Re: Continue to work in "degraded mode" (missing brick)

Hi,

This is the expected behaviour for a distribute volume. Files that hash to a brick that is down will not be created. This is to prevent issues in case the file already exists on that brick.

To prevent this, please use distribute-replicate volumes.

Sorry, I meant to say distributed, not replicated!
I'm on 6.4 from CentOs7 SIG.

I was hoping the volume might still be fully usable write-wise, with
files going on the remaining bricks, but it doesn't seem to be the case.
