Reporter: Stéphane Loeuillet
Attachments: zookeeper_crash.log
Got a 5 node cluster running on baremetal servers (with NVMe) used by a
ClickHouse cluster on a separate cluster.
This morning, a crash on the leader did let my clusters unusable as while the
leader crashed, none of the 4 followers did take the lead
zookeeper leader was zookeeper08
05/06/07/09 were the followers
Only a restart of zookeeper05 process did unfreeze the whole cluster
