Bertrand Delacretaz commented on SOLR-207: ------------------------------------------ I think find -maxdepth is not supported on Solaris. And the -t option in my previous example was obviously wrong. I'm not sure if ls -r sorts by filename everywhere (but I have no evidence that it does not). The most portable version might be ls ${data_dir} | grep snapshot\\. | grep -v wip | sort -r | head -1 > snappuller inefficient finding latest snapshot > ---------------------------------------------- > > Key: SOLR-207 > URL: https://issues.apache.org/jira/browse/SOLR-207 > Project: Solr > Issue Type: Bug > Components: replication > Reporter: Yonik Seeley > Attachments: find_maxdepth.patch > > > snapinstaller (and snappuller) do the following to find the latest snapshot: > name=`find ${data_dir} -name snapshot.* -print|grep -v wip|sort -r|head -1` > This recurses into all of the snapshot directories, doing much more disk-io > than is necessary. > I think it is the cause of bloated kernel memory usage we have seen on some > of our Linux boxes, caused > by kernel dentry and inode caches.
