Otherwise, this behaviour should be well > documented in mdconfig(8) and/or md(4). > Fixed in revision 1.44 of mdconfig(8) I have included the commit log for your reference: When using files as backing stores for devices, and the user has requested the device be created read+write, check to see if the backing store is read only through the use of the access(2) system call. If this check fails returning EACCES, EPERM or EROFS then gracefully downgrade the access to read only. Also print a warning message to stderr, informing the user that the access mode they requested is not available. This behavior used to be handled by md(4) but was changed in revision 1.154 Discussed with: pjd, phk, Dario Freni <saturnero at freesbie dot org> Reviewed by: phk -- Christian S.J.
