<span style="font-family:"Calibri",sans-serif;color:black">This is intermittent for most files, but eventually if a file is large enough it will not write. The workflow is SFTP tot he client which then writes to the volume over FUSE. When files get to a certain
point,w e can no longer write to them. The file sizes are different as well, so it's not like they all get to the same size and just stop either. I've ruled out a free space issue, our files at their largest are only a few hundred GB and we have tens of
terrabytes free on each brick. We are also sharding at 1GB.</span><o:p></o:p></p>
