Hi Kevin, If you actually ran into a 'read-only filesystem' issue, then it could possibly because of a bug in AFR that Pranith recently fixed. To confirm if that is indeed the case, could you tell me if you saw the pause after a brick (single brick) was down while IO was going on? -Krutika On Wed, May 25, 2016 at 1:28 PM, Kevin Lemonnier <lemonnierk at ulrar.net> wrote:> > Whats the underlying filesystem under the bricks? > > I use XFS, I read that was recommended.
