So now that I have my cluster on 3.7.14 and sharded and working I am of course looking for what to break next.
Currently each of 3 nodes is on a 6 disk (WD Red 1TB) raidz6 (zil on mirrored ssd), which I am thinking is more protection than I may need with a 3 way replica. I was going to one by one change them to basically raid10 letting it heal in between.
Is best way to do that a systemctl stop glusterd, should I just kill the brick process to simulate a brick dying, or is their an actual brick maintenance command?
If /etc/glusterfs is unchanged and /var/lib/glusterd is unchanged will doing a heal full after reboot or restarting glusterd take care of everything if I recreate the expected brick path first?
Are the improvements in 3.8 for sharding significant enough I should first look at updating to 3.8.2 when released in few days?
