The other item to be aware of is that when OneFS 7.1 was introduced it brought a totally new job engine to the table that permits multiple jobs to run simultaneously, based upon exclusion sets (you can read more about that in the OneFS 7.1 or above admin guides).  The upgrade to 7.1 or later can most likely help you solve this problem, as we've seen with other customers with things like snapshotdelete that is a low priority job, but might have problems completing because other higher priority jobs come along and keep interrupting it.  ~Chris Klosterman Senior SA EMC Isilon Offer & Enablement Team chris.klosterman[NAME].com twitter: [NAME]
Hi Techies,  Anyone see this behaviour from Multiscan job,  As soon as the job starts we are seeing disk IO rise from around 30K to 250K.  We have a 30 Node cluster (20 x X400, 10xNL's) now the other issue appears to be that the job never has time to complete due to snap deletes job having a higher priority. 3 x SSD per X400.  Could some please provide some info on what this job does (Re balancing nodes ? ) and heard that we can break the phases down to their individual jobs ? is this correct ?  And is this a know issue with multiscan ?  Many Thanks  Paul
