Jonathan Ellis resolved CASSANDRA-670. -------------------------------------- Resolution: Won't Fix not much we can do about os-level issues. > commitlog sync seems to be affected by i/o on other devices > ----------------------------------------------------------- > > Key: CASSANDRA-670 > URL: https://issues.apache.org/jira/browse/CASSANDRA-670 > Project: Cassandra > Issue Type: Bug > Reporter: Jonathan Ellis > Priority: Minor > Attachments: 670.txt > > > doing some testing on a system with commitlog on a separate device + xfs > filesystem, syncing shouldn't have to wait for IO from the data filesystem, > but we're seeing CL sync times up to almost 5s when the data fs is extra busy > (adding bonnie++ to normal cassandra activity helps reproduce this). > CASSANDRA-668 band-aided this a bit but it would be good to figure out what's > going on here: is it our code at fault? the JVM's? the linux kernel's? -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
