<p dir="ltr">I have been left with the impression that FUSE mounts will read from both local and remote bricks , is that right?</p>
<p dir="ltr">I'm using oVirt as a hyperconverged setup and despite my slow network (currently 1 gbit/s, will be expanded soon), I was expecting that at least the reads from the local brick will be fast, yet I can't reach more than 250 MB/s while the 2 data bricks are NVME with much higher capabilities.</p>
<p dir="ltr">Is there something I can do about that ?<br>
Maybe change cluster.choose-local, as I don't see it on my other volumes ?<br>
What are the risks associated with that?</p>
