I tried out OpenEBS Replicated — and it is promising — but it doesn’t really seem mature yet. Im a bit scared to put production critical data into it.
A lot of times, finding a solution further up the stack or settling for backups ends up being more robust and reliable. Many folks have been burnt by all the fun failure scenarios of replicated filesystems.
What I would like to do is develop a system where applications just need to request replicated volumes which span a specific failure domain and push that logic down to the platform.
Doing anything special with your config? I already am setting placement options and played with replica options.
My only hope has been to wait for the V2 engine to become stable.
