<br>
might work. a bit many git in there, I know,<br>
but we are dealing with redundancy anyways, after all.<br>
<br>
though the git:// protocol is faster and prefered.<br>
<br>
in case said regression should be the reason for your trouble, of course<br>
you could also go back to 8.3.2 (which does not contain that<br>
regression), or wait for 8.3.3 final.<br>
<br>
or, as I suggested earlier, add "no-disk-barrier; no-disk-flushes;<br>
no-md-flushes;" to your disk {} section, which would be a valid<br>
work-around for said regression.<br>
