[jira] Updated: (ZOOKEEPER-483) ZK fataled on me, and ugly
[ https://issues.apache.org/jira/browse/ZOOKEEPER-483?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
ryan rawson updated ZOOKEEPER-483:
----------------------------------
Attachment: zklogs.tar.gz
here is the complete log set from all 5 of our quorum members for the entire day. note that the event happens around 12:30 pm local (PDT) time in the log. I restarted the 3 crashed machines at about 13:30.
They were not run under supervision, but clearly they should. The machines in question only have 1 disk, since they also run other hadoop things, and I was hoping that the quorum model would provide reliability even if the local disk isnt 100%. Although, having said that, the local disk seems to be ok, since nothing else on them has died.
