<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Fluster V3.0.0 in two SuperMicro servers each with 8x2TB hard drives<br>
configured as JBOD. I use Gluster to replicate each drive between<br>
servers and the distribute across the drives giving me approx 16TB as<br>
a single volume. I can pull a single drive an replace and then use<br>
self heal to rebuild. I can shutdown or reboot a server and traffic<br>
continues to the other server (good for kernel updates). I use logdog<br>
to alert me via email/text if a drive fails.<br><br></blockquote></blockquote><div><br></div><div>That's ok for me, but my question is:</div><div>how does gluster detect a failed cluster on a disk?</div><div>Will it detect properly and start serving data from the other server?</div>
<div><br></div><div>In case of whole disk failure its easy, disk is not working and gluster will</div><div>use the other server, but if the disk is ok and only a single sector</div><div>is not readable? </div></div><br>
