This morning I reconnected it and ran heal info and we have about 30000 entries to heal (15K from gfs-vm000 and 15k from gfs-vm001, 80% are all gfid, 20% have file names). It's not feasible for us to check the individual gfid so we kinda rely on gluster self heal to handle those gfid. The "/" is a concern because it prevents us from mounting nfs. We do need to mount nfs for some of our management because gluster fuse mount is much slower compared to nfs when it comes to recursive operations like 'du' </div><div><br></div><div>Do you have any suggestion for healing the metadata on '/' ?</div><div><br></div><div>Thanks</div><div>Anh</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Jul 3, 2018 at 8:02 PM, Ravishankar N <span dir="ltr"><<a href="mailto:ravishankar@redhat.com" target="_blank">ravishankar@redhat.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<p>Hi,</p>
<p>What version of gluster are you using?</p>
<p>1. The afr xattrs on '/' indicate a meta-data split-brain. You
can resolve it using one of the policies listed in
<a class="m_3342788517930548362moz-txt-link-freetext" href="https://docs.gluster.org/en/latest/Troubleshooting/resolving-splitbrain/" target="_blank">https://docs.gluster.org/en/<wbr>latest/Troubleshooting/<wbr>resolving-splitbrain/</a></p>
<p>For example, "<code>gluster volume heal gv0 split-brain
latest-mtime / "<br>
</code></p>
2. Is the file corresponding to the other gfid
(81289110-867b-42ff-ba3b-<wbr>1373a187032b) present in all bricks? What
do the getfattr outputs for this file indicate?<br>
<br>
3. As for the discrepancy in output of heal info, is node2 connected
to the other nodes? Does heal info still print the details of all 3
bricks when you run it on node2 ?<br>
