<p>Hi Karthik,</p>
<p><br></p>
<p>Thanks a lot for the explanation.</p>
<p>Does it mean a distributed volume health can be checked only by "gluster volume status " command?</p></div></blockquote></span><div>Yes. I am not aware of any other command which can give the status of plain distribute volume which is similar to the heal info command for replicate/disperse volumes. <br></div><span class="gmail-"><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div style="font-size:10pt;font-family:Verdana,Geneva,sans-serif">
<p>And one more question: cluster.min-free-disk is 10% by default. What kind of "side effects" can we face if this option will be reduced to, for example, 5%? Could you point to any best practice document(s)?</p></div></blockquote></span><div>Yes you can decrease it to any value. There won't be any side effect.<br></div></div></div></div></blockquote><div>Small correction here, <span class="gmail-m_-126915862793367685gmail-im">min-free-disk should ideally be set to larger than the
largest file size likely to be written. Decreasing it beyond a point
raises the likelihood of the brick getting full which is a very bad
state to be in.<br>Will update you if I get some document which explains this thing.

<div>Hi Anatoliy,<br><br></div>
The heal command is basically used to heal any mismatching contents between replica copies of the files.</div>
For the command "gluster volume heal <volname>" to succeed, you should have the self-heal-daemon running,<br>which is true only if your volume is of type replicate/disperse.</div>
In your case you have a plain distribute volume where you do not store the replica of any files.</div>
So the volume heal will return you the error.<br><br></div>
Regards,</div>
Karthik</div>
