Ishan Chattopadhyaya commented on SOLR-6184:
--------------------------------------------
[~raintung] Did you try increasing the commitReserveDuration parameter?
Reserving a commit point would ensure that the index files corresponding to the
latest commit point being fetched won't be deleted (due to, for example, lucene
segment merges).
Since it takes ~20 minutes to fetch the index, could you try setting this to
~20-25 minutes, maybe?
> Replication fetchLatestIndex always failed, that will occur the recovery
> error.

> Key: SOLR-6184
> URL: https://issues.apache.org/jira/browse/SOLR-6184
> Project: Solr
> Issue Type: Bug
> Components: SolrCloud
> Affects Versions: 4.6, 4.6.1
> Environment: the index file size is more than 70G
> Reporter: Raintung Li
> Labels: difficulty-medium, impact-medium
> Attachments: Solr-6184.txt

>
> Usually the copy full index 70G need 20 minutes at least, 100M read/write
> network or disk r/w. If in the 20 minutes happen one hard commit, that means
> the copy full index snap pull will be failed, the temp folder will be removed
> because it is failed pull task.
> In the production, update index will happen in every minute, redo pull task
> always failed because index always change.
> And also always redo the pull it will occur the network and disk usage keep
> the high level.
> For my suggestion, the fetchLatestIndex can be do again in some frequency.
> Don't need remove the tmp folder, and copy the largest index at first. Redo
> the fetchLatestIndex don't download the same biggest file again, only will
> copy the commit index just now, at last the task will be easy success.
