Your devices are reported as:
mpath2 (36742b0f0000075500000000000002de4) dm-2 NFINIDAT,InfiniBox
size=954M features='0' hwhandler='0' wp=rw
`-+- policy='round-robin 0' prio=-1 status=active
  `- 2:0:0:3 sdd 8:48 active undef running

Maybe there is a false positive in those fixes.

To continue on this we need very exact description on your device type, storage backend, and anything else that defines your disk setup in HW&SW.

Then depending on availability of such devices or at least a similar setup a reproduction can be tried - if not possible one might suggest different things to be tested on your end, but that is way slower and more error prone.
