A month or two ago we expanded a lustre instance (added an OSS+OTSs to a fairly full file system). Since then, we’ve seen IO patterns that heavily favor the new OSS/OSTs. In the default allocation strategy, is this to be expected in a file system with heavily disparate free space among OSTs?
We don’t really have the luxury of rebalancing things (assuming the method for doing such is still “re-write/copy files on old OSTs and let the allocation strategy handle it"), unfortunately, so we’re just looking to confirm the behavior. _______________________________________________ lustre-discuss mailing list [email protected] http://lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org
