<br>
I have three storage domains backed by gluster in my
environment (hostedstorage, data and vmstore). I would want
to move the storage domains into maintenance. Have couple of
questions here.<br>
<br>
1) Will moving master storage domain into maintenance have
some impact on hostedstorage?<br>
<br>
2) I see that moving master storage domain into maintenance
causes HostedEngine VM to restart and moves hosted_storage
from active to Unknown state. Is this expected?<br>
<br>
3) master storage domain remains in "Preparing for
Maintenance" and i see the following exceptions in the
engine.log.<br>

I don't know why the reconstruct failed, it says here it's wrong master domain version.<br></div><div> <br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div bgcolor="#FFFFFF" text="#000000"><span class=""><blockquote type="cite"><div class="gmail_extra"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
