I only remember losing one etcd cluster, and it was due to something along these lines. Data center at the customer site lost power, and we were called when they couldn't recover our software. All the etcd volumes were corrupted, and after volume recovery by the customer IT department, we found all our etcd files corrupted. My best guess is their volume systems simply lied about the fsync, which I've heard of a few times about different vendors. |
