Can you elaborate - is the issue corruption or performance? I've never used Lustre.
- mprovost 6y agoLustre is all about performance, at the cost of being split across multiple distributed systems. So there are opportunities to have different components get out of sync - the metadata servers are usually the weak link. And the more moving parts the harder it is to debug when something goes wrong.
