Hi all,
What is the best procedure to follow, to gracefully shutdown and then
reintroduce a glusterd peer?
We are running a v3.1.0 4 peer Distributed-Replicate volume over TCP. Each
glusterd host provides 2 bricks (for a total of 8 bricks) and the bricks are
ordered such that Replicate protects us against the loss of a host. Each
glusterd host also mounts the glusterfs volume using the FUSE client. However,
if we shutdown a host for maintenance, user processes running on the remaining
hosts block on I/O to glusterfs for as much as 1 minute and then again for
almost 5 minutes when the host rejoins the cluster. How can we minimise this
disruption?
Best regards,
Aaron
