the gfid looks the same. I'm not sure what gluster volume heal info split-brain is reporting when the GFID matches, and for all 4 nodes in the devstatic volume.

Being / on the same replicate, how would I safely resolve this issue? Is
it really going to require me to delete the root of each node and heal?
I hope not, the entire volume is about 1TB.
No, it is likely that the root is only in metadata split-brain.
What does the getfattr output of '/' show on the bricks? https://github.com/gluster/glusterdocs/blob/master/Troubleshooting/split-brain.mdshould tell you how to resolve split-brains.
Thank you,
