Hi, we are running a jewel cluster (54OSDs, six nodes, ubuntu 16.04)
that serves as a backend for openstack(newton) VMs. TOday we had to
reboot one of the nodes(replicated pool, x2) and some of our VMs oopsed
with issues with their FS(mainly database VMs, postgresql) - is there a
reason for this to happen? if data is replicated, the VMs shouldn't even
notice we rebooted one of the nodes, right? Maybe i just don't
understand how this works correctly, but i hope someone around here can
either tell me why this is happenning or how to fix it.
Thanks
Josef
