> Key: BOOKKEEPER-949
> URL: https://issues.apache.org/jira/browse/BOOKKEEPER-949
> Project: Bookkeeper
> Issue Type: Sub-task
> Components: bookkeeper-server
> Affects Versions: 4.3.2
> Reporter: Venkateswararao Jujjuri (JV)
> Assignee: Venkateswararao Jujjuri (JV)
> Priority: Critical
>
> When storage usage goes above threshold, there won't be any writable ledger
> dirs available and bookie turns RO. There can be multiple ways bookie can
> start compaction including isForceGCAllowWhenNoSpace enabled or by other
> means. When this happens the compaction process need to create a new entrylog
> to make progress on compaction. Creation of entrylog will fail because there
> are no writable ledger dirs.
> This is to allow entrylog creation if there is enough disk space even though
> used space is above threshold. Because after compaction space will stay the
> same or go below the threshold.
