limitation of replace-brick with stripe, distributed stripe type volumes.
