ASF GitHub Bot updated ZOOKEEPER-3082: -------------------------------------- Labels: pull-request-available (was: ) > Fix server snapshot behavior when out of disk space > --------------------------------------------------- > > Key: ZOOKEEPER-3082 > URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3082 > Project: ZooKeeper > Issue Type: Bug > Components: server > Affects Versions: 3.6.0, 3.4.12, 3.5.5 > Reporter: Brian Nixon > Priority: Minor > Labels: pull-request-available > > When the ZK server tries to make a snapshot and the machine is out of disk > space, the snapshot creation fails and throws an IOException. An empty > snapshot file is created, (probably because the server is able to create an > entry in the dir) but is not able to write to the file. > > If snapshot creation fails, the server commits suicide. When it restarts, it > will do so from the last known good snapshot. However, when it tries to make > a snapshot again, the same thing happens. This results in lots of empty > snapshot files being created. If eventually the DataDirCleanupManager garbage > collects the good snapshot files then only the empty files remain. At this > point, the server is well and truly screwed. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
