Bug ID 90314 Title Heavy file deletion loads can make a filer less responsive
Basically the fix was setting these hidden options to de-prioritize volume deletion related operations (these ops had swamped the netapp during an aborted vfiler migrated (that's another related issue))
options wafl.trunc.throttle.system.max 30 options wafl.trunc.throttle.vol.max 30 options wafl.trunc.throttle.min.size 1530 options wafl.trunc.throttle.hipri.enable off options wafl.trunc.throttle.slice.enable off
So far, we have not seen the issue again.
internal snapshot, snapmirror, dedup operations can account for a large percentage of load and IO _______________________________________________ Toasters mailing list Toasters@teaparty.net http://www.teaparty.net/mailman/listinfo/toasters
