Before you rush into posting and reposting issue on the mailing list try first to:
Get into glustefs irc channel at freenode.net and try to get live help.
And it will not help you to spam the list....
You need to post the relevant information:
glusterfs versions of server and client
OS version
df output
etc..

I can still do not understand the basics about your setup..

This seems like such an innocent question.  I have a firewall system
controlling tunnels all over the USA.  It’s an HA setup with two nodes.
And I use Gluster to keep all the configs and logs replicated.

It’s an active/standby system and it’s been in place for something like
3 years.  The standby had a catastrophic hardware failure a while ago
and it looks like it needs a new motherboard.   We have people
rebuilding the hardware.  The standby hard drive seems fine.

But now the primary system repeatedly stalls its I/Os, sometimes to
directories that aren’t even part of Glusterfs.  And the problem is
getting worse day by day, hour by hour.  Before they barbecue me, how do
I tell Gluster to temporarily take the failed node offline while the
motherboard is replaced, then put it back in service and copy everything
over to it?  I don’t want to completely remove the brick because when
the hardware is repaired and we start it up again, I want it to join
back up and have everything replicate over to it.

So for now – what can I do on the surviving node to tell it not to try
to replicate until further notice, and then how to I tell it to go back
to normal when I get the standby system back online?

Thanks
