Is there a way to query how much fragmentation there is in a filesystem? We've got a large filesystem which was allowed to get really full before it was expanded considerably, and we also had deduplication turned on briefly, which caused the dedupe table to get very, very big. While the application that stores data rewrites a lot of it, the dedupe table still has a lot of entries in it, etc.
We can easily queue up data to move it between filesystems, and have scratch space elsewhere, so I'm thinking of moving data off and then back on again, but if there's a painless way to see how bad the fragmentation is (and tell if moving data off+on again makes a difference), I'd love to know. Thanks! Brett PS:Thanks to those who replied about my earlier questions regarding ZIL and L2ARC. I've experimented with both- thanks! _______________________________________________ OpenIndiana-discuss mailing list [email protected] http://openindiana.org/mailman/listinfo/openindiana-discuss
