Subject [jira] [Resolved] (CASSANDRA-8327) snapshots taken before repair are not cleared if snapshot fails
Date Mon, 24 Aug 2015 16:31:47 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-8327?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Yuki Morishita resolved CASSANDRA-8327.
---------------------------------------
       Resolution: Won't Fix
    Fix Version/s:     (was: 3.x)

CASSANDRA-7357 added clean up for repair snapshot leftovers.
I will add fix to Sankalp's finding in CASSANDRA-10057 as we need to fix repair hang there
also.

> but the system.log reports the following error which suggests the snapshot failed:

session completed with the following error java.io.IOException: Failed during snapshot creation.
> the problem is that the directory for the snapshots that fail are just left on the disk
and don't get cleaned up. They must be removed manually, which is not ideal.
