Bhaskar, Rajesh Reddy, Kasturi and I were there when this bug was seen. Couple of observations: 1) There was no split-brain as far as the AFR changelogs are concerned. 2) The dirty xattr value on /.shard was constantly increasing on the source bricks, as IO kept progressing. Krutika,
Thanks for this information. If there is dirty marker, directory will be treated as conservative merge, since so sources will be set, it will be assumed as split-brain.
Bhaskar,
Do you have sos-reports of this issue? We need to find out why dirty xattr keeps increasing.
