| I was now able to catch the split brain log:
sudo gluster volume heal storage2 info Brick storage3:/data/data-cluster <gfid:256ca960-1601-4f0d-9b08-905c6fd52326> <gfid:7a63a729-c48f-4a00-9040-c3e2a0710ae6> /dms/final_archive - Is in split-brain
Status: Connected Number of entries: 3
Brick storage4:/data/data-cluster <gfid:276fec9a-1c9b-4efe-9715-dcf4207e99b0> /dms/final_archive - Is in split-brain
Status: Connected Number of entries: 2
Since 24h, after upgrading from 4.0 to 4.1.7 one of the servers, the heal shows this:
sudo gluster volume heal storage2 info
Brick storage3:/data/data-cluster
<gfid:256ca960-1601-4f0d-9b08-905c6fd52326>
<gfid:7a63a729-c48f-4a00-9040-c3e2a0710ae6>
/dms/final_archive - Possibly undergoing heal
Status: Connected
Number of entries: 3
Brick storage4:/data/data-cluster
<gfid:276fec9a-1c9b-4efe-9715-dcf4207e99b0>
/dms/final_archive - Possibly undergoing heal
Status: Connected
Number of entries: 2
The same files stay there. From time to time the status of the /dms/final_archive is in split brain at the following command shows:
sudo gluster volume heal storage2 info split-brain
Brick storage3:/data/data-cluster
/dms/final_archive
Status: Connected
Number of entries in split-brain: 1
Brick storage4:/data/data-cluster
/dms/final_archive
Status: Connected
Number of entries in split-brain: 1
How to know the file who is in split brain? The files in /dms/final_archive are not very important, fine to remove (ideally resolve the split brain) for the ones that differ.
I can only see the directory and GFID. Any idea on how to resolve this situation as I would like to continue with the upgrade on the 2nd server, and for this the heal needs to be done with 0 entries in sudo gluster volume heal storage2 info
Thank you in advance, Milos.
