Comment 7 Prasad Desala 2018-08-08 11:04:27 UTC

Verified this BZ on glusterfs version: 3.12.2-15.el7.x86_64.

1) Created a distributed-replicate volume 4x3 and start it.
2) FUSE mount it on multiple clients.
3) Create a file "f1"
4) set cluster.self-heal-daemon to off and cluster.quorum-type to none
5) Bring down b1,b2 in a replica pair.
6) Write some data to file "f1"
7) Bring back the down bricks. b1 and b2
8) Now, bring down b3 in the replica pair.
9) Write some data to the file "f1"
10) Bring back b3

Now, file will be in split-brain. Append some data to the file, it throws EIO error.
Hence, moving this BZ to Verified.
